`protected void`	`ensureAttributesCapacity(int size)` Make sure that in attributes temporary array is enough space.
`protected void`	`ensureElementsCapacity()` Make sure that we have enough space to keep element stack if passed size.
`protected void`	`ensureEntityCapacity()`
`protected void`	`ensureNamespacesCapacity(int size)`
`protected void`	`ensurePC(int end)`
`protected static int`	`fastHash(char[] ch, int off, int len)` simplistic implementation of hash function that has constant time to compute - so it also means diminishing hash quality for long strings but for XML parsing it should be good enough ...
`protected void`	`fillBuf()`
`int`	`getAttributeCount()` Returns the number of attributes of the current start tag, or -1 if the current event type is not START_TAG
`String`	`getAttributeName(int index)` Returns the local name of the specified attribute if namespaces are enabled or just attribute name if namespaces are disabled.
`String`	`getAttributeNamespace(int index)` Returns the namespace URI of the attribute with the given index (starts from 0).
`String`	`getAttributePrefix(int index)` Returns the prefix of the specified attribute Returns null if the element has no prefix.
`String`	`getAttributeType(int index)` Returns the type of the specified attribute If parser is non-validating it MUST return CDATA.
`String`	`getAttributeValue(int index)` Returns the given attributes value.
`String`	`getAttributeValue(String namespace, String name)` Returns the attributes value identified by namespace URI and namespace localName.
`int`	`getColumnNumber()` Returns the current column number, starting from 0.

  - getProperty
```
public Object getProperty(String name)
```
    Description copied from interface: XmlPullParser
    
    Look up the value of a property. The property name is any fully-qualified URI.
    NOTE: unknown properties are always returned as null.
    
    Specified by:
    
    getProperty in interface XmlPullParser
    
    Parameters:
    name - The name of property to be retrieved.
    
    Returns:
    The value of named property.
  - setInput
```
public void setInput(Reader in)
              throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Set the input source for parser to the given reader and resets the parser. The event type is set to the initial value START_DOCUMENT. Setting the reader to null will just stop parsing and reset parser state, allowing the parser to free internal resources such as parsing buffers.
    
    Specified by:
    
    setInput in interface XmlPullParser
    
    Throws:
    
    XmlPullParserException
  - setInput
```
public void setInput(InputStream inputStream,
            String inputEncoding)
              throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Sets the input stream the parser is going to process. This call resets the parser state and sets the event type to the initial value START_DOCUMENT.
    NOTE: If an input encoding string is passed, it MUST be used. Otherwise, if inputEncoding is null, the parser SHOULD try to determine input encoding following XML 1.0 specification (see below). If encoding detection is supported then following feature http://xmlpull.org/v1/doc/features.html#detect-encoding MUST be true amd otherwise it must be false
    
    Specified by:
    
    setInput in interface XmlPullParser
    
    Parameters:
    inputStream - contains a raw byte input stream of possibly unknown encoding (when inputEncoding is null).
    inputEncoding - if not null it MUST be used as encoding for inputStream
    
    Throws:
    
    XmlPullParserException
  - getInputEncoding
```
public String getInputEncoding()
```
    Description copied from interface: XmlPullParser
    
    Returns the input encoding if known, null otherwise. If setInput(InputStream, inputEncoding) was called with an inputEncoding value other than null, this value must be returned from this method. Otherwise, if inputEncoding is null and the parser suppports the encoding detection feature (http://xmlpull.org/v1/doc/features.html#detect-encoding), it must return the detected encoding. If setInput(Reader) was called, null is returned. After first call to next if XML declaration was present this method will return encoding declared.
    
    Specified by:
    
    getInputEncoding in interface XmlPullParser
  - defineEntityReplacementText
```
public void defineEntityReplacementText(String entityName,
                               String replacementText)
                                 throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Set new value for entity replacement text as defined in XML 1.0 Section 4.5 Construction of Internal Entity Replacement Text. If FEATURE_PROCESS_DOCDECL or FEATURE_VALIDATION are set, calling this function will result in an exception -- when processing of DOCDECL is enabled, there is no need to the entity replacement text manually.
    The motivation for this function is to allow very small implementations of XMLPULL that will work in J2ME environments. Though these implementations may not be able to process the document type declaration, they still can work with known DTDs by using this function.
    Please notes: The given value is used literally as replacement text and it corresponds to declaring entity in DTD that has all special characters escaped: left angle bracket is replaced with <, ampersnad with & and so on.
    Note: The given value is the literal replacement text and must not contain any other entity reference (if it contains any entity reference there will be no further replacement).
    Note: The list of pre-defined entity names will always contain standard XML entities such as amp (&), lt (<), gt (>), quot ("), and apos ('). Those cannot be redefined by this method!
    
    Specified by:
    
    defineEntityReplacementText in interface XmlPullParser
    
    Throws:

  - getNamespaceCount
```
public int getNamespaceCount(int depth)
                      throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    Returns the numbers of elements in the namespace stack for the given depth. If namespaces are not enabled, 0 is returned.
    NOTE: when parser is on END_TAG then it is allowed to call this function with getDepth()+1 argument to retrieve position of namespace prefixes and URIs that were declared on corresponding START_TAG.
    NOTE: to retrieve lsit of namespaces declared in current element:
```
       XmlPullParser pp = ...
       int nsStart = pp.getNamespaceCount(pp.getDepth()-1);
       int nsEnd = pp.getNamespaceCount(pp.getDepth());
       for (int i = nsStart; i < nsEnd; i++) {
          String prefix = pp.getNamespacePrefix(i);
          String ns = pp.getNamespaceUri(i);
           // ...
      }
 
```
    Specified by:
    
    getNamespaceCount in interface XmlPullParser
    
    Throws:

  - getNamespacePrefix
```
public String getNamespacePrefix(int pos)
                          throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Returns the namespace prefixe for the given position in the namespace stack. Default namespace declaration (xmlns='...') will have null as prefix. If the given index is out of range, an exception is thrown.
    Please note: when the parser is on an END_TAG, namespace prefixes that were declared in the corresponding START_TAG are still accessible although they are no longer in scope.
    
    Specified by:
    
    getNamespacePrefix in interface XmlPullParser
    
    Throws:
    
    XmlPullParserException
  - getNamespaceUri
```
public String getNamespaceUri(int pos)
                       throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Returns the namespace URI for the given position in the namespace stack If the position is out of range, an exception is thrown.
    NOTE: when parser is on END_TAG then namespace prefixes that were declared in corresponding START_TAG are still accessible even though they are not in scope
    
    Specified by:
    
    getNamespaceUri in interface XmlPullParser
    
    Throws:
    
    XmlPullParserException
  - getNamespace
```
public String getNamespace(String prefix)
```
    Description copied from interface: XmlPullParser
    Returns the URI corresponding to the given prefix, depending on current state of the parser.
    If the prefix was not declared in the current scope, null is returned. The default namespace is included in the namespace table and is available via getNamespace (null).
    This method is a convenience method for
```
  for (int i = getNamespaceCount(getDepth ())-1; i >= 0; i--) {
   if (getNamespacePrefix(i).equals( prefix )) {

```
public int getDepth()
```
    Description copied from interface: XmlPullParser
    Returns the current depth of the element. Outside the root element, the depth is 0. The depth is incremented by 1 when a start tag is reached. The depth is decremented AFTER the end tag event was observed.

  - getLineNumber
```
public int getLineNumber()
```
    Description copied from interface: XmlPullParser
    
    Returns the current line number, starting from 1. When the parser does not know the current line number or can not determine it, -1 is returned (e.g. for WBXML).
    
    Specified by:
    
    getLineNumber in interface XmlPullParser

    Specified by:
    
    getColumnNumber in interface XmlPullParser

  - isWhitespace
```
public boolean isWhitespace()
                     throws XmlPullParserException
```
    Description copied from interface: XmlPullParser
    
    Checks whether the current TEXT event contains only whitespace characters. For IGNORABLE_WHITESPACE, this is always true. For TEXT and CDSECT, false is returned when the current event text contains at least one non-white space character. For any other event type an exception is thrown.
    Please note: non-validating parsers are not able to distinguish whitespace and ignorable whitespace, except from whitespace outside the root element. Ignorable whitespace is reported as separate event, which is exposed via nextToken only.

  - getText
```
public String getText()
```
    Description copied from interface: XmlPullParser
    
    Returns the text content of the current event as String. The value returned depends on current event type, for example for TEXT event it is element content (this is typical case when next() is used). See description of nextToken() for detailed description of possible returned values for different types of events.
    NOTE: in case of ENTITY_REF, this method returns the entity replacement text (or null if not available). This is the only case where getText() and getTextCharacters() return different values.

  - getTextCharacters
```
public char[] getTextCharacters(int[] holderForStartAndLength)
```
    Description copied from interface: XmlPullParser
    
    Returns the buffer that contains the text of the current event, as well as the start offset and length relevant for the current event. See getText(), next() and nextToken() for description of possible returned values.
    Please note: this buffer must not be modified and its content MAY change after a call to next() or nextToken(). This method will always return the same value as getText(), except for ENTITY_REF. In the case of ENTITY ref, getText() returns the replacement text and this method returns the actual input buffer containing the entity name. If getText() returns null, this method returns null as well and the values returned in the holder array MUST be -1 (both start and length).
    
    Specified by:
    
    getTextCharacters in interface XmlPullParser
    
    Parameters:
    holderForStartAndLength - Must hold an 2-element int array into which the start offset and length values will be written.
    
    Returns:
    char buffer that contains the text of the current event (null if the current event has no text associated).

  - getNamespace
```
public String getNamespace()
```
    Description copied from interface: XmlPullParser
    
    Returns the namespace URI of the current element. The default namespace is represented as empty string. If namespaces are not enabled, an empty String ("") is always returned. The current event must be START_TAG or END_TAG; otherwise, null is returned.

  - getName
```
public String getName()
```
    Description copied from interface: XmlPullParser
    
    For START_TAG or END_TAG events, the (local) name of the current element is returned when namespaces are enabled. When namespace processing is disabled, the raw name is returned. For ENTITY_REF events, the entity name is returned. If the current event is not START_TAG, END_TAG, or ENTITY_REF, null is returned.
    Please note: To reconstruct the raw element name when namespaces are enabled and the prefix is not null, you will need to add the prefix and a colon to localName..

  - getPrefix
```
public String getPrefix()
```
    Description copied from interface: XmlPullParser

    Description copied from interface: XmlPullParser
    If current event is START_TAG then if next element is TEXT then element content is returned or if next event is END_TAG then empty string is returned, otherwise exception is thrown. After calling this function successfully parser will be positioned on END_TAG.
    The motivation for this function is to allow to parse consistently both empty elements and elements that has non empty content, for example for input:
    1. <tag>foo</tag>
    2. <tag></tag> (which is equivalent to <tag/> both input can be parsed with the same code:
      p.nextTag() p.requireEvent(p.START_TAG, "", "tag"); String content = p.nextText(); p.requireEvent(p.END_TAG, "", "tag");
      This function together with nextTag make it very easy to parse XML that has no mixed content.
      Essentially it does this
      if(getEventType() != START_TAG) { throw new XmlPullParserException( "parser must be on START_TAG to read next text", this, null); } int eventType = next(); if(eventType == TEXT) { String result = getText(); eventType = next(); if(eventType != END_TAG) { throw new XmlPullParserException( "event TEXT it must be immediately followed by END_TAG", this, null); } return result; } else if(eventType == END_TAG) { return ""; } else { throw new XmlPullParserException( "parser must be on START_TAG or TEXT to read text", this, null); }

    Description copied from interface: XmlPullParser
    This method works similarly to next() but will expose additional event types (COMMENT, CDSECT, DOCDECL, ENTITY_REF, PROCESSING_INSTRUCTION, or IGNORABLE_WHITESPACE) if they are available in input.
    If special feature FEATURE_XML_ROUNDTRIP (identified by URI: http://xmlpull.org/v1/doc/features.html#xml-roundtrip) is enabled it is possible to do XML document round trip ie. reproduce exectly on output the XML input using getText(): returned content is always unnormalized (exactly as in input). Otherwise returned content is end-of-line normalized as described XML 1.0 End-of-Line Handling and. Also when this feature is enabled exact content of START_TAG, END_TAG, DOCDECL and PROCESSING_INSTRUCTION is available.
    Here is the list of tokens that can be returned from nextToken() and what getText() and getTextCharacters() returns:
    START_DOCUMENT
    null
    END_DOCUMENT
    null
    START_TAG
    null unless FEATURE_XML_ROUNDTRIP enabled and then returns XML tag, ex: <tag attr='val'>
    END_TAG
    null unless FEATURE_XML_ROUNDTRIP id enabled and then returns XML tag, ex: </tag>
    TEXT
    return element content.
    Note: that element content may be delivered in multiple consecutive TEXT events.
    IGNORABLE_WHITESPACE
    return characters that are determined to be ignorable white space. If the FEATURE_XML_ROUNDTRIP is enabled all whitespace content outside root element will always reported as IGNORABLE_WHITESPACE otherise rteporting is optional.
    Note: that element content may be delevered in multiple consecutive IGNORABLE_WHITESPACE events.
    CDSECT
    return text inside CDATA (ex. 'fo<o' from <!CDATA[fo<o]]>)
    PROCESSING_INSTRUCTION
    if FEATURE_XML_ROUNDTRIP is true return exact PI content ex: 'pi foo' from <?pi foo?> otherwise it may be exact PI content or concatenation of PI target, space and data so for example for <?target data?> string "target data" may be returned if FEATURE_XML_ROUNDTRIP is false.
    COMMENT
    return comment content ex. 'foo bar' from 
    ENTITY_REF
    getText() MUST return entity replacement text if PROCESS_DOCDECL is false otherwise getText() MAY return null, additionally getTextCharacters() MUST return entity name (for example 'entity_name' for &entity_name;).
    NOTE: this is the only place where value returned from getText() and getTextCharacters() are different
    NOTE: it is user responsibility to resolve entity reference if PROCESS_DOCDECL is false and there is no entity replacement text set in defineEntityReplacementText() method (getText() will be null)
    NOTE: character entities (ex.  ) and standard entities such as & < > " ' are reported as well and are not reported as TEXT tokens but as ENTITY_REF tokens! This requirement is added to allow to do roundtrip of XML documents!
    DOCDECL
    if FEATURE_XML_ROUNDTRIP is true or PROCESS_DOCDECL is false then return what is inside of DOCDECL for example it returns:
    " titlepage SYSTEM "http://www.foo.bar/dtds/typo.dtd" [<!ENTITY % active.links "INCLUDE">]"
    
    for input document that contained:
    <!DOCTYPE titlepage SYSTEM "http://www.foo.bar/dtds/typo.dtd" [<!ENTITY % active.links "INCLUDE">]>
    otherwise if FEATURE_XML_ROUNDTRIP is false and PROCESS_DOCDECL is true then what is returned is undefined (it may be even null)
    NOTE: there is no gurantee that there will only one TEXT or IGNORABLE_WHITESPACE event from nextToken() as parser may chose to deliver element content in multiple tokens (dividing element content into chunks)
    NOTE: whether returned text of token is end-of-line normalized is depending on FEATURE_XML_ROUNDTRIP.
    NOTE: XMLDecl (<?xml ...?>) is not reported but its content is available through optional properties (see class description above).
