Method Detail

getLexicalHandler

public LexicalHandler getLexicalHandler()

setLexicalHandler

public void setLexicalHandler(LexicalHandler lexical)

getIndentStep

public int getIndentStep()

Deprecated. Only return the length of the indent string.

Return the current indent step.

Return the current indent step: each start tag will be indented by this number of spaces times the number of ancestors that the element has.

Returns:

The number of spaces in each indentation step, or 0 or less for no indentation.

setIndentStep(int)

setIndentStep

public void setIndentStep(int indentStep)

Deprecated. Should use the version that takes string.

Set the current indent step.

Parameters:

indentStep - The new indent step (0 or less for no indentation).

setIndentStep

public void setIndentStep(String s)

startElement

public void startElement(String uri,
                         String localName,
                         String qName,
                         Attributes atts)
                  throws SAXException

Write a start tag.

Each tag will begin on a new line, and will be indented by the current indent step times the number of ancestors that the element has.

The newline and indentation will be passed on down the filter chain through regular characters events.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class XMLFilterImpl

Parameters:

uri - The element's Namespace URI.

localName - The element's local name.

qName - The element's qualified (prefixed) name.

atts - The element's attribute list.

Throws:

SAXException - If there is an error writing the start tag, or if a filter further down the chain raises an exception.

See Also:

XMLWriter.startElement(String, String, String,Attributes)

endElement

public void endElement(String uri,
                       String localName,
                       String qName)
                throws SAXException

Write an end tag.

If the element has contained other elements, the tag will appear indented on a new line; otherwise, it will appear immediately following whatever came before.

The newline and indentation will be passed on down the filter chain through regular characters events.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class XMLFilterImpl

Parameters:

uri - The element's Namespace URI.

localName - The element's local name.

qName - The element's qualified (prefixed) name.

Throws:

SAXException - If there is an error writing the end tag, or if a filter further down the chain raises an exception.

XMLWriter.endElement(String, String, String)

                throws SAXException

Write a sequence of characters.

Specified by:

Overrides:

Parameters:
