Method Detail

load

XMLDocument load(String inputString)

Creates and returns an XMLDocument from the input String. By default does not perform XSD validation. Same as load(new StringReader(inputString), null, null);

Parameters:

inputString - specifies the String to read from

Returns:

the new XMLDocument loaded

Throws:

RuntimeException - for errors in XML parsing or implementation-specific validation.

load

XMLDocument load(InputStream inputStream)
                 throws IOException

Creates and returns an XMLDocument from the inputStream. The InputStream will be closed after reading. By default does not perform XSD validation. Same as load(inputStream, null, null);

Parameters:

inputStream - specifies the InputStream to read from

Returns:

the new XMLDocument loaded

Throws:

IOException - for stream exceptions.

RuntimeException - for errors in XML parsing or implementation-specific validation.

load

XMLDocument load(InputStream inputStream,
                 String locationURI,
                 Object options)
                 throws IOException

Creates and returns an XMLDocument from the inputStream. The InputStream will be closed after reading. By default does not perform XSD validation.

Parameters:

inputStream - specifies the InputStream to read from

locationURI - specifies the URI of the document for relative schema locations

options - implementation-specific options.

Returns:

the new XMLDocument loaded

Throws:

IOException - for stream exceptions.

RuntimeException - for errors in XML parsing or implementation-specific validation.

load

XMLDocument load(Reader inputReader,
                 String locationURI,
                 Object options)
                 throws IOException

Creates and returns an XMLDocument from the inputReader. The InputStream will be closed after reading. By default does not perform XSD validation.

Parameters:

inputReader - specifies the Reader to read from

locationURI - specifies the URI of the document for relative schema locations

options - implementation-specific options.

Returns:

the new XMLDocument loaded

Throws:

IOException - for stream exceptions.

RuntimeException - for errors in XML parsing or implementation-specific validation.

load

XMLDocument load(Source inputSource,
                 String locationURI,
                 Object options)
                 throws IOException

Creates and returns an XMLDocument from the inputSource. The InputSource will be closed after reading. By default does not perform XSD validation.

Parameters:

inputSource - specifies the Source to read from

locationURI - specifies the URI of the document for relative schema locations

options - implementation-specific options.

Returns:

the new XMLDocument loaded

Throws:

IOException - for stream exceptions.

RuntimeException - for errors in XML parsing or implementation-specific validation.

save

String save(DataObject dataObject,
            String rootElementURI,
            String rootElementName)

Returns the DataObject saved as an XML document with the specified root element. Same as StringWriter stringWriter = new StringWriter(); save(createDocument(dataObject, rootElementURI, rootElementName), stringWriter, null); stringWriter.toString();

Parameters:

dataObject - specifies DataObject to be saved

rootElementURI - the Target Namespace URI of the root XML element

rootElementName - the Name of the root XML element

Returns:

the saved XML document as a string

Throws:

IllegalArgumentException - if the dataObject tree is not closed or has no container.

save

void save(DataObject dataObject,
          String rootElementURI,
          String rootElementName,
          OutputStream outputStream)
          throws IOException

Saves the DataObject as an XML document with the specified root element. Same as save(createDocument(dataObject, rootElementURI, rootElementName), outputStream, null);

Parameters:

dataObject - specifies DataObject to be saved

rootElementURI - the Target Namespace URI of the root XML element

rootElementName - the Name of the root XML element

outputStream - specifies the OutputStream to write to.

Throws:

IOException - for stream exceptions.

IllegalArgumentException - if the dataObject tree is not closed or has no container.

save

void save(XMLDocument xmlDocument,
          OutputStream outputStream,
          Object options)
          throws IOException

Serializes an XMLDocument as an XML document into the outputStream. If the DataObject's Type was defined by an XSD, the serialization will follow the XSD. Otherwise the serialization will follow the format as if an XSD were generated as defined by the SDO specification. The OutputStream will be flushed after writing. Does not perform validation to ensure compliance with an XSD.

Parameters:

xmlDocument - specifies XMLDocument to be saved

outputStream - specifies the OutputStream to write to.

options - implementation-specific options.

Throws:

IOException - for stream exceptions.

IllegalArgumentException - if the dataObject tree is not closed or has no container.

save

void save(XMLDocument xmlDocument,
          Writer outputWriter,
          Object options)
          throws IOException

Serializes an XMLDocument as an XML document into the outputWriter. If the DataObject's Type was defined by an XSD, the serialization will follow the XSD. Otherwise the serialization will follow the format as if an XSD were generated as defined by the SDO specification. The OutputStream will be flushed after writing. Does not perform validation to ensure compliance with an XSD.

Parameters:

xmlDocument - specifies XMLDocument to be saved

outputWriter - specifies the Writer to write to.

options - implementation-specific options.

Throws:

IOException - for stream exceptions.

IllegalArgumentException - if the dataObject tree is not closed or has no container.

save

void save(XMLDocument xmlDocument,
          Result outputResult,
          Object options)
          throws IOException

Serializes an XMLDocument as an XML document into the outputResult in a serialization technology independent format (as specified in javax.xml.transform). The OutputResult will be flushed after writing. Does not perform validation to ensure compliance with an XSD.

Parameters:

xmlDocument - specifies XMLDocument to be saved

options - implementation-specific options.

Throws:

IOException - for stream exceptions.
