Method Detail

load

XMLDocument load(java.lang.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

the new XMLDocument loaded

Throws:

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

load

XMLDocument load(java.io.InputStream inputStream)

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:

java.io.IOException - for stream exceptions.

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

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

options - implementation-specific options.

Returns:

the new XMLDocument loaded

Throws:

java.io.IOException - for stream exceptions.

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

                 java.lang.Object options)
                 throws java.io.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:

java.io.IOException - for stream exceptions.

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

save

java.lang.String save(DataObject dataObject,
                      java.lang.String rootElementURI,
                      java.lang.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:

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

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

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.

java.io.IOException - for stream exceptions.

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

          java.lang.Object options)
          throws java.io.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:

java.io.IOException - for stream exceptions.

Parameters:

xmlDocument - specifies XMLDocument to be saved

outputResult - specifies Result to be saved

options - implementation-specific options.

Throws:

java.io.IOException - for stream exceptions.

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

XMLDocument createDocument(DataObject dataObject,
                           java.lang.String rootElementURI,
                           java.lang.String rootElementName)

Creates an XMLDocument with the specified XML rootElement for the DataObject.

Parameters:
