Method Detail

initialise

public final void initialise()
                      throws InitialisationException

Specified by:

initialise in interface Initialisable

Overrides:

initialise in class AbstractTransformer

Throws:

InitialisationException

doInitialise

protected void doInitialise()
                     throws InitialisationException

Throws:

InitialisationException

getResultHolder

protected static AbstractXmlTransformer.ResultHolder getResultHolder(Class<?> desiredClass)

Parameters:

desiredClass - Java class representing the desired format

Returns:

Callback interface representing the desiredClass - or null if the return class isn't supported (or is null).

convertToText

@Deprecated
protected String convertToText(Object obj)
                        throws Exception

Deprecated. Replaced by convertToText(Object obj, String ouputEncoding)

Converts an XML in-memory representation to a String

Parameters:

obj - Object to convert (could be byte[], String, DOM, DOM4J)

Returns:

String including XML header using default (UTF-8) encoding

Throws:

TransformerFactoryConfigurationError - On error

TransformerException - On error

TransformerException

Exception

convertToText

protected String convertToText(Object obj,
                   String outputEncoding)
                        throws Exception

Converts an XML in-memory representation to a String using a specific encoding. If using an encoding which cannot represent specific characters, these are written as entities, even if they can be represented as a Java String.

Parameters:

obj - Object to convert (could be byte[], String, DOM, or DOM4J Document). If the object is a byte[], the character encoding used MUST match the declared encoding standard, or a parse error will occur.

outputEncoding - Name of the XML encoding to use, e.g. US-ASCII, or null for UTF-8

Returns:

String including XML header using the specified encoding

Throws:

TransformerFactoryConfigurationError - On error

TransformerException - On error

TransformerException

Exception

convertToBytes

protected String convertToBytes(Object obj,
                    String outputEncoding)
                         throws Exception

Converts an XML in-memory representation to a String using a specific encoding.

Parameters:

obj - Object to convert (could be byte[], String, DOM, or DOM4J Document). If the object is a byte[], the character encoding used MUST match the declared encoding standard, or a parse error will occur.

outputEncoding - Name of the XML encoding to use, e.g. US-ASCII, or null for UTF-8

Returns:

String including XML header using the specified encoding

Throws:

TransformerFactoryConfigurationError - On error

TransformerException - On error

TransformerException

Exception

writeToStream

protected void writeToStream(Object obj,
                 String outputEncoding,
                 OutputStream output)
                      throws Exception

Throws:

Exception
