Method Detail

setCanonicalizer

public void setCanonicalizer(Canonicalizer canon)

Description copied from interface: Serializer

Set the Canonicalizer object to use.

Specified by:

setCanonicalizer in interface Serializer

serialize

public String serialize(Element element)
                 throws Exception

Returns a String representation of the specified Element.

Refer also to comments about setup of format.

Parameters:

element - the Element to serialize.

Returns:

the String representation of the serilaized Element.

Throws:

Exception

serializeToByteArray

public byte[] serializeToByteArray(Element element)
                            throws Exception

Returns a byte[] representation of the specified Element.

Specified by:

serializeToByteArray in interface Serializer

Parameters:

element - the Element to serialize.

Returns:

the byte[] representation of the serilaized Element.

Throws:

Exception

serialize

public String serialize(NodeList content)
                 throws Exception

Returns a String representation of the specified NodeList.

This is a special case because the NodeList may represent a DocumentFragment. A document fragment may be a non-valid XML document (refer to appropriate description of W3C) because it my start with a non-element node, e.g. a text node.

The methods first converts the node list into a document fragment. Special care is taken to not destroy the current document, thus the method clones the nodes (deep cloning) before it appends them to the document fragment.

Refer also to comments about setup of format.

Parameters:

content - the NodeList to serialize.

Returns:

the String representation of the serialized NodeList.

Throws:

Exception

serializeToByteArray

public byte[] serializeToByteArray(NodeList content)
                            throws Exception

Returns a byte[] representation of the specified NodeList.

Specified by:

serializeToByteArray in interface Serializer

Parameters:

content - the NodeList to serialize.

Returns:

the byte[] representation of the serialized NodeList.

Throws:

Exception

canonSerialize

public String canonSerialize(Node node)
                      throws Exception

Parameters:

canonSerializeToByteArray

public byte[] canonSerializeToByteArray(Node node)
                                 throws Exception
