Method Summary

void	accept(Visitor visitor) accept is the method used in the Visitor Pattern.
java.lang.String	asXML() asXML returns the textual XML representation of this node.
java.lang.String	getName() getName returns the name of this node.
short	getNodeType() Returns the code according to the type of node.
java.lang.String	getPath(Element context) Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c.
java.lang.String	getText() Returns the text format of the declarations if applicable, or the empty String
java.lang.String	getUniquePath(Element context) Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node.

AbstractDocumentType

public AbstractDocumentType()

Method Detail

getNodeType

public short getNodeType()

Description copied from interface: Node

Returns the code according to the type of node. This makes processing nodes polymorphically much easier as the switch statement can be used instead of multiple if (instanceof) statements.

Specified by:

getNodeType in interface Node

Overrides:

getNodeType in class AbstractNode

getName

public java.lang.String getName()

Description copied from interface: Node

getName returns the name of this node. This is the XML local name of the element, attribute, entity or processing instruction. For CDATA and Text nodes this method will return null.

Specified by:

getName in interface Node

Overrides:

getName in class AbstractNode

setName

public void setName(java.lang.String name)

Description copied from interface: Node

Sets the text data of this node or this method will throw an UnsupportedOperationException if it is read-only.

Specified by:

setName in interface Node

Overrides:

setName in class AbstractNode

getPath

public java.lang.String getPath(Element context)

Description copied from interface: Node

Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c. No indexing will be used to restrict the path if multiple elements with the same name occur on the path.

Specified by:

getPath in interface Node

Parameters:

context - is the parent context from which the relative path should start. If the context is null or the context is not an ancestor of this node then the path will be absolute and start from the document and so begin with the '/' character.

Returns:

the XPath expression relative to the given context which will return a nodeset containing at least this node.

getUniquePath

public java.lang.String getUniquePath(Element context)

Description copied from interface: Node

Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node. This method will use the XPath index operator to restrict the path if multiple elements with the same name occur on the path.

Specified by:

getUniquePath in interface Node

Parameters:

context - is the parent context from which the path should start. If the context is null or the context is not an ancestor of this node then the path will start from the document and so begin with the '/' character.

Returns:

the XPath expression relative to the given context which will return a nodeset containing just this node.

getText

public java.lang.String getText()

Returns the text format of the declarations if applicable, or the empty String

Specified by:

getText in interface Node

Overrides:

getText in class AbstractNode

toString

public java.lang.String toString()

asXML

public java.lang.String asXML()

Description copied from interface: Node

asXML returns the textual XML representation of this node.

Specified by:

asXML in interface Node

Returns:

the XML representation of this node

write

public void write(java.io.Writer writer)
           throws java.io.IOException

Description copied from interface: Node

write writes this node as the default XML notation for this node. If you wish to control the XML output (such as for pretty printing, changing the indentation policy etc.) then please use XMLWriter or its derivations.

Specified by:

write in interface Node

Overrides:

write in class AbstractNode

Throws:

java.io.IOException

accept

public void accept(Visitor visitor)

Description copied from interface: Node

accept is the method used in the Visitor Pattern.

Specified by:

accept in interface Node

Parameters:

visitor - is the visitor in the Visitor Pattern
