Method Detail

getParent

public Element getParent()

Description copied from interface: Node

getParent returns the parent Element if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.

This method is an optional feature and may not be supported for all Node implementations.

Specified by:

getParent in interface Node

Overrides:

getParent in class AbstractNode

Returns:

the parent of this node or null if it is the root of the tree or the parent relationship is not supported.

setParent

public void setParent(Element parent)

Description copied from interface: Node

setParent sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.

This method should only be called from inside an Element implementation method and is not intended for general use.

Specified by:

setParent in interface Node

Overrides:

setParent in class AbstractNode

Parameters:

parent - is the new parent of this node.

getDocument

public Document getDocument()

Description copied from interface: Node

getDocument returns the Document that this Node is part of if this node supports the parent relationship.

This method is an optional feature and may not be supported for all Node implementations.

Specified by:

getDocument in interface Node

Overrides:

getDocument in class AbstractNode

Returns:

the document of this node or null if this feature is not supported or the node is not associated with a Document

setDocument

public void setDocument(Document document)

Description copied from interface: Node

setDocument sets the document of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.

This method should only be called from inside a Document implementation method and is not intended for general use.

Specified by:

setDocument in interface Node

Overrides:

setDocument in class AbstractNode

Parameters:

document - is the new document of this node.

supportsParent

public boolean supportsParent()

Description copied from interface: Node

supportsParent returns true if this node supports the parent relationship.

Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.

Specified by:

supportsParent in interface Node

Overrides:

supportsParent in class AbstractNode

Returns:

true if this node supports the parent relationship or false it is not supported

getQName

public QName getQName()

Description copied from interface: Element

Returns the QName of this element which represents the local name, the qualified name and the Namespace.

Returns:

the QName associated with this element

setQName

public void setQName(QName name)

Description copied from interface: Element

Sets the QName of this element which represents the local name, the qualified name and the Namespace.

Parameters:

name - is the QName to be associated with this element

clearContent

public void clearContent()

Description copied from interface: Branch

Clears the content for this branch, removing any Node instances this branch may contain.

setContent

public void setContent(java.util.List<Node> content)

Description copied from interface: Branch

Sets the contents of this branch as a List of Node instances.

Parameters:

content - is the list of nodes to use as the content for this branch.

setAttributes

public void setAttributes(java.util.List<Attribute> attributes)

Description copied from interface: Element

Sets the attributes that this element contains

Parameters:

attributes - DOCUMENT ME!

contentList

protected java.util.List<Node> contentList()

Description copied from class: AbstractBranch

DOCUMENT ME!

Specified by:

contentList in class AbstractBranch

Returns:

the internal List used to manage the content

attributeList

protected java.util.List<Attribute> attributeList()

Description copied from class: AbstractElement

DOCUMENT ME!

Specified by:

attributeList in class AbstractElement

Returns:

the internal List used to store attributes or creates one if one is not available

attributeList

protected java.util.List<Attribute> attributeList(int size)

Description copied from class: AbstractElement

DOCUMENT ME!

Specified by:

attributeList in class AbstractElement

Parameters:

size - DOCUMENT ME!

Returns:

the internal List used to store attributes or creates one with the specified size if one is not available

setAttributeList

protected void setAttributeList(java.util.List<Attribute> attributeList)
