public class Child

extends UnImplNode

implements DOMOrder, SaxEventDispatch

Class representing a child node

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Field Detail

m_doc

protected DocumentImpl m_doc

Document Object

m_parent

protected Parent m_parent

This child's parent node

Constructor Detail

Child

public Child(DocumentImpl doc)

Constructor Child

Parameters:

doc - document object

Method Detail

setDoc

protected void setDoc(DocumentImpl doc)

Set the document object for this child

Parameters:

doc - document object

setParent

protected void setParent(Parent parent)

Set the parent of the node.

Parameters:

parent - this node's parent

isComplete

public boolean isComplete()

Return if this node has had all it's children added, i.e. if a endElement event has occured. An atomic node always returns true.

Returns:

true.

setComplete

public void setComplete(boolean isComplete)

Set that this node's child list is complete, i.e. an endElement event has occured. At this level, this method does nothing.

Parameters:

isComplete - true if this node has had all it's children added.

getTransformer

protected TransformerImpl getTransformer()

Get the Transformer object for this source tree.

Returns:

transformer object for this source tree

throwParseError

protected void throwParseError(java.lang.Exception e)

Throw a Parse Error exception

Parameters:

e - original exception

throwIfParseError

protected void throwIfParseError()

Throw a Parse Error exception if no exception was thrown yet

setUid

protected void setUid(int kIndex)

Set the UID (document order index).

Parameters:

kIndex - Index of this child.

getUid

public int getUid()

Get the UID (document order index).

Specified by:

getUid in interface DOMOrder

Returns:

Index of this child

getLevel

public short getLevel()

Get the depth level of this node in the tree.

Returns:

This child's level in the source tree

setLevel

public void setLevel(short level)

Get the depth level of this node in the tree.

Parameters:

level - This child's level in the source tree

getParentNode

public org.w3c.dom.Node getParentNode()

The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.

Returns:

This node's parent node.

Overrides:

getParentNode in class UnImplNode

getFirstChild

public org.w3c.dom.Node getFirstChild()

The first child of this node. If there is no such node, this returns null.

Returns:

This node's first child.

Overrides:

getFirstChild in class UnImplNode

getLastChild

public org.w3c.dom.Node getLastChild()

The last child of this node. If there is no such node, this returns null.

Returns:

This node's last child.

Overrides:

getLastChild in class UnImplNode

getPreviousSibling

public org.w3c.dom.Node getPreviousSibling()

The node immediately preceding this node. If there is no such node, this returns null.

Returns:

This node's previous sibling

Overrides:

getPreviousSibling in class UnImplNode

getNextSibling

public org.w3c.dom.Node getNextSibling()

The node immediately following this node. If there is no such node, this returns null.

Returns:

This node's next sibling.

Overrides:

getNextSibling in class UnImplNode

getOwnerDocument

public org.w3c.dom.Document getOwnerDocument()

The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.

Returns:

document object

Overrides:

getOwnerDocument in class UnImplNode

hasChildNodes

public boolean hasChildNodes()

This is a convenience method to allow easy determination of whether a node has any children.
