ParentNodeImpl is an implementation of a non-leaf node (specifically, an Element node
or a Document node)
addChild
public void addChild(NodeImpl node,
int index)
Add a child node to this node. For system use only. Note: normalizing adjacent text nodes
is the responsibility of the caller.
compact
public void compact(int size)
Compact the space used by this node
dropChildren
public void dropChildren()
Drop a branch of the tree. The target element remains in the tree, but its children are
disconnected from the parent. Unless there are other references to the children (e.g. in
a variable) they will be deleted from memory next time the garbage collector comes round.
enumerateChildren
public final AxisEnumeration enumerateChildren(NodeTest test)
Get an enumeration of the children of this node
getChildNodes
public final NodeList getChildNodes()
Return a NodeList
that contains all children of this node. If
there are no children, this is a NodeList
containing no
nodes.
- getChildNodes in interface NodeImpl
getFirstChild
public final Node getFirstChild()
Get the first child node of the element
- getFirstChild in interface NodeImpl
- the first child node of the required type, or null if there are no children
getLastChild
public final Node getLastChild()
Get the last child node of the element
- getLastChild in interface NodeImpl
- the last child of the element, or null if there are no children
getNodeValue
public String getNodeValue()
Get the node value as defined in the DOM. This is not the same as the XPath string-value.
- getNodeValue in interface AbstractNode
getNthChild
protected final NodeImpl getNthChild(int n)
Get the nth child node of the element (numbering from 0)
- the last child of the element, or null if there is no n'th child
getSequenceNumber
protected final long getSequenceNumber()
Get the node sequence number (in document order). Sequence numbers are monotonic but not
consecutive. In the current implementation, parent nodes (elements and roots) have a zero
least-significant word, while namespaces, attributes, text nodes, comments, and PIs have
the top word the same as their owner and the bottom half reflecting their relative position.
- getSequenceNumber in interface NodeImpl
getStringValue
public String getStringValue()
Return the string-value of the node, that is, the concatenation
of the character content of all descendent elements and text nodes.
- getStringValue in interface NodeInfo
- the accumulated character content of the element, including descendant elements.
removeChild
public void removeChild(int index)
Remove node at given index. Will always be followed by a renumberChildren().
renumberChildren
public void renumberChildren()
Renumber the children of a given parent node. For system use only
useChildrenArray
public void useChildrenArray(NodeImpl[] array)
Supply an array to be used for the array of children. For system use only.
