  NodeImpl
      ParentNodeImpl

All Implemented Interfaces:

Source, SourceLocator, FingerprintedNode, Item, NodeInfo, ValueRepresentation

Direct Known Subclasses:

ElementImpl, LazyDocument

public abstract class ParentNodeImpl
extends NodeImpl

Represents any node that can have children. Important note: when comparing for a Saxon upgrade, this code is kind of a mix between net.sf.saxon.tinytree.TinyParentNodeImpl and net.sf.saxon.tree.ParentNodeImpl.

ParentNodeImpl

public ParentNodeImpl()

Method Detail

hasChildNodes

public final boolean hasChildNodes()

Description copied from class: NodeImpl

Determine whether the node has any children.

Specified by:

hasChildNodes in interface NodeInfo

Overrides:

hasChildNodes in class NodeImpl

Returns:

true if the node has any children, false if the node has no children.

enumerateChildren

public final AxisIterator enumerateChildren(NodeTest test)

iterateAxis

public AxisIterator iterateAxis(byte axisNumber)

Description copied from class: NodeImpl

Return an enumeration over the nodes reached by the given axis from this node

Specified by:

iterateAxis in interface NodeInfo

Overrides:

iterateAxis in class NodeImpl

Parameters:

axisNumber - The axis to be iterated over

Returns:

an AxisIterator that scans the nodes reached by the axis in turn.

iterateAxis

public AxisIterator iterateAxis(byte axisNumber,
                                NodeTest nodeTest)

Description copied from class: NodeImpl

Return an enumeration over the nodes reached by the given axis from this node

Specified by:

iterateAxis in interface NodeInfo

Overrides:

iterateAxis in class NodeImpl

Parameters:

axisNumber - The axis to be iterated over

nodeTest - A pattern to be matched by the returned nodes

Returns:

an AxisIterator that scans the nodes reached by the axis in turn.

getFirstChild

public NodeInfo getFirstChild()

Get first child (DOM method)

Overrides:

getFirstChild in class NodeImpl

Returns:

the first child node of this node, or null if it has no children

getLastChild

public NodeInfo getLastChild()

The last child of this Node, or null if none.

Overrides:

getLastChild in class NodeImpl

Returns:

null

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.

Returns:

the accumulated character content of the element, including descendant elements.

getStringValueCS

public CharSequence getStringValueCS()

Description copied from class: NodeImpl

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String.

Specified by:

getStringValueCS in interface Item

Specified by:

getStringValueCS in interface ValueRepresentation

Overrides:

getStringValueCS in class NodeImpl
