Method Detail
-
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.- Overrides:
getSequenceNumber
in classNodeImpl
-
hasChildNodes
public final boolean hasChildNodes()
Determine if the node has any children.- Specified by:
hasChildNodes
in interfaceNodeInfo
- Overrides:
hasChildNodes
in classNodeImpl
- Returns:
true
if the node has any children,false
if the node has no children.
-
enumerateChildren
public final AxisIterator enumerateChildren(NodeTest test)
Get an enumeration of the children of this node- Parameters:
test
- A NodeTest to be satisfied by the child nodes, or null if all child node are to be returned
-
getFirstChild
public final NodeInfo getFirstChild()
Get the first child node of the element- Overrides:
getFirstChild
in classNodeImpl
- Returns:
- the first child node of the required type, or null if there are no children
-
getLastChild
public final NodeInfo getLastChild()
Get the last child node of the element- Overrides:
getLastChild
in classNodeImpl
- Returns:
- the last child of the element, or null if there are no children
-
getNthChild
protected final NodeImpl getNthChild(int n)
Get the nth child node of the element (numbering from 0)- Returns:
- the last child of the element, or null if there is no n'th child
-
getStringValue
public java.lang.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.
- See Also:
Item.getStringValueCS()
-
getStringValueCS
public java.lang.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 interfaceItem
- Specified by:
getStringValueCS
in interfaceValueRepresentation
- Overrides:
getStringValueCS
in classNodeImpl
- Returns:
- the string value of the item
- See Also:
Item.getStringValue()
-
useChildrenArray
public void useChildrenArray(NodeImpl[] array)
Supply an array to be used for the array of children. For system use only.
-
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
