Method Detail

makeVirtualUntypedCopy

public static VirtualCopy makeVirtualUntypedCopy(NodeInfo original,
                                                 NodeInfo root)
Public factory method: create an untyped virtual copy of a node

Parameters:
original - the node to be copied
root - the root of the tree
Returns:
the virtual copy.

getTypeAnnotation

public int getTypeAnnotation()
Get the type annotation of this node, if any.

Specified by:
getTypeAnnotation in interface NodeInfo
Overrides:
getTypeAnnotation in class VirtualCopy
Returns:
the type annotation of the node.

Type

atomize

public Value atomize()
              throws XPathException
Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.

Specified by:
atomize in interface NodeInfo
Overrides:
atomize in class VirtualCopy
Returns:
the typed value. If requireSingleton is set to true, the result will always be an AtomicValue. In other cases it may be a Value representing a sequence whose items are atomic values.
Throws:
XPathException
Since:
8.5

getTypedValue

public SequenceIterator getTypedValue()
                               throws XPathException
Get the typed value of the item

Specified by:
getTypedValue in interface Item
Overrides:
getTypedValue in class VirtualCopy
Returns:
the typed value of the item. In general this will be a sequence
Throws:
XPathException - where no typed value is available, e.g. for an element with complex content

copy

public void copy(Receiver out,
                 int whichNamespaces,
                 boolean copyAnnotations,
                 int locationId)
          throws XPathException
Description copied from class: VirtualCopy
Copy this node to a given outputter

Specified by:
copy in interface NodeInfo
Overrides:
copy in class VirtualCopy
Parameters:
out - the Receiver to which the node should be copied
whichNamespaces - in the case of an element, controls which namespace nodes should be copied. Values are NO_NAMESPACES, LOCAL_NAMESPACES, ALL_NAMESPACES
copyAnnotations - indicates whether the type annotations of element and attribute nodes should be copied
locationId - Identifies the location of the instruction that requested this copy. Pass zero if no other information is available
Throws:
XPathException
