Constructor Detail

VirtualUntypedCopy

protected VirtualUntypedCopy(NodeInfo base)

Protected constructor: create a virtual copy of a node

Parameters:

base - the node to be copied

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 copyOptions,
                 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

copyOptions - a selection of the options defined in CopyOptions

locationId - Identifies the location of the instruction

Throws:

XPathException

makeCopier

protected VirtualCopy.VirtualCopier makeCopier(AxisIterator axis,
                                               VirtualCopy newParent,
                                               NodeInfo root)

Create an iterator that makes and returns virtual copies of nodes on the original tree

Overrides:

makeCopier in class VirtualCopy

Parameters:

axis - the axis to be navigated

newParent - the parent of the nodes in the new virtual tree (may be null)

root - the root of the virtual tree

Returns:

the iterator that does the copying
