java.lang.Objectnet.sf.saxon.om.VirtualCopy
This class represents a node that is a virtual copy of another node: that is, it behaves as a node that's the same as another node, but has different identity. It is implemented by means of a reference to the node of which it is a copy, but methods that are sensitive to node identity return a different result.

iterateAxis in interface NodeInfoaxisNumber - an integer identifying the axis; one of the constants
defined in class net.sf.saxon.om.Axis
java.lang.UnsupportedOperationException - if the namespace axis is
requested and this axis is not supported for this implementation.Axis
public AxisIterator iterateAxis(byte axisNumber,
NodeTest nodeTest)
iterateAxis in interface NodeInfoaxisNumber - an integer identifying the axis; one of the constants
defined in class net.sf.saxon.om.AxisnodeTest - A pattern to be matched by the returned nodes; nodes
that do not match this pattern are not included in the result
java.lang.UnsupportedOperationException - if the namespace axis is
requested and this axis is not supported for this implementation.Axispublic java.lang.String getAttributeValue(int fingerprint)
getAttributeValue in interface NodeInfofingerprint - The fingerprint of the attribute name
public NodeInfo getRoot()
getRoot in interface NodeInfopublic DocumentInfo getDocumentRoot()
getDocumentRoot in interface NodeInfopublic boolean hasChildNodes()
hasChildNodes in interface NodeInfopublic void generateId(FastStringBuffer buffer)
generateId in interface NodeInfobuffer - a buffer, to which will be appended
a string that uniquely identifies this node, across all
documents.public int getDocumentNumber()
getDocumentNumber in interface NodeInfo
public void copy(Receiver out,
int whichNamespaces,
boolean copyAnnotations,
int locationId)
throws XPathException
copy in interface NodeInfoout - the Receiver to which the node should be copiedwhichNamespaces - in the case of an element, controls
which namespace nodes should be copied. Values are NO_NAMESPACES,
LOCAL_NAMESPACES, ALL_NAMESPACEScopyAnnotations - indicates whether the type annotations
of element and attribute nodes should be copiedlocationId - Identifies the location of the instruction
that requested this copy. Pass zero if no other information is available
XPathException
public void sendNamespaceDeclarations(Receiver out,
boolean includeAncestors)
throws XPathException
sendNamespaceDeclarations in interface NodeInfoout - The relevant outputterincludeAncestors - True if namespaces declared on ancestor
XPathExceptionpublic int[] getDeclaredNamespaces(int[] buffer)
getDeclaredNamespaces in interface NodeInfobuffer - If this is non-null, and the result array fits in this buffer, then the result
may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
For a node other than an element, the method returns null.
public void setSystemId(java.lang.String systemId)
The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.
setSystemId in interface javax.xml.transform.SourcesystemId - The system identifier as a URL string.
public SequenceIterator getTypedValue()
throws XPathException
getTypedValue in interface ItemXPathException - where no typed value is available, e.g. for
an element with complex content
public Value atomize()
throws XPathException
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.
