TypeStrippedNode
protected TypeStrippedNode(NodeInfo node, TypeStrippedNode parent)

Method Detail
-
makeWrapper
public static TypeStrippedNode makeWrapper(NodeInfo node, TypeStrippedDocument docWrapper, TypeStrippedNode parent)
Factory method to wrap a node with a wrapper that implements the Saxon NodeInfo interface.- Parameters:
node
- The underlying nodedocWrapper
- The wrapper for the document node (must be supplied)parent
- The wrapper for the parent of the node (null if unknown)- Returns:
- The new wrapper for the supplied node
-
makeWrapper
public VirtualNode makeWrapper(NodeInfo node, VirtualNode parent)
Factory method to wrap a node with a VirtualNode- Specified by:
makeWrapper
in interfaceWrappingFunction
- Parameters:
node
- The underlying nodeparent
- The wrapper for the parent of the node (null if unknown)- Returns:
- The new wrapper for the supplied node
-
atomize
public Value atomize() throws XPathException
Get the typed value. The result of this method will always be consistent with the methodItem.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 interfaceNodeInfo
- Overrides:
atomize
in classAbstractVirtualNode
- 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
- if the node has no typed value, for example if it is an element node with element-only content- Since:
- 8.5
-
getTypeAnnotation
public int getTypeAnnotation()
Get the type annotation- Specified by:
getTypeAnnotation
in interfaceNodeInfo
- Overrides:
getTypeAnnotation
in classAbstractVirtualNode
- Returns:
- untyped or untypedAtomic (the purpose of this class is to strip the type annotation)
-
getSchemaType
public SchemaType getSchemaType()
Get the type annotation- Specified by:
getSchemaType
in interfaceNodeInfo
- Overrides:
getSchemaType
in classAbstractVirtualNode
- Returns:
- the type annotation of the base node
-
isSameNodeInfo
public boolean isSameNodeInfo(NodeInfo other)
Determine whether this is the same node as another node.
Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)- Specified by:
isSameNodeInfo
in interfaceNodeInfo
- Overrides:
isSameNodeInfo
in classAbstractVirtualNode
- Parameters:
other
- the node to be compared with this node- Returns:
- true if this Node object and the supplied Node object represent the same node in the tree.
-
compareOrder
public int compareOrder(NodeInfo other)
Determine the relative position of this node and another node, in document order. The other node will always be in the same document.- Specified by:
compareOrder
in interfaceNodeInfo
- Overrides:
compareOrder
in classAbstractVirtualNode
- Parameters:
other
- The other node, whose position is to be compared with this node- Returns:
- -1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())
-
getParent
public NodeInfo getParent()
Get the NodeInfo object representing the parent of this node
-
iterateAxis
public AxisIterator iterateAxis(byte axisNumber)
Return an iteration over the nodes reached by the given axis from this node- Specified by:
iterateAxis
in interfaceNodeInfo
- Parameters:
axisNumber
- the axis to be used- Returns:
- a SequenceIterator that scans the nodes reached by the axis in turn.
- See Also:
Axis
-
getDocumentRoot
public DocumentInfo getDocumentRoot()
Get the root (document) node- Specified by:
getDocumentRoot
in interfaceNodeInfo
- Overrides:
getDocumentRoot
in classAbstractVirtualNode
- Returns:
- the DocumentInfo representing the containing document
-
copy
public void copy(Receiver out, int copyOptions, int locationId) throws XPathException
Copy this node to a given outputter (deep copy)- Specified by:
copy
in interfaceNodeInfo
- Parameters:
out
- the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.copyOptions
- a selection of the options defined inCopyOptions
locationId
- If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information- Throws:
XPathException
- if any downstream error occurs
