Constructor Detail

TypeStrippedNode

protected TypeStrippedNode()

TypeStrippedNode

protected TypeStrippedNode(NodeInfo node,
                           TypeStrippedNode parent)

This constructor is protected: nodes should be created using the makeWrapper factory method

Parameters:

node - The node to be wrapped

parent - The StrippedNode that wraps the parent of this node

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 node

docWrapper - 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 interface WrappingFunction

Parameters:

node - The underlying node

parent - The wrapper for the parent of the node (null if unknown)

Returns:

The new wrapper for the supplied node

atomize

public AtomicSequence atomize()
                       throws XPathException

Get the typed value.

Specified by:

atomize in interface Item

Specified by:

atomize in interface NodeInfo

Overrides:

atomize in class AbstractVirtualNode

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

getSchemaType

public SchemaType getSchemaType()

Get the type annotation

Specified by:

getSchemaType in interface NodeInfo

Overrides:

getSchemaType in class AbstractVirtualNode

Returns:

the type annotation of the base node

equals

public boolean equals(java.lang.Object 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:

equals in interface NodeInfo

Overrides:

equals in class AbstractVirtualNode

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.

hashCode

public int hashCode()

The hashCode() method obeys the contract for hashCode(): that is, if two objects are equal (represent the same node) then they must have the same hashCode()

Specified by:

hashCode in interface NodeInfo

Overrides:

hashCode in class AbstractVirtualNode

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 interface NodeInfo

Overrides:

compareOrder in class AbstractVirtualNode

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

Specified by:

getParent in interface NodeInfo

Returns:

the parent of this node; null if this node has no parent

iterateAxis

public AxisIterator iterateAxis(int axisNumber)

Return an iteration over the nodes reached by the given axis from this node

Specified by:

iterateAxis in interface NodeInfo

Parameters:

axisNumber - the axis to be used

Returns:

a SequenceIterator that scans the nodes reached by the axis in turn.

AxisInfo

copy

public void copy(Receiver out,
                 int copyOptions,
                 Location locationId)
          throws XPathException

Copy this node to a given outputter (deep copy)

Specified by:

copy in interface NodeInfo

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 in CopyOptions

locationId - If non-null, identifies the location of the instruction that requested this copy. If null, indicates that the location information is not available

Throws:

XPathException - if any downstream error occurs

isNilled

public boolean isNilled()

Description copied from class: AbstractVirtualNode

Determine whether the node has the is-nilled property

Specified by:

isNilled in interface NodeInfo

Overrides:

isNilled in class AbstractVirtualNode

Returns:

true if the node has the is-nilled property
