All Implemented Interfaces:

Iterable<XdmItem>

public class XdmJNode
extends XdmItem

This class represents a JNode in the XDM data model. An XdmJNode is an XdmItem, and is therefore an XdmValue in its own right, and may also participate as one item within a sequence value.

An XdmJNode is implemented as a wrapper around an object of type JNode.

The XdmJNode interface exposes basic properties of the JNode, such as its parent, its selector, its position, and its contained value.

Since:

13.0

Constructor Details

XdmJNode

public XdmJNode(JNode node)

Construct an XdmJNode as a wrapper around an existing JNode object. This constructor is intended primarily for system use.

Parameters:

node - the JNode object to be wrapped. This can be retrieved using the getUnderlyingValue() method.

Method Details

getContent

public XdmValue getContent()

Get the content property of the JNode.

Returns:

the value of the content property

getUnderlyingValue

public JNode getUnderlyingValue()

Get the underlying implementation object representing the JNode. This method allows access to lower-level Saxon functionality, including classes and methods that offer no guarantee of stability across releases.

Overrides:

getUnderlyingValue in class XdmItem

Returns:

the underlying implementation object representing the JNode

getSelector

public XdmAtomicValue getSelector()

Get the selector of the JNode, as an XdmAtomicValue

Returns:

the selector of the JNode. Returns null for a root JNode; otherwise the key value for a JNode representing an entry in a map, or the 1-based index for a JNode representing a member of an array.

getPosition

public int getPosition()

Get the position of the JNode, as an integer

Returns:

the integer of the JNode. Returns -1 for a root JNode; otherwise the position of the JNode within a sequence-valued parent (normally 1, since array members and map entry values are usually singletons)
