Parameters: element the parent element of the namespace node nscode the namespace code, representing the prefix and URI of the namespace binding position maintains document order among namespace nodes for the same element
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.
Since: 8.5
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())
Parameters: out the Receiver to which the node should be copied whichNamespaces in the case of an element, controls which namespace nodes should be copied. Values are NamespaceNodeImpl, NamespaceNodeImpl, NamespaceNodeImpl copyAnnotations indicates whether the type annotations of element and attribute nodes should be copied locationId If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be a LocationCopier
Throws: net.sf.saxon.trans.XPathException
Parameters: other the node to be compared with this node
Returns: true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree.
Since: 8.7 Previously, the effect of the equals() method was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics. It is safer to use isSameNodeInfo() for this reason. The equals() method has been defined because it is useful in contexts such as a Java Set or HashMap.
Parameters: buffer buffer to hold a string that uniquely identifies this node, across all documents.
Parameters: fingerprint The fingerprint of the attribute name
Returns: the attribute value if it exists or null if not
Returns: the base URI of the node
Returns: the column number of the node in its original source document; or -1 if not available
Parameters: buffer 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.
Returns: An array of integers representing the namespace declarations and undeclarations present on
this element. For a node other than an element, return null. Otherwise, the returned array is a
sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The
top half word of each namespace code represents the prefix, the bottom half represents the URI.
If the bottom half is zero, then this is a namespace undeclaration rather than a declaration.
The XML namespace is never included in the list. If the supplied array is larger than required,
then the first unused entry will be set to -1.
For a node other than an element, the method returns null.
Returns: The display name of this node. For a node with no name, return an empty string.
Returns: the DocumentInfo representing the containing document. If this node is part of a tree that does not have a document node as its root, return null.
Returns: an integer fingerprint; two nodes with the same fingerprint have the same expanded QName
Returns: the line number of the node in its original source document; or -1 if not available
Returns: the local part of the name. For an unnamed node, returns "". Unlike the DOM interface, this returns the full name in the case of a non-namespaced name.
Returns: an integer name code, which may be used to obtain the actual node name from the name pool
See Also: allocate
getFingerprint
Returns: the namepool
Returns: an integer identifying the kind of node. These integer values are the same as those used in the DOM
See Also: Type
Returns: the parent of this node; null if this node has no parent
Returns: The prefix of the name of the node.
Returns: the NodeInfo representing the top-level ancestor of this node. This will not necessarily be a document node
Returns: the string value of the node
Returns: the System Identifier of the entity in the source document containing the node, or null if not known. Note this is not the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot.
Returns: the type annotation of the node.
See Also: Type
Returns: the typed value of the item. In general this will be a sequence
Throws: net.sf.saxon.trans.XPathException where no typed value is available, e.g. for an element with complex content
Returns: The URI of the namespace of this node. Since the name of a namespace node is always an NCName (the namespace prefix), this method always returns "".
Returns: True if the node has one or more children
Since: 8.7 Previously, the effect of the equals() and hashCode() methods was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics.
Returns: true if the node is an ID
Returns: true if the node is an IDREF or IDREFS element or attribute
Returns: true if the node has the is-nilled property
Parameters: other the node to be compared with this node
Returns: true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree.
Parameters: axisNumber an integer identifying the axis; one of the constants defined in class net.sf.saxon.om.Axis
Returns: an AxisIterator that scans the nodes reached by the axis in turn.
Throws: UnsupportedOperationException if the namespace axis is requested and this axis is not supported for this implementation.
See Also: Axis
Parameters: axisNumber an integer identifying the axis; one of the constants defined in class net.sf.saxon.om.Axis nodeTest A pattern to be matched by the returned nodes; nodes that do not match this pattern are not included in the result
Returns: a NodeEnumeration that scans the nodes reached by the axis in turn.
Throws: UnsupportedOperationException if the namespace axis is requested and this axis is not supported for this implementation.

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.
Parameters: systemId The system identifier as a URL string.
