Method Detail

getNodeName

public NodeName getNodeName()

Get the name of the node. Returns null for an unnamed node

Overrides:

getNodeName in class NodeImpl

Returns:

the name of the node

getStringValue

public String getStringValue()

Description copied from interface: Item

Get the value of the item as a string. For nodes, this is the string value of the node as defined in the XPath 2.0 data model, except that all nodes are treated as being untyped: it is not an error to get the string value of a node with a complex type. For atomic values, the method returns the result of casting the atomic value to a string.

If the calling code can handle any CharSequence, the method Item.getStringValueCS() should be used. If the caller requires a string, this method is preferred.

Returns:

the string value of the item

See Also:

Item.getStringValueCS()

atomize

public AtomicSequence atomize()

Get the typed value of this node. Returns the string value, as an instance of xs:string

Specified by:

atomize in interface Item

Specified by:

atomize in interface NodeInfo

Overrides:

atomize in class NodeImpl

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.

getNodeKind

public final int getNodeKind()

Description copied from interface: NodeInfo

Get the kind of node. This will be a value such as Type.ELEMENT or Type.ATTRIBUTE. There are seven kinds of node: documents, elements, attributes, text, comments, processing-instructions, and namespaces.

Returns:

an integer identifying the kind of node. These integer values are the same as those used in the DOM

Type

setLocation

public void setLocation(String uri,
               int lineNumber)

Set the system ID and line number

Parameters:

uri - the system identifier

lineNumber - the line number

getSystemId

public String getSystemId()

Get the system ID for the entity containing this node.

Specified by:

getSystemId in interface Source

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface Location

Specified by:

getSystemId in interface NodeInfo

Specified by:

getSystemId in interface Locator

Overrides:

getSystemId in class NodeImpl

Returns:

the system identifier

getLineNumber

public int getLineNumber()

Get the line number of the node within its source entity

Specified by:

getLineNumber in interface SourceLocator

Specified by:

getLineNumber in interface Location

Specified by:

getLineNumber in interface NodeInfo

Specified by:

getLineNumber in interface Locator

Overrides:

getLineNumber in class NodeImpl

Returns:

the line number of the node in its original source document; or -1 if not available

copy

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

Copy this node to a given outputter

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 zero, indicates that the location information is not available

Throws:

XPathException - if any downstream error occurs

rename

public void rename(NodeName newNameCode)

Rename this node

Specified by:

rename in interface MutableNodeInfo

Overrides:

rename in class NodeImpl

Parameters:

newNameCode - the new name

replaceStringValue

public void replaceStringValue(CharSequence stringValue)

Replace the string-value of this node

Parameters:

stringValue - the new string value
