ProcInstImpl

public ProcInstImpl(int nameCode,
 String content)

Method Details

getNameCode

public int getNameCode()

Get the nameCode of the node. This is used to locate the name in the NamePool

Specified by:

getNameCode in interface NodeInfo

Overrides:

getNameCode in class NodeImpl

Returns:

an integer name code, which may be used to obtain the actual node name from the name pool. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

• allocate
• getFingerprint

getStringValue

public String getStringValue()

Description copied from interface: NodeInfo

Return the string value of the node as defined in the XPath data model.

The interpretation of this depends on the type of node. For an element it is the accumulated character content of the element, including descendant elements.

This method returns the string value as if the node were untyped. Unlike the string value accessor in the XPath 2.0 data model, it does not report an error if the element has a complex type, instead it returns the concatenation of the descendant text nodes as it would if the element were untyped.

Returns:

the string value of the node

See Also:

• Item.getStringValueCS()

getTypedValue

public SequenceIterator getTypedValue()

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

Specified by:

getTypedValue in interface Item<NodeInfo>

Overrides:

getTypedValue in class NodeImpl

Returns:

an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.

atomize

public Value atomize()

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

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

See Also:

• 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 NodeInfo

Specified by:

getSystemId in interface Source

Specified by:

getSystemId in interface SourceLocator

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 NodeInfo

Specified by:

getLineNumber in interface SourceLocator

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,
 int 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-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

rename

public void rename(NodeName newNameCode)

Rename this node

Specified by:

rename in interface MutableNodeInfo

Overrides:

rename in class NodeImpl

Parameters:

newNameCode - the NamePool code of the new name

replaceStringValue

public void replaceStringValue(CharSequence stringValue)

Replace the string-value of this node

Parameters:

stringValue - the new string value
