ProcInstImpl

public ProcInstImpl(int nameCode,
                    java.lang.String content)
Method Detail

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 java.lang.String getStringValue()
Description copied from interface: NodeInfo
Return the string value of the node. This is normally the string value as defined in the XPath data model, except that no distinction is made between strings and untyped atomic values.

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()

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(java.lang.String uri,
                        int lineNumber)
Set the system ID and line number


getSystemId

public java.lang.String getSystemId()
Get the system ID for the entity containing this node.

Specified by:
getSystemId in interface javax.xml.transform.Source
Specified by:
getSystemId in interface javax.xml.transform.SourceLocator
Specified by:
getSystemId in interface NodeInfo
Overrides:
getSystemId in class NodeImpl
Returns:
the System Identifier of the entity in the source document containing the node, or null if not known.

getLineNumber

public int getLineNumber()
Get the line number of the node within its source entity

Specified by:
getLineNumber in interface javax.xml.transform.SourceLocator
Specified by:
getLineNumber in interface NodeInfo
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 whichNamespaces,
                 boolean copyAnnotations,
                 int locationId)
          throws XPathException
Copy this node to a given outputter

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 NodeInfo.NO_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.ALL_NAMESPACES
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:
XPathException

getTarget

public java.lang.String getTarget()
The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction.


getData

public java.lang.String getData()
The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?> .
