Class XPointerExpression

java.lang.Object
  org.eclipse.cosmos.rm.validation.internal.reference.XPointerExpression

public class XPointerExpression
extends java.lang.Object

This class is used to represent an XPointer expression that can be evaluated. Instances of this class should be obtained by compiling a string representation of the XPointer expression: XPointer.compile(String)

Field Summary

protected static byte	BARE_NAME_TYPE Indicates a bare name type
protected static byte	CHILD_SEQUENCE_TYPE Indicates a child sequence type
protected static byte	FULL_XPOINTER_TYPE Indicates a full xpointer type

Constructor Summary

protected

XPointerExpression(byte type) The visibility of the constructor is limited.

Method Summary

void	addChildSequence(int child) Add a child sequence to this expression
void	addScheme(IXScheme scheme) Add a scheme to this expression
java.lang.Object	evaluate(java.lang.Object context) Evaluates this expression using the context that is passed in
java.lang.String	getBareName()
int[]	getChildSequence() Retuns a copy of the child sequence
java.util.List	getScheme() Returns the schemes associated with this XPointer expression
byte	getType()
void	setBareName(java.lang.String bareName)
