Package net.sf.saxon.expr

Class CurrentItemExpression

java.lang.Object

net.sf.saxon.expr.Expression

net.sf.saxon.expr.ContextItemExpression

net.sf.saxon.expr.CurrentItemExpression

All Implemented Interfaces:

ExportAgent, Locatable, IdentityComparable, Traceable

public class CurrentItemExpression
extends ContextItemExpression

The expression is generated when compiling the current() function in XSLT. It differs from the ContextItemExpression "." only in the error code that is returned when there is no context item.
