All Implemented Interfaces:

Serializable, SourceLocator, LocationProvider, SaxonLocator, InstructionInfo, Locator

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.
