All Implemented Interfaces:

Binding, Instr, Locatable, java.io.Serializable, javax.xml.transform.SourceLocator

Direct Known Subclasses:

Param, Variable

public abstract class DefiningVariable

extends GeneralVariable

implements Binding

This class defines common behaviour across the compiled instructions for xsl:variable and xsl:param. In particular, this class contains the method used to evaluate the variable.
