## net.sf.saxon.expr
Class EagerLetExpression

    java.lang.Object
      net.sf.saxon.expr.ComputedExpression
          net.sf.saxon.expr.Assignation
              net.sf.saxon.expr.LetExpression
                  net.sf.saxon.expr.EagerLetExpression

All Implemented Interfaces:
  Binding, Container, Expression, InstructionInfoProvider, java.io.Serializable, javax.xml.transform.SourceLocator, TailCallReturner

public class EagerLetExpression
extends LetExpression

An EagerLetExpression is the same as a LetExpression except that the variable is evaluated using eager evaluation rather than lazy evaluation. This is used when performing diagnostic tracing.
