org.codehaus.groovy.classgen.asm
[Java] Class ExpressionAsVariableSlot

java.lang.Object
  org.codehaus.groovy.ast.ASTNode
      org.codehaus.groovy.ast.AnnotatedNode
          org.codehaus.groovy.ast.expr.Expression
              org.codehaus.groovy.classgen.BytecodeExpression
                  org.codehaus.groovy.classgen.asm.ExpressionAsVariableSlot

public class ExpressionAsVariableSlot
extends BytecodeExpression

Helper class that takes an Expression and if visited will load it normally, storing the result in a helper variable, which then can be requested after the visit is completed. A copy of the variable will stay on the stack. Subsequent visits will load the stored value instead of visiting the expression again
