public class ExpansionApplier

extends VariableBinder

The class ExpansionApplier is an evaluator of each objects of ParseTree family. Each methods in this class is invoked from the class EvaluationShuttle.

The method evaluateDown() is invoked before evaluating the children of the parse tree object, and evaluateUp() is invoked after the evaluation.

For a class P and a object p statically typed as P, the parts in source code each expantion will be applied are:

• Allocation new P()
• ArrayAllocation new P[expr]
• MethodCall P.m(), p.m()
• FieldRead P.f, p.f as a right side value
• FieldWrite P.f = expr, p.f = expr
• ArrayAccess ap[expr] for P[] ap;
• Expression p

in feature version:

• CastExpression (P) expr including implicit cast
• CastedExpression (Q) p including implicit cast
