[Java] Class VariableExpressionReplacer

  • org.codehaus.groovy.transform.tailrec.VariableExpressionReplacer
public class VariableExpressionReplacer
extends CodeVisitorSupport

Tool for replacing VariableExpression instances in an AST by other VariableExpression instances. Regardless of a real change taking place in nested expressions, all considered expression (trees) will be replaced. This could be optimized to accelerate compilation.

Within

TailRecursive:
it is used - to swap the access of method args with the access to iteration variables - to swap the access of iteration variables with the access of temp vars

@Override public void visitAssertStatement(AssertStatement statement)

@Override public void visitBinaryExpression(BinaryExpression expression)

It's the only Expression type in which replacing is considered. That's an abuse of the class, but I couldn't think of a better way.
