## [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

  - ### Method Detail

    - #### public Closure<VariableExpression> getReplaceWith()

    - #### public Closure<Boolean> getWhen()

    - #### public void replaceIn(ASTNode root)

    - #### @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.
