  - ### Method Detail

    - #### protected void addError(String msg, ASTNode expr)

      Reports an error back to the source unit.

      Parameters:
        `msg` - the error message
        `expr` - the expression that caused the error message.

    - #### protected String convertClosureToSource(ClosureExpression expression)

      Converts a ClosureExpression into the String source.

      Parameters:
        `expression` - a closure
      Returns:
        the source the closure was created from

    - #### protected abstract boolean handleTargetMethodCallExpression(MethodCallExpression call)

    - #### protected abstract boolean isBuildInvocation(MethodCallExpression call)

    - #### @Override
      public void visitMethodCallExpression(MethodCallExpression call)

      Attempts to find AstBuilder 'from code' invocations. When found, converts them into calls to the 'from string' approach.

      Parameters:
        `call` - the method call expression that may or may not be an AstBuilder 'from code' invocation.
