Includes:

AST::Processor::Mixin

Defined in:

lib/atp/processor.rb

Overview

The base processor, this provides a default handler for all node types and will not make any changes to the AST, i.e. an equivalent AST will be returned by the process method.

Child classes of this should be used to implement additional processors to modify or otherwise work with the AST.
