Class: RuboCop::AST::CaseMatchNode
- Includes:
- ConditionalNode
- Defined in:
- lib/rubocop/ast/node/case_match_node.rb
Overview
A node extension for ‘case_match` nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all `case_match` nodes within RuboCop.
