Module: RuboCop::AST::ConditionalNode

Included in:
CaseNode, IfNode, UntilNode, WhileNode
Defined in:
lib/rubocop/ast/node/mixin/conditional_node.rb

Overview

Common functionality for nodes that have conditions: ‘if`, `while`, `until`, `case`. This currently doesn’t include ‘when` nodes, because they have multiple conditions, and need to be checked for that.
