class RuboCop::AST::CaseMatchNode
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
.
Public Instance Methods
Returns an array of all the when branches in the `case` statement.
@return [Array<Node, nil>] an array of the bodies of the `in` branches and the `else` (if any). Note that these bodies could be nil.
# File lib/rubocop/ast/node/case_match_node.rb, line 38 def branches bodies = in_pattern_branches.map(&:body) if else? # `empty-else` node sets nil because it has no body. else_branch.empty_else_type? ? bodies.push(nil) : bodies.push(else_branch) end bodies end
@deprecated Use `in_pattern_branches.each`
# File lib/rubocop/ast/node/case_match_node.rb, line 19 def each_in_pattern(&block) return in_pattern_branches.to_enum(__method__) unless block in_pattern_branches.each(&block) self end
Checks whether this case statement has an `else` branch.
@return [Boolean] whether the `case` statement has an `else` branch
# File lib/rubocop/ast/node/case_match_node.rb, line 59 def else? !loc.else.nil? end
Returns the else branch of the `case` statement, if any.
@return [Node] the else branch node of the `case` statement @return [EmptyElse] the empty else branch node of the `case` statement @return [nil] if the case statement does not have an else branch.
# File lib/rubocop/ast/node/case_match_node.rb, line 52 def else_branch node_parts[-1] end
Returns an array of all the `in` pattern branches in the `case` statement.
@return [Array<InPatternNode>] an array of `in_pattern` nodes
# File lib/rubocop/ast/node/case_match_node.rb, line 30 def in_pattern_branches node_parts[1...-1] end
Returns the keyword of the `case` statement as a string.
@return [String] the keyword of the `case` statement
# File lib/rubocop/ast/node/case_match_node.rb, line 14 def keyword 'case' end
