Overview

A node extension for `pair` nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all `pair` nodes within RuboCop.

Instance Method Details

#colon?Boolean

Checks whether the `pair` uses a colon delimiter.

# File 'lib/rubocop/ast/node/pair_node.rb', line 26

def colon?
  loc.operator.is?(COLON)
end

#delimiter(with_spacing = false) ⇒ String

Returns the delimiter of the `pair` as a string. Returns `=>` for a colon delimited `pair` and `:` for a hash rocket delimited `pair`.
