Overview

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

Instance Method Details

#lambda? ⇒ Boolean

Checks whether this is a lambda. Some versions of parser parses non-literal lambdas as a method send.

Returns:

  • (Boolean) —

    whether this method is a lambda

# File 'lib/rubocop/ast/node/send_node.rb', line 24

def lambda?
  parent && parent.block_type? && method?(:lambda)
end

#negation_method? ⇒ Boolean

Checks whether this is a negation method, i.e. ‘!` or keyword `not`.

Returns:

  • (Boolean) —

    whether this method is a negation method

# File 'lib/rubocop/ast/node/send_node.rb', line 16

def negation_method?
  keyword_bang? || keyword_not?
end

#stabby_lambda? ⇒ Boolean

Checks whether this is a stabby lambda. e.g. ‘-> () {}`

Returns:

  • (Boolean) —

    whether this method is a staby lambda
