Defined in:
lib/rubocop/ast/node/array_node.rb

Overview

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

Instance Method Details

#bracketed? ⇒ Boolean

Checks whether the ‘array` literal is delimited by either percent or square brackets

brackets

Returns:

  • (Boolean) —

    whether the array is enclosed in percent or square

# File 'lib/rubocop/ast/node/array_node.rb', line 60

def bracketed?
  square_brackets? || percent_literal?
end

#each_value(&block) ⇒ Object

Deprecated.

Use ‘values.each` (a.k.a. `children.each`)

  self
end

#percent_literal? ⇒ Boolean #percent_literal?(type) ⇒ Boolean

Checks whether the ‘array` literal is delimited by percent brackets.

Overloads:

  • #percent_literal? ⇒ Boolean

    Check for any percent literal.

  • #percent_literal?(type) ⇒ Boolean

    Check for percent literal of type ‘type`.

    Parameters:

    • type (Symbol) —

      an optional percent literal type

Returns:

  • (Boolean) —

    whether the array is enclosed in percent brackets

end

#square_brackets? ⇒ Boolean

Checks whether the ‘array` literal is delimited by square brackets.

Returns:
