Instance Method Details

#===(other) ⇒ Object

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

# File 'lib/prism/node.rb', line 11401

def ===(other)
  other.is_a?(KeywordHashNode) &&
    (flags === other.flags) &&
    (elements.length == other.elements.length) &&
    elements.zip(other.elements).all? { |left, right| left === right }
end

#accept(visitor) ⇒ Object

def accept: (Visitor visitor) -> void

# File 'lib/prism/node.rb', line 11344

def accept(visitor)
  visitor.visit_keyword_hash_node(self)

def comment_targets: () -> Array[Node | Location]

# File 'lib/prism/node.rb', line 11359
