new(source, node_id, location, flags, lparen_loc, value, rparen_loc, keyword_loc) click to toggle source

Initialize a new DefinedNode node.

# File prism/node.rb, line 5360
def initialize(source, node_id, location, flags, lparen_loc, value, rparen_loc, keyword_loc)
  @source = source
  @node_id = node_id

  @flags = flags
  @lparen_loc = lparen_loc
  @value = value
  @rparen_loc = rparen_loc
  @keyword_loc = keyword_loc
end

Public Instance Methods

===(other) click to toggle source

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

# File prism/node.rb, line 5472
def ===(other)
  other.is_a?(DefinedNode) &&
    (lparen_loc.nil? == other.lparen_loc.nil?) &&
    (value === other.value) &&
    (rparen_loc.nil? == other.rparen_loc.nil?) &&
    (keyword_loc.nil? == other.keyword_loc.nil?)
end
