new (source, node_id, location, flags, name, name_loc, operator_loc)

Source

# File lib/prism/node.rb, line 11416

  @source = source
  @node_id = node_id

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 11521
def ===(other)
  other.is_a?(KeywordRestParameterNode) &&
    (flags === other.flags) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

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