Public Class Methods

new(source, node_id, location, flags, name, name_loc, operator_loc, value) click to toggle source

Initialize a new OptionalParameterNode node.

# File prism/node.rb, line 12555
def initialize(source, node_id, location, flags, name, name_loc, operator_loc, value)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc
  @operator_loc = operator_loc
  @value = value
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

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 12646
def ===(other)
  other.is_a?(OptionalParameterNode) &&
    (flags === other.flags) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
end
