Public Class Methods

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

Initialize a new MatchPredicateNode node.

# File prism/node.rb, line 11257
def initialize(source, node_id, location, flags, value, pattern, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @value = value
  @pattern = pattern
  @operator_loc = operator_loc
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 11335
def ===(other)
  other.is_a?(MatchPredicateNode) &&
    (value === other.value) &&
    (pattern === other.pattern) &&
    (operator_loc.nil? == other.operator_loc.nil?)
