class Prism::NumberedParametersNode

def initialize: (Integer maximum, Location location) -> void

# File prism/node.rb, line 13890
def initialize(source, maximum, location)
  @source = source
  @location = location
  @maximum = maximum
end

Similar to type, this method returns a symbol that you can use for splitting on the type of the node without having to do a long === chain. Note that like type, it will still be slower than using == for a single class, but should be faster in a case statement or an array comparison.

def self.type: () -> Symbol

# File prism/node.rb, line 13961
def self.type
  :numbered_parameters_node
end

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 13967
def ===(other)
  other.is_a?(NumberedParametersNode) &&
    (maximum === other.maximum)
end

def copy: (?maximum: Integer, ?location: Location) -> NumberedParametersNode

end

Sometimes you want to check an instance of a node against a list of classes to see what kind of behavior to perform. Usually this is done by calling ‘[cls1, cls2].include?(node.class)` or putting the node into a case statement and doing `case node; when cls1; when cls2; end`. Both of these approaches are relatively slow because of the constant lookups, method calls, and/or array allocations.

Instead, you can call type, which will return to you a symbol that you can use for comparison. This is faster than the other approaches because it uses a single integer comparison, but also because if you’re on CRuby you can take advantage of the fact that case statements with all symbol keys will use a jump table.
