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 lib/prism/node.rb, line 10646
def self.type
  :integer_node

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 lib/prism/node.rb, line 10652
def ===(other)
  other.is_a?(IntegerNode) &&
    (flags === other.flags) &&
    (value === other.value)
end

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 10558
def accept(visitor)
  visitor.visit_integer_node(self)
end

def child_nodes: () -> Array[nil | Node]

# File lib/prism/node.rb, line 10563

  []
end

Also aliased as: deconstruct

def copy: (?flags: Integer, ?value: Integer, ?location: Location) -> IntegerNode

# File lib/prism/node.rb, line 10578
def copy(flags: self.flags, value: self.value, location: self.location)
  IntegerNode.new(source, flags, value, location)

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.
