class Prism::AssocSplatNode

def initialize: (Prism::node? value, Location operator_loc, Location location) -> void

# File prism/node.rb, line 1186

  @operator_loc = operator_loc
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 1278
def self.type
  :assoc_splat_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 1284
def ===(other)
  other.is_a?(AssocSplatNode) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

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

def comment_targets: () -> Array[Node | Location]

# File prism/node.rb, line 1211

end

def compact_child_nodes: () -> Array

# File prism/node.rb, line 1204
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << value if value
  compact

  AssocSplatNode.new(source, value, operator_loc, location)

The location of the ‘**` operator.

# File prism/node.rb, line 1238

  location = @operator_loc
  return location if location.is_a?(Location)

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.
