class Prism::ForwardingSuperNode

def initialize: (block: BlockNode?, location: Location) -> void

# File lib/prism/node.rb, line 6764
def initialize(block, location)
  @block = block
  @location = location
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 inspect(inspector = NodeInspector.new)
  inspector << inspector.header(self)

    inspector << "└── block: ∅\n"

    inspector << block.inspect(inspector.child_inspector("    ")).delete_prefix(inspector.prefix)
  end

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.
