# class Prism::Dispatcher

The dispatcher class fires events for nodes that are found while walking an AST to all registered listeners. It’s useful for performing different types of analysis on the AST while only having to walk the tree once.

To use the dispatcher, you would first instantiate it and register listeners for the events you’re interested in:

    class OctalListener
      def on_integer_node_enter(node)
        if node.octal? && !node.slice.start_with?("0o")
          warn("Octal integers should be written with the 0o prefix")
        end
      end
    end

    listener = OctalListener.new
    dispatcher = Prism::Dispatcher.new
    dispatcher.register(listener, :on_integer_node_enter)

Then, you can walk any number of trees and dispatch events to the listeners:

    result = Prism.parse("001 + 002 + 003")
    dispatcher.dispatch(result.value)

Optionally, you can also use ‘#dispatch_once` to dispatch enter and leave events for a single node without recursing further down the tree. This can be useful in circumstances where you want to reuse the listeners you already have registers but want to stop walking the tree at a certain point.

    integer = result.value.statements.body.first.receiver.receiver
    dispatcher.dispatch_once(integer)
