protected property

Automatically matches up template strings by name to output handlers.

A handler can either be a string, which represents a method name of the helper, or it can be a closure or callable object.

A handler takes 3 parameters:

  1. the value to be filtered
  2. the name of the helper method that triggered the handler
  3. the array of options passed to the _render()

These handlers are shared among all helper objects, and are automatically triggered whenever a helper method renders a template string (using _render()) and a key which is to be embedded in the template string matches an array key of a corresponding handler.
