# Markdent::Role::FilterHandler(3pm)

A role for handlers which act as filters

## NAME

Markdent::Role::FilterHandler - A role for handlers which act as filters

## VERSION

version 0.40

## DESCRIPTION

This role implements behavior and interface for filtering handlers. A filter handler takes events and does something to some of them, and then passes them on to another handler.

## REQUIRED METHODS

- •

  `$handler`-\>filter\_event($event)

  This method will always be called with a single object which does the Markdent::Role::Event role.

  If this method returns a single event, it will be passed on to the next handler. If it does not return an event, the event is dropped from the stream.

## ATTRIBUTES

This role provides the following attributes:

### handler

This is a read-only attribute. It is an object which does the Markdent::Role::Handler role.

This is the handler to which the filter passes events after filtering.
