Filter

1. Overview

The Filter can filter a message using a filter strategy. A filter strategy returns a boolean value. Based on this value and the value of the inverse attribute, either the message is passed along, or is sent to the discard flow .

The filter can be used as a simple router service .

The filter strategy will have to be defined in a Bean.

In the table below, you will find an explanation of these properties.
