Programmable (Trigger) Listener

Routes within the eiConsole and eiPlatform can be programmatically invoked through a simple Java API.

These Listeners only have a name. This name will be used with the Triggerable Listener API to invoke this interface. The Listener name is also important for connecting routes together.

1. Advanced: At the Advanced tab, you can specify:

Initialize on trigger only: If enabled, Listener doesn’t start up until a trigger initializes it.
Allow command-line invocation: If enabled, Listener can be invoked using the CLI client application.

Restart on listening error: If enabled, Listener will be restarted after an error occurs.

FIFO Queue Name: The FIFO stuff enables a “First In, First Out” queuing mechanism between Listeners and Transports. If a “FIFO Queue Name” is provided, that name will be used as a key for a queue Transactions & will be pushed into before reaching a transport. They’ll be ordered in this queue according to when the Listener created them.

FIFO Queue Delay: It is the interval between updates/checks against that queue. Providing a queue name guarantees that is a given.

2. Transaction Logging – This tab allows us to enable transaction events logging. That data can be logged by a TransactionEventListener.

The Transaction Logging Enable checkbox allows transaction events originating from this listener to be logged by a TransactionEventListener.

Log Transaction Attribute – if enabled, logs transaction attributes.

Log Transaction Data – if enabled, logs transaction data body.

Log Transaction Data Base64 – if enabled, logs transaction data body as Base64.

4. Called By – this tab allows you to check if current route is called by a RouteToRoute transport and if so, by which one exactly.

Called By: the Routes called into this listener (if there are any).
