Overview
The platform's loopback binding can be used to send to other applications running in the same process. The loopback binding is often used for unit testing in which several applications may be launched in the same process for easy debugging.Two applications that connect to a loopback bus with the same name may exchange messages with one another.
Bus Descriptor Format
A loopback message bus can be configured via a descriptor string as follows which uses the address to indicate the loopback bus instance to which to connect followed by a list of provider properties.
loopback://<busname>&prop1=val1&propN=valN
An example bus descriptor for solace would like like:
loopback://<busname>&topic_starts_with_channel=false&set_bus_and_channel_on_receipt=true
DDL
In a DDL config file a solace bus can equivalently be configured in one two ways
Decomposed
The descriptor form is useful in cases where the descriptor name may be supplied as an external configuration property that is substituted at runtime, but defaults to loopback for testing:
