Habari STOMP Client for RabbitMQ is a high-level, object-oriented STOMP client library for Delphi and Free Pascal which provides access to the RabbitMQ free open source message broker.
language
With this library, developers can build integrated solutions, connecting cross language clients and protocols, using the peer-to-peer or the publish-and-subscribe communication model.favorite_border
It is easy to configure and provides a high-level API and programming model, based on connections, sessions, destinations, message producers, and message consumers.filter_list
The library uses the STOMP Streaming Text Oriented Messaging Protocol for its communication with the message broker, which uses an interoperable wire format.The STOMP specification does not prescribe what kinds of destinations a broker must support, instead the value of the destination header in SEND and MESSAGE frames is broker-specific. The RabbitMQ STOMP adapter supports a number of different destination types:
All destination types may be used with Habari STOMP Client for RabbitMQ. For details, see API documentation at IMQContext (for the simplified API) or ISession.html (for the classic API).
Habari STOMP Client libraries support broker-specific extensions of the STOMP specification. Most of them can be accessed with the same client side code across all broker versions.
timer
By default, a message never expires. If a message will become obsolete after a certain period, however, you may want to set an expiration time for the message.
traffic
A client can specify a priority for each message it sends. Message priorities affect the order in which the messages are delivered to the consumers.
storage
Brokers support reliable messaging by allowing messages to be persisted so that they can be recovered if there is failure which kills the broker.
pause_circle_outline
Even if the client which created the durable subscription is not online, he can still get a copy of all the messages sent to the topic when he comes back online.
import_export
Binary and text messages can be exchanged between STOMP and non-STOMP clients. (Object and map messages are exchanged as text messages)
sync
Temporary destinations are typically used to receive response messages in a request/response messaging exchange.
