OpenWire

OpenWire is Apache’s cross language Wire Protocol to allow native access to ActiveMQ from a number of different languages and platforms. OpenWire is a binary protocol designed for working with message-oriented middleware. It is the native wire format of ActiveMQ.

OpenWire is an open source dataflow programming library that extends the functionality of Embarcadero Delphi and C++ Builder by providing pin type component properties.

Pins form the connections between the components. OpenWire defines 4 types of pins:

• SourcePin usually provides data. Can connect to one or more SinkPins and to one StatePin.

• SinkPin usually received data. Can be connected to one SourcePin.

• MultiSinkPin usually received data. Can be connected to one or more SourcePin.

• StatePin usually is used to share state between components. Can be connected to one or more StatePins or SinkPins, and to one SourcePin.
