Annotation Type Unit

public @interface Unit

Represents an Function Unit in the sense of the Flow Design paradigm. It defines input ports for receiving data and output ports to forward computation results to other function units or for applying side effects.

Optional Element Summary

Optional Elements

Modifier and Type	Optional Element and Description
Port[]	inputPorts Defines on or more named Input Ports the function unit receives typed input data over from other function units. Each of the declared ports may be connected to other function unit's output ports using the wiring operator: other_fu.out -> this_fu.a. Each input port a message may be forwarded using the forward operator: this_fu.a <= message. For integration units an integrated function unit input port may be connected to this unit's input port forwarding input messages to those integrated function unit: this_fu.i -> integrated_fu.in.
Port[]	outputPorts Defines one or more named and typed Output Ports the computation results of this function unit are forwarded over to other function units or to be processed for side effects. o may be connected to other function unit's out ports using the wiring operator: this_fu.o -> other_fu.in. For integration units an integrated function unit output port may be connected to this unit's output port forwarding computation result messages of those unit to this function unit's output port: integrated_fu.out -> this_fu.o.

Element Detail

inputPorts

public abstract Port[] inputPorts

Defines on or more named Input Ports the function unit receives typed input data over from other function units.
Each of the declared ports may be connected to other function unit's output ports using the wiring operator: other_fu.out -> this_fu.a.
Each input port a message may be forwarded using the forward operator: this_fu.a <= message.
For integration units an integrated function unit input port may be connected to this unit's input port forwarding input messages to those integrated function unit: this_fu.i -> integrated_fu.in.

Default:

{}

outputPorts

public abstract Port[] outputPorts

Defines one or more named and typed Output Ports the computation results of this function unit are forwarded over to other function units or to be processed for side effects.
o may be connected to other function unit's out ports using the wiring operator: this_fu.o -> other_fu.in.
For integration units an integrated function unit output port may be connected to this unit's output port forwarding computation result messages of those unit to this function unit's output port: integrated_fu.out -> this_fu.o.

Default:
