ikr.simlib.entities.Entity

ikr.simlib.entities.phases.Phase

All Implemented Interfaces:

ReflectionConstructable, ReflectionConstructable2<SimNode,Parameters>

Direct Known Subclasses:

StdPhase, UnitPhase

public abstract class Phase
extends Entity
implements ReflectionConstructable2<SimNode,Parameters>

The abstract base class Phase derived from Entity. The class StdPhase is used to model service units. The service time of UnitPhase (unit refers here to information unit) is proportional to the length specified in Message and therefore models a link with a fixed bandwidth. The service time of StdPhase is obtained independent of the length of a packet by a distribution.
In the following, the detailed characteristics are described:

- Phase is implemented with the help of Event and InputMessageHandler, private derivation.

- The time intervals of the events, that represent the end of service are determined with the help of a continuous distribution, that must be delivered as a reference with StdPhase upon constructor call.

- In StdPhase the distribution can be read by the parser.

- State of the phase (free or busy) decides if arriving messages at the input port can be accepted or not (class InputPort).

- Upon end of service the serviced message is sent to the succeeding service unit via the output port (class SynchronousOutputPort), whereby blocking must be avoided.
