@SCJAllowed(value=LEVEL_1)
public class AperiodicParameters
extends ReleaseParameters

SCJ supports no detection of minimum inter-arrival time violations, therefore only aperiodic parameters are needed. Hence the RTSJ SporadicParameters class is absent.
Deadline miss detection is supported.
The RTSJ supports a queue for storing the arrival of release events in order to enable bursts of events to be handled. This queue is of length 1 in SCJ. The RTSJ also enables different responses to the queue overflowing. In SCJ the overflow behavior is to overwrite the pending release event if there is one.

Constructor Detail

AperiodicParameters

public AperiodicParameters()

APR updated Construct a new AperiodicParameters object within the current memory area with no deadline detection facility.

AperiodicParameters

public AperiodicParameters(RelativeTime deadline,
                   AperiodicEventHandler missHandler)

Construct a new AperiodicParameters object within the current memory area.

Parameters:

deadline - is an offset from the release time by which the release should finish. A null deadline indicates that there is no deadline.

missHandler - is the AperiodicEventHandler to be released if the handler misses its deadline. A null parameter indicates that no handler should be released.
