public class Timed
extends AsynchronouslyInterruptedException

Jamaica Real-Time Specification for Java class Timed.

Timed is a subclass of AsynchronouslyInterruptedException that permit the execution of code provided in an instance of Interruptible with a given time out. After the time out is reached, the code will be interrupted by throwing this instance of AsynchronouslyInterruptedException.

No memory allocation will be performed after the creation of this Timed instance, several invocation of doInterruptible may hence be performed without additional memory allocation.

Constructor Summary

Timed(HighResolutionTime time)
Constructor to create a new instance of Timed with the given time out.

Method Summary

boolean	doInterruptible(Interruptible logic) doInterruptible executes the run() method of the provided Interruptible logic with the time-out provided to the constructor of this Timed or set via resetTime.
void	resetTime(HighResolutionTime time) resetTime sets the time out for the next invocation of doInterruptible to a new value.

Constructor Detail

Timed

public Timed(HighResolutionTime time)
      throws IllegalArgumentException

Constructor to create a new instance of Timed with the given time out.

Parameters:

time - the timeout when the execution the Interruptible logic should be stopped.

Throws:

IllegalArgumentException - if time is null.

Method Detail

doInterruptible

public boolean doInterruptible(Interruptible logic)

doInterruptible executes the run() method of the provided Interruptible logic with the time-out provided to the constructor of this Timed or set via resetTime.

Overrides:

doInterruptible in class AsynchronouslyInterruptedException

Parameters:

logic - Contains the run() method that specifies the logic to be executed in an interruptible way.

Returns:

false iff this call failed since this Timed instance is currently running a call to doInterruptible for the current or a different thread.

Throws:

IllegalArgumentException - iff the provided logic parameter is null.

resetTime

public void resetTime(HighResolutionTime time)

resetTime sets the time out for the next invocation of doInterruptible to a new value.

Parameters:

time - the new time out. It may be null to keep the time out unchanged.
