Constructor Detail

AsyncEventHandler

public AsyncEventHandler()

Create an instance of AsyncEventHandler with default values for all parameters. This constructor is equivalent to AsyncEventHandler(null, null, null, null, null, false, null).

AsyncEventHandler

public AsyncEventHandler(SchedulingParameters scheduling,
                         ReleaseParameters release,
                         MemoryParameters memory,
                         MemoryArea area,
                         ProcessingGroupParameters group,
                         boolean nonheap,
                         Runnable logic)

Method Detail

setReleaseParameters

public void setReleaseParameters(ReleaseParameters release)
                          throws IllegalArgumentException,
                                 IllegalStateException

Description copied from interface: Schedulable

Sets the release parameters associated with this instance of Schedulable. Since this affects the constraints expressed in the release parameters of the existing schedulable objects, this may change the feasibility of the current system. This change becomes effective under conditions determined by the scheduler controlling the schedulable object. For instance, the change may be immediate or it may be delayed until the next release of the schedulable object. The different properties of the release parameters may take effect at different times. See the documentation for the scheduler for details.

Specified by:

setReleaseParameters in interface Schedulable

Parameters:

release - A ReleaseParameters object which will become the release parameters associated with this after the method call, and take effect as determined by the associated scheduler. If null, the default value is governed by the associated scheduler (a new object is created if the default value is not null). (See PriorityScheduler.)

Throws:

IllegalArgumentException - Never throwed for the moment.

java.lang.IllegalThreadStateException - Never throwed for the moment.

IllegalStateException

setSchedulingParameters

public void setSchedulingParameters(SchedulingParameters scheduling)
                             throws IllegalArgumentException

Description copied from interface: Schedulable

Sets the scheduling parameters associated with this instance of Schedulable. Since this affects the scheduling parameters of the existing schedulable objects, this may change the feasibility of the current system. This change becomes effective under conditions determined by the scheduler controlling the schedulable object. For instance, the change may be immediate or it may be delayed until the next release of the schedulable object. See the documentation for the scheduler for details.

Specified by:

setSchedulingParameters in interface Schedulable

Parameters:

scheduling - A reference to the SchedulingParameters object. If null, the default value is governed by the associated scheduler (a new object is created if the default value is not null). (See PriorityScheduler.)

Throws:

IllegalArgumentException - Never throwed for the moment.

run

public final void run()

Description copied from interface: Runnable

When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

Specified by:

run in interface Runnable

Specified by:
