Interface ImmediateController

All Known Implementing Classes:

ImmediateHelper

@Contract
public interface ImmediateController

This service is advertised when the Immediate service is put into the registry. The immediate service by default starts in the SUSPENDED state so that the Executor and other parameters can be set prior to the first Immediate service being started

Method Detail

getExecutor

java.util.concurrent.Executor getExecutor()

Returns the executor that is currently in use by the Immediate subsystem

Returns:

The current executor in use by the controller. Will not return null since a default executor is used and returned by this call even if setExecutor is called with null

setExecutor

void setExecutor(java.util.concurrent.Executor executor)
          throws java.lang.IllegalStateException

Sets the executor to be used by the Immediate subsystem. If set to null a default executor will be used. This may only be called when the Immediate service is suspended

Parameters:

executor - The executor to be used when scheduling work. If null a default executor implementation will be used

Throws:

java.lang.IllegalStateException - if this is called when the Immediate service is not in suspended state

getThreadInactivityTimeout

long getThreadInactivityTimeout()

Returns the time in milliseconds a thread will wait for new Immediate services before dying

Returns:

The time in milliseconds a thread will wait for new Immediate service before dying

setThreadInactivityTimeout

void setThreadInactivityTimeout(long timeInMillis)
                         throws java.lang.IllegalArgumentException

Sets the time in milliseconds a thread will wait for new Immediate services before dying

Parameters:

timeInMillis - The time in milliseconds a thread will wait for new Immediate service before dying

Throws:

java.lang.IllegalArgumentException - if timeInMillis is less than zero

getImmediateState

ImmediateController.ImmediateServiceState getImmediateState()

Returns the state the system is currently running under

Returns:

The current state of the ImmediateService

setImmediateState

void setImmediateState(ImmediateController.ImmediateServiceState state)

Sets the state the system is currently running under

Parameters:

state - The new state of the ImmediateService
