Constant Field Values

Constructor Detail

DefaultExecutive

public DefaultExecutive()

Default construct to be used as ExecutiveSource.

DefaultExecutive

public DefaultExecutive(ThreadFactoryManufacturer threadFactoryManufacturer)

Instantiate to use as Executive.

Parameters:

threadFactoryManufacturer - ThreadFactoryManufacturer.

Method Detail

getExecutionStrategyMap

public java.util.Map<java.lang.String,java.util.concurrent.ThreadFactory[]> getExecutionStrategyMap()

Obtains the ExecutionStrategy instances by name.

Returns:

ExecutionStrategy instances by name.

loadSpecification

protected void loadSpecification(AbstractExecutiveSource.SpecificationContext context)

Description copied from class: AbstractExecutiveSource

Overridden to load specification.

Specified by:

loadSpecification in class AbstractExecutiveSource

Parameters:

context - AbstractExecutiveSource.SpecificationContext.

createExecutive

public Executive createExecutive(ExecutiveSourceContext context)
                          throws java.lang.Exception

Description copied from interface: ExecutiveSource

Creates the Executive.

Specified by:

createExecutive in interface ExecutiveSource

Parameters:

context - ExecutiveSourceContext.

Returns:

Executive.

Throws:

java.lang.Exception - If fails to configure the ExecutiveSource.

getExcutionStrategies

public ExecutionStrategy[] getExcutionStrategies()

Description copied from interface: Executive

Obtains the ExecutionStrategy strategies.

Specified by:

getExcutionStrategies in interface Executive

Returns:

ExecutionStrategy instances.

startManaging

public void startManaging(ExecutiveStartContext context)
                   throws java.lang.Exception

Description copied from interface: Executive

Starts managing the OfficeFloor.

Specified by:

startManaging in interface Executive

Parameters:

context - ExecutiveStartContext.

Throws:

java.lang.Exception - If fails to start managing.

createExecutor

public java.util.concurrent.Executor createExecutor(ProcessIdentifier processIdentifier)

Description copied from interface: Executive

Creates an Executor that MUST execute the Runnable in a different Thread to the caller.

This is used in various places within OfficeFloor:

• By ManagedFunction in executing Runnable in another Thread
• To avoid stack over flow issues, the stack call chain is broken by invoking further FunctionState delegation in another Thread. This allows further depth to a thread stack than offered by a single Thread.

Specified by:

createExecutor in interface Executive

Parameters:

processIdentifier - ProcessIdentifier of ProcessState requiring the Executor.

Returns:

Executor that will execute Runnable instances in a different Thread to caller.

schedule

public void schedule(ProcessIdentifier processIdentifier,
                     long delay,
                     java.lang.Runnable runnable)

Description copied from interface: Executive

Schedules the Runnable to execute so many milliseconds in the future.

Note that the Executive may determine the ProcessState complete and not execute the Runnable.

Specified by:

schedule in interface Executive

Parameters:

processIdentifier - ProcessIdentifier of the ProcessState requiring the scheduled execution.

delay - Delay in milliseconds to execute the Runnable.

runnable - Runnable to execute.

stopManaging

public void stopManaging()
                  throws java.lang.Exception

Description copied from interface: Executive

Stops managing the OfficeFloor.

Specified by:

stopManaging in interface Executive

Throws:

java.lang.Exception - If fails to stop managing.

schedule

public void schedule(long delay,
                     java.lang.Runnable runnable)

Description copied from interface: BackgroundScheduler

Schedules the Runnable to be executed after the delay.

Specified by:

schedule in interface BackgroundScheduler

Parameters:

delay - Delay in milliseconds.

runnable - Runnable.

getExecutionStrategyName

public java.lang.String getExecutionStrategyName()

Description copied from interface: ExecutionStrategy

Obtains the name of the ExecutionStrategy.

Specified by:

getExecutionStrategyName in interface ExecutionStrategy

Returns:

Name of the ExecutionStrategy.

getThreadFactories

public java.util.concurrent.ThreadFactory[] getThreadFactories()

Description copied from interface: ExecutionStrategy

Obtains the ThreadFactory instances for the various Thread instances of this ExecutionStrategy.

Specified by:

getThreadFactories in interface ExecutionStrategy

Returns:

ThreadFactory instances.
