Detailed Description

Base class for active objects.

Constructor & Destructor Documentation

Task()

SmartACE::Task::Task

(

Smart::IComponent *

component = 0

)

Constructor.

~Task()

virtual SmartACE::Task::~Task ( )

virtual

Destructor.

Member Function Documentation

setCpuAffinity()

int SmartACE::Task::setCpuAffinity ( const int &  cpuCore )

protected

setSchedParams()

int SmartACE::Task::setSchedParams ( const ACE_Sched_Params &  sched_params )

protected

sleep_for()

virtual void SmartACE::Task::sleep_for ( const Smart::Duration &  rel_time )

protectedvirtual

Blocks execution of the calling thread during the span of time specified by rel_time.

Thread-sleeping is sometimes platform-specific. This method encapsulates the blocking sleep. Calling this method blocks the execution of the calling thread for a time specified by rel_time.

Parameters

rel_time

relative time duration for the thread to sleep

start() [1/2]

virtual int SmartACE::Task::start ( )

virtual

Creates and starts a new thread (if not yet started)

Reimplemented in SmartACE::ThreadQueueQueryHandler< RequestType, AnswerType >.

start() [2/2]

virtual int SmartACE::Task::start ( const ACE_Sched_Params &  sched_params, const int &  cpuAffinity = -1  )

virtual

control method to start the internal thread using given scheduling parameters

stop()

virtual int SmartACE::Task::stop ( const bool  wait_till_stopped = true )

virtual

Closes currently active thread (if it was started before)

Reimplemented in SmartACE::ThreadQueueQueryHandler< RequestType, AnswerType >.

svc()

virtual int SmartACE::Task::svc ( void  )

protectedvirtual

implements ACE_Task<ACE_MT_SYNCH>

test_canceled()

virtual bool SmartACE::Task::test_canceled ( )

protectedvirtual

Tests whether the thread has been signaled to stop.

This method allows to implement cooperative thread stopping.
