Detailed Description

Thread calculations block.

Constructor & Destructor Documentation

dcf::ThreadCalcBlock::ThreadCalcBlock

(

const dcf::Manager &

manager

)

Constructor. Only ThreadManager provides correct working.

virtual dcf::ThreadCalcBlock::~ThreadCalcBlock ( )

virtual

Destructor

Member Function Documentation

const dcf::error_t& dcf::ThreadCalcBlock::getThreadStatus ( )

protected

Get thread calculation result status

int dcf::ThreadCalcBlock::id ( ) const

inline

Id of current thread.

dcf::error_t dcf::ThreadCalcBlock::releaseUnit ( )

protected

Release allocated unit and define status as "not working"

virtual void dcf::ThreadCalcBlock::run ( )

protectedvirtual

Main thread calculation method.

Default implementation sets Deferred type of cancelation. If developer decide to use in reimplemented run() method the functions, that are not safe for asynchronous cancelation, he should run default run() method in his reimplementaion, and then manually define (by means of setStopPoint() method) the points of code, where the cancelation can be applied.

Reimplemented from dcf::CalcBlock.

void dcf::ThreadCalcBlock::setStopPoint ( )

protected

Can be used in run() method to define the time points, 

where the thread can be forcibly canceled without negative consequences. For more information one should read about asynchronous cancellation and async-cancel-safe functions.

void dcf::ThreadCalcBlock::setThreadStatus ( dcf::error_t  st )

protected

Set thread calculation result status

virtual void dcf::ThreadCalcBlock::start ( )

virtual

Initialize thread and start calculations by executing exec() method

Reimplemented from dcf::CalcBlock.

virtual void dcf::ThreadCalcBlock::stop ( )

virtual

Send request for thread termination

Reimplemented from dcf::CalcBlock.

virtual void dcf::ThreadCalcBlock::wait ( )

virtual

Wait for thead work finishing (or thread termination)

Reimplemented from dcf::CalcBlock.
