Constructor & Destructor Documentation

ola::thread::Thread::Thread ( const Options &  options = Options() )

explicit

Create a new thread with the specified thread options.

Parameters

options

the thread's options

Member Function Documentation

bool ola::thread::Thread::FastStart ( )

virtual

Start the thread and return immediately.

Returns

true if the thread started, false otherwise.

Don't use this unless you know what you're doing, since it introduces a race condition with Join().

ThreadId ola::thread::Thread::Id ( ) const

inline

Return the thread id.

Returns

the thread id.

bool ola::thread::Thread::IsRunning

(

)

Check if the thread is running.

Returns

true if the thread was running at some point in the past.

This is best-effort only, since the thread may stop after IsRunning() returns.

bool ola::thread::Thread::Join ( void *  ptr = NULL )

virtual

Join this thread.

Parameters

[out]

ptr

The value returned from the thread.

Returns

false if the thread wasn't running or didn't stop, true otherwise.

Reimplemented in ola::FilePreferenceSaverThread, and ola::plugin::usbpro::WidgetDetectorThread.

std::string ola::thread::Thread::Name ( ) const

inline

Return the thread name.

Returns

the thread name.

This may differ from the name assigned with pthread_setname, since the latter has a limit of 16 characters.

virtual void* ola::thread::Thread::Run ( )

protectedpure virtual

The entry point for the new thread.

Returns

A value returned to Join().

Sub classes must implement this.

Implemented in ola::FilePreferenceSaverThread, ola::plugin::spi::SoftwareBackend, ola::http::HTTPServer, ola::plugin::spi::HardwareBackend, ola::plugin::usbpro::WidgetDetectorThread, ola::thread::ConsumerThread, ola::thread::SignalThread, ola::thread::CallbackThread, ola::plugin::ftdidmx::FtdiDmxThread, ola::plugin::opendmx::OpenDmxThread, ola::plugin::karate::KarateThread, and ola::plugin::uartdmx::UartDmxThread.

static ThreadId ola::thread::Thread::Self ( )

inlinestatic

Returns the current thread's id.

Returns

the current thread's id.

bool ola::thread::Thread::Start ( )

virtual

Start the thread and wait for the thread to be running.

Returns

true if the thread started, false otherwise.

This will block until the thread is running. Use FastStart() if you don't want to block.
