Detailed Description

Standard barrier class implementation for synchronizing the execution of threads.

A barrier class is used to synchronize threaded execution by allowing threads to block until each has reached a desired state. As each thread enters the barrier it blocks. When all threads have entered the barrier, all released and continue to execute.

A thread enters the barrier by calling Wait() on the barrier class. To set up a barrier class, call Initialize(n) where n is the number of waiting threads that will trigger a release of the barrier.

Member Function Documentation

virtual::itk::LightObject::Pointer itk::Barrier::CreateAnother ( void ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual const char* itk::Barrier::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::LightObject.

void itk::Barrier::Initialize ( unsigned int )

Creates a new system variable used to implement the barrier. The argument to this method is the number of threads that must Wait() on the barrier before it is cleared.

static Pointer itk::Barrier::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::LightObject.

void itk::Barrier::Wait ( )

A thread calling this method waits until m_NumberOfThreads have called Wait() on the barrier. When the final expected thread calls Wait(), all threads are released.
