Detailed Description

template<class TDomainPartitioner, class TAssociate>
class itk::DomainThreader< TDomainPartitioner, TAssociate >

Multi-threaded processing on a domain by processing sub-domains per thread.

This class uses a ThreadedDomainPartitioner as a helper to split the domain into subdomains. Each subdomain is then processed in the ThreadedExecution method.

The data on which to perform the processing is assumed to be members of an associating class. Therefore, to perform a threaded operation in a class, the associating class usually will declare derived versions of this class as a friend class.

To use this class, at a minimum,

Inherit from it.
Implement ThreadedExecution.
Create a member instance.
Run with m_DomainThreader->Execute( this, domain );

If a 'threaded method' is desired to perform some data processing in a class, a derived version of this class can be defined to perform the threaded operation. Since a threaded operation is relatively complex compared to a simple serial operation, a class instead of a simple method is required. Inside this class, the method to partition the data is handled, the logic for determining the number of threads is determined, and operations surrounding the threading are encapsulated into the class with the DetermineNumberOfThreadsToUse, BeforeThreadedExecution, ThreadedExecution, and AfterThreadedExecution virtual methods.

Template Parameters:

TDomainPartitioner	A class that inherits from ThreadedDomainPartitioner.
TAssociate	The asssociated class that uses a derived version of this class as a "threaded method". The associated class usually declares derived version of this class as nested classes so there is easy access to its protected and private members in ThreadedExecution.

void itk::DomainThreader< TDomainPartitioner, TAssociate >::SetMaximumNumberOfThreads ( const ThreadIdType threads )

Convenience methods to set/get the maximum number of threads to use.

Warning:: When setting the maximum number of threads, it will be clamped by itk::MultiThreader::GetGlobalMaximumNumberOfThreads() and ITK_MAX_THREADS.

	)

protectedpure virtual

Do the threaded operation, somewhat like ThreadedGenerateData in an ImageSource.

Parameters:

subdomain	The subdomain to operate on.
threadId	The identifier for the current thread. Data to perform the operation on can be accessed by dereferencing this->m_Associate, which has direct access to private and protected members the enclosing class.

Implemented in itk::ImageToImageMetricv4GetValueAndDerivativeThreader< ThreadedIndexedContainerPartitioner, TImageToImageMetricv4 >.

static ITK_THREAD_RETURN_TYPE itk::DomainThreader< TDomainPartitioner, TAssociate >::ThreaderCallback ( void * arg )

staticprotected

Static function used as a "callback" by the MultiThreader. The threading library will call this routine for each thread, which will delegate the control to the ThreadFunctor.

Store the actual number of threads used, which may be less than the number allocated by the threader if the object does not split well into that number. This value is determined at the beginning of Execute().
