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,

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:
TDomainPartitionerA class that inherits from ThreadedDomainPartitioner.
TAssociateThe 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.
