Member Function Documentation

finalize()

template<typename T , typename U , typename Body >

void tbb::interface6::internal::concrete_filter< T, U, Body >::finalize ( void *  )

inlineprivatevirtual

Destroys item if pipeline was cancelled.

Required to prevent memory leaks. Note it can be called concurrently even for serial filters.

Reimplemented from tbb::filter.

Definition at line 443 of file pipeline.h.

                                               {
        t_pointer temp_input = t_helper::cast_from_void_ptr(input);
        t_helper::destroy_token(temp_input);
    }

operator()()

template<typename T , typename U , typename Body >

void* tbb::interface6::internal::concrete_filter< T, U, Body >::operator() ( void *  item )

inlineprivatevirtual

Operate on an item from the input stream, and return item for output stream.

Returns NULL if filter is a sink.

Implements tbb::filter.

Definition at line 436 of file pipeline.h.

                                                 {
        t_pointer temp_input = t_helper::cast_from_void_ptr(input);
