Public Types | |
| parallel = current_version | filter_is_out_of_order | |
| processes multiple items in parallel and in no particular order | |
| serial_in_order = current_version | filter_is_serial | |
| processes items one at a time; all such filters process items in the same order | |
| serial_out_of_order = current_version | filter_is_serial | filter_is_out_of_order | |
| processes items one at a time and in no particular order | |
| serial = serial_in_order | |

Public Member Functions | |
| bool | is_serial () const |
| True if filter is serial. | |
| bool | is_ordered () const |
| True if filter must receive stream in order. | |
| bool | is_bound () const |
| True if filter is thread-bound. | |
| virtual void * | operator() (void *item)=0 |
| Operate on an item from the input stream, and return item for output stream. | |
| virtual __TBB_EXPORTED_METHOD | ~filter () |
| Destroy filter. | |
| virtual void | finalize (void *) |
| Destroys item if pipeline was cancelled. | |

|
| virtual __TBB_EXPORTED_METHOD tbb::filter::~filter | ( | ) | [virtual] |
Destroy filter.
If the filter was added to a pipeline, the pipeline must be destroyed first.
| virtual void tbb::filter::finalize | ( | void * | ) | [inline, virtual] |
Destroys item if pipeline was cancelled.
Required to prevent memory leaks. Note it can be called concurrently even for serial filters.
| virtual void* tbb::filter::operator() | ( | void * | item | ) | [pure virtual] |
Operate on an item from the input stream, and return item for output stream.
Returns NULL if filter is a sink.
