Processor that blocks all frames except system frames
NullFilter
is a filtering processor that blocks all frames from passing through, with the exception of system frames and end frames which are required for proper pipeline operation.
The NullFilter
constructor accepts no specific parameters beyond those inherited from FrameProcessor
.
When a frame passes through the processor:
SystemFrame
or EndFrame
, it is passed throughThis filter effectively acts as a barrier that allows only the essential system frames required for pipeline initialization, shutdown, and management.
NullFilter
is useful in several scenarios:
