-
-// BufferQueueInterposers introduce an extra stage between a buffer producer
-// (the source) and a buffer consumer (the sink), which communicate via the
-// IGraphicBufferProducer interface. It is designed to be as transparent as
-// possible to both endpoints, so that they can work the same whether an
-// interposer is present or not.
-//
-// When the interpose is present, the source queues buffers to the
-// IGraphicBufferProducer implemented by BufferQueueInterposer. A client of
-// the BufferQueueInterposer can acquire each buffer in turn and read or
-// modify it, releasing the buffer when finished. When the buffer is released,
-// the BufferQueueInterposer queues it to the original IGraphicBufferProducer
-// interface representing the sink.
-//
-// A BufferQueueInterposer can be used to do additional rendering to a buffer
-// before it is consumed -- essentially pipelining two producers. As an
-// example, SurfaceFlinger uses this to implement mixed GLES and HWC
-// compositing to the same buffer for virtual displays. If it used two separate
-// buffer queues, then in GLES-only or mixed GLES+HWC compositing, the HWC
-// would have to copy the GLES output buffer to the HWC output buffer, using
-// more bandwidth than having HWC do additional composition "in place" on the
-// GLES output buffer.
-//
-// The goal for this class is to be usable in a variety of situations and be
-// part of libgui. But both the interface and implementation need some
-// iteration before then, so for now it should only be used by
-// VirtualDisplaySurface, which is why it's currently in SurfaceFlinger.
-//
-// Some of the problems that still need to be solved are:
-//
-// - Refactor the interposer interface along with BufferQueue and ConsumerBase,
-// so that there is a common interface for the consumer end of a queue. The
-// existing interfaces have some problems when the implementation isn't the
-// final consumer.
-//
-// - The client of the interposer may need one or more buffers in addition to
-// those used by the source and sink. IGraphicBufferProducer will probably
-// need to change to allow the producer to specify how many buffers it needs
-// to dequeue at a time, and then the interposer can add its requirements to
-// those of the source.
-//
-// - Abandoning, disconnecting, and connecting need to pass through somehow.
-// There needs to be a way to tell the interposer client to release its
-// buffer immediately so it can be queued/released, e.g. when the source
-// calls disconnect().
-//
-// - Right now the source->BQI queue is synchronous even if the BQI->sink queue
-// is asynchronous. Need to figure out how asynchronous should behave and
-// implement that.
