OutputHandler
Base class for handling MediaPipe task graph outputs.
Nested Classes
| interface | OutputHandler.OutputPacketConverter<OutputT extends TaskResult, InputT> | Interface for converting MediaPipe graph output ERROR(/Packet)s to task result object and task
input object. |
|
| interface | OutputHandler.ProgressListener<OutputT> | Interface for the customizable MediaPipe task result listener that receives partial task
updates until it is invoked with `done` set to true. |
|
| interface | OutputHandler.PureResultListener<OutputT extends TaskResult> | Interface for the customizable MediaPipe task result listener that can only retrieve task result objects. | |
| interface | OutputHandler.ResultListener<OutputT extends TaskResult, InputT> | Interface for the customizable MediaPipe task result listener that can retrieve both task result objects and the corresponding input data. | |
| interface | OutputHandler.ValueListener<OutputT> | Interface for the customizable MediaPipe task result listener that only receives a task's output value. | |
