Detailed Documentation

Methods

virtual TensorPtr map(TensorPtr src, dlstreamer::AccessMode mode)

Map tensor into another context. The function returns mapped tensor, so that the parent() on output tensor returns original tensor and context() on output tensor returns input_context().

Parameters:

src	Tensor to map
mode	Access mode - read or write or read+write

virtual FramePtr map(FramePtr src, dlstreamer::AccessMode mode)

Map frame into another context. The function returns mapped frame, so that the parent() on output frame returns original frame and context() on output frame returns input_context().

Parameters:

src	Frame to map
mode	Access mode - read or write or read+write

virtual ContextPtr input_context() const

Returns context specified as input context on mapper object creation.

virtual ContextPtr output_context() const

Returns context specified as output context on mapper object creation.
