Detailed Documentation

Methods

virtual TensorPtr map(TensorPtr src, 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, 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.

TensorPtr map(TensorPtr src, AccessMode mode = AccessMode::ReadWrite)

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

FramePtr map(FramePtr src, AccessMode mode = AccessMode::ReadWrite)

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
