Constructor & Destructor Documentation

Realization() [1/5]

Halide::Realization::Realization ( const Buffer< void > & e )

explicit

Construct a Realization that acts as a reference to a single existing Buffer.

The element type of the Buffer may not be const.

Realization() [2/5]

Halide::Realization::Realization ( Buffer< void > && e )

explicit

Realization() [3/5]

Halide::Realization::Realization ( const std::vector< Buffer< void > > & e )

explicit

Construct a Realization that refers to the buffers in an existing vector of Buffer<>.

The element type of the Buffer(s) may not be const

Realization() [4/5]

Halide::Realization::Realization ( std::vector< Buffer< void > > && e )

explicit

Realization() [5/5]

Halide::Realization::Realization ( std::initializer_list< Buffer< void > > e )

Single-element realizations are implicitly castable to Buffers.

device_sync()

int Halide::Realization::device_sync

(

void *

ctx = nullptr

)

Call device_sync() for all Buffers in the Realization.

If one of the calls returns an error, subsequent Buffers won't have device_sync called; thus callers should consider a nonzero return code to mean that potentially all of the Buffers are in an indeterminate state of sync. Calling this explicitly should rarely be necessary, except for profiling.
