## Detailed Description

A Realization is a vector of references to existing Buffer objects.

A pipeline with multiple outputs realize to a Realization.

## 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.

Referenced by Realization().

## 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 | ) |

## Member Function Documentation

## size()

size_t Halide::Realization::size | ( |  | ) | const

The number of images in the Realization.

Examples
  tutorial/lesson_13_tuples.cpp.

## operator[]() [1/2]

const Buffer< void > & Halide::Realization::operator[] | ( | size_t | x | ) | const

Get a const reference to one of the images.

## operator[]() [2/2]

Buffer< void > & Halide::Realization::operator[] | ( | size_t | x | ) |

Get a reference to one of the images.

## operator Buffer< T, Dims >()

template<typename T, int Dims>

Halide::Realization::operator Buffer< T, Dims > | ( |  | ) | const

inline

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.
