Detailed Documentation

An execution stream.

Construction

stream()

Constructs an empty stream.

An empty stream cannot be used in any operations.

stream(const engine& aengine, flags aflags = flags::default_flags)

Constructs a stream for the specified engine and with behavior controlled by the specified flags.

Parameters:

aengine	Engine to create the stream on.
aflags	Flags controlling stream behavior.

Methods

engine get_engine() const

Returns the associated engine.

stream& wait()

Waits for all primitives executing in the stream to finish.

Returns:

The stream itself.

handle()

Constructs an empty handle object.

WARNING:

Uninitialized object cannot be used in most library calls and is equivalent to a null pointer. Any attempt to use its methods, or passing it to the other library function, will cause an exception to be thrown.

handle(const handle<T, traits>&)

Copy constructor.

handle(handle<T, traits>&&)

Move constructor.

handle(T t, bool weak = false)

Constructs a handle wrapper object from a C API handle.

Parameters:

t	The C API handle to wrap.
weak	A flag specifying whether to construct a weak wrapper; defaults to `false`.
