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()

Copy constructor.

handle()

Move constructor.

handle()

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.
