Methods

NameDescription
map (offset, sz) Produce a scoped memory map. The the memory will be unmapped when the object goes out of scope. The is an untyped memory holder. In order to access the memory, call view with the right type parameter.
mapRaw (offset, size) Map device memory to host visible memory.
unmapRaw ()
dispose () Dispose the underlying resource
rcLock () Returns whether the refCount >= 1. This increases the refCount by 1. rcLock should be used to keep weak reference and ensures that the resource is not disposed. The operation is atomic.
rcLockShared () Returns whether the refCount >= 1. This increases the refCount by 1. rcLock should be used to keep weak reference and ensures that the resource is not disposed. The operation is atomic.
release (disposeOnZero) Atomically decrement the reference count. If refCount reaches zero, and disposeOnZero is set, the object is locked with its own mutex, and dispose is called. In most cases, the calling code should set disposeOnZero, unless it is intended to release the object to give it away. (such as at the end of a builder function)
releaseShared (disposeOnZero) Atomically decrement the reference count. If refCount reaches zero, and disposeOnZero is set, the object is locked with its own mutex, and dispose is called. In most cases, the calling code should set disposeOnZero, unless it is intended to release the object to give it away. (such as at the end of a builder function)
retain () Atomically increment the reference count.
retainShared () Atomically increment the reference count.
