ArResolveCloudAnchorFuture

An asynchronous operation for resolving a Cloud Anchor launched by ArSession_resolveCloudAnchorAsync.

See the Cloud Anchors developer guide for more information.

struct ArResolveCloudAnchorFuture_
Handle to an asynchronous operation launched by ArSession_resolveCloudAnchorAsync.

Functions
ArResolveCloudAnchorFuture_acquireResultAnchor(const ArSession *session, const ArResolveCloudAnchorFuture *future, ArAnchor **out_anchor)
void
Gets the resolved Cloud Anchor.

Typedefs

ArResolveCloudAnchorCallback

void(* ArResolveCloudAnchorCallback)(void *context, ArAnchor *anchor, ArCloudAnchorState cloud_anchor_state)

Callback definition for ArSession_resolveCloudAnchorAsync.

The context argument will be the same as that passed to ArSession_resolveCloudAnchorAsync. The anchor argument will be the same as that returned by ArResolveCloudAnchorFuture_acquireResultAnchor and must be released using ArAnchor_release. The cloud_anchor_state argument will be the same as that returned by ArResolveCloudAnchorFuture_getResultCloudAnchorState.

It is a best practice to free context memory provided to ArSession_resolveCloudAnchorAsync at the end of the callback implementation.

ArResolveCloudAnchorFuture

struct ArResolveCloudAnchorFuture_ ArResolveCloudAnchorFuture

Handle to an asynchronous operation launched by ArSession_resolveCloudAnchorAsync.

Release with ArFuture_release. (reference type, long-lived).

Functions

ArResolveCloudAnchorFuture_acquireResultAnchor

void ArResolveCloudAnchorFuture_acquireResultAnchor(
  const ArSession *session,
  const ArResolveCloudAnchorFuture *future,
  ArAnchor **out_anchor
)

Gets the resolved Cloud Anchor.

If the operation isn't done yet or the operation failed, this will be NULL. The caller must release the anchor using ArAnchor_release.

Details
Parameters
session
The ARCore session.
future
The handle for the asynchronous operation.
out_anchor
The anchor.

ArResolveCloudAnchorFuture_getResultCloudAnchorState

void ArResolveCloudAnchorFuture_getResultCloudAnchorState(
  const ArSession *session,
  const ArResolveCloudAnchorFuture *future,
  ArCloudAnchorState *out_cloud_anchor_state
)

Gets the result status of the resolving operation, if the operation is done.

Details
Parameters
session
The ARCore session.
future
The handle for the asynchronous operation.
out_cloud_anchor_state
The result status.
