Callback definition for

 ArSession_resolveCloudAnchorAsync

 ArResolveCloudAnchorFuture

typedef

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.

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

void

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

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 .

Parameters

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