Batch

public final class Batch extends PendingResult <R extends Result >

Handles a batch of PendingResult items. Callbacks can be added and you can block to wait for all items in the batch to complete like any other PendingResult item. A Batch can also be canceled if the results are no longer needed. In this case, the onBatchComplete callback will never be triggered.

The results can be taken either from the underlying PendingResult s or via BatchResult.take(BatchResultToken) but not both.

Fields

protected final WeakReference < GoogleApiClient > mApiClient

This reference will never be null so long as the GoogleApiClient is connected. It needs to be weak so that PendingResults don't pin disconnected GACs due to binder references to the PendingResults.

Public Methods

public final R extends Result await ()

Blocks until the task is completed. This is not allowed on the UI thread. The returned result object can have an additional failure mode of CommonStatusCodes.INTERRUPTED .

public final R extends Result await (long time, TimeUnit units)

Blocks until the task is completed or has timed out waiting for the result. This is not allowed on the UI thread. The returned result object can have an additional failure mode of either CommonStatusCodes.INTERRUPTED or CommonStatusCodes.TIMEOUT .

public void cancel ()

Requests that the batch be canceled. Cancels all underlying PendingResult s.

ResultCallback.onResult(Result) will never be called, await() will return a failed result with status CommonStatusCodes.CANCELED .

public void clearResultCallback ()

public BatchResult createFailedResult ( Status status)

Creates a result of type <R> that represents a failure with the specified Status .

public boolean isCanceled ()

Indicates whether the pending result has been canceled either due to calling GoogleApiClient.disconnect() or calling cancel() directly on the pending result or an enclosing Batch .

public final void setResultCallback ( ResultCallback <? super R extends Result > callback)

Set the callback here if you want the result to be delivered via a callback when the result is ready.

public final void setResultCallback ( ResultCallback <? super R extends Result > callback, long time, TimeUnit units)

Set the callback here if you want the result to be delivered via a callback when the result is ready or has timed out waiting for the result. The returned result object can have an additional failure mode of CommonStatusCodes.TIMEOUT .
