Examples of com.google.api.client.googleapis.batch.BatchRequest

com.google.api.client.googleapis.batch.BatchRequest

An instance of this class represents a single batch of requests.

Sample use:

 BatchRequest batch = new BatchRequest(transport, httpRequestInitializer); batch.queue(volumesList, Volumes.class, GoogleJsonErrorContainer.class, new BatchCallback<Volumes, GoogleJsonErrorContainer>() { public void onSuccess(Volumes volumes, GoogleHeaders responseHeaders) { log("Success"); printVolumes(volumes.getItems()); } public void onFailure(GoogleJsonErrorContainer e, GoogleHeaders responseHeaders) { log(e.getError().getMessage()); } }); batch.queue(volumesList, Volumes.class, GoogleJsonErrorContainer.class, new BatchCallback<Volumes, GoogleJsonErrorContainer>() { public void onSuccess(Volumes volumes, GoogleHeaders responseHeaders) { log("Success"); printVolumes(volumes.getItems()); } public void onFailure(GoogleJsonErrorContainer e, GoogleHeaders responseHeaders) { log(e.getError().getMessage()); } }); batch.execute();

The content of each individual response is stored in memory. There is thus a potential of encountering an {@link OutOfMemoryError} for very large responses.

Redirects are currently not followed in {@link BatchRequest}.

Implementation is not thread-safe.
