Interface Performer<T>

All Superinterfaces:

QBCancelable

public interface Performer<T>
extends QBCancelable

An invocation of a QB API REST request that sends a request to a webserver and returns a response.

Performer may be executed synchronously with perform(), or asynchronously with performAsync(com.quickblox.core.QBEntityCallback<T>). In either case the request can be canceled at any time with QBCancelable.cancel().

 Performer performer = QBAuth.createSession();

  //asynchronous request
 performer.performAsync(new QBEntityCallback() {
      @Override
      public void onSuccess(QBSession result, Bundle params) {

      }

      @Override
      public void onError(QBResponseException responseException) {

      }
 });


  //synchronous request

 try {
      QBSession perform = performer.perform();
 } catch (QBResponseException e){

 }
