Class CMACallback<T>

  • Type Parameters:
    T - the type of object to be expected as a result. For methods that return a collection of resources it is required to use CMAArray as the type.

    Callback can be cancelled at any point using the cancel() method, that will prevent any future calls to onSuccess(T) and onFailure(RuntimeException).

    public abstract class CMACallback<T>
extends java.lang.Object
    Callback to be used with any of the CMAClient asynchronous methods.

    Implement the onSuccess(T) method for cases where the request was successful, the result object should be delivered as a parameter.

    It is also possible, but not mandatory to override onFailure(java.lang.RuntimeException) and provide an implementation for handling errors.
