public interface FailureCallback<T>
Simple interface that allows asynchronous code to perform a parameterized callback in a similar way to GWT's callback interface. This is the base interface for com.codename1.util.Callback where the logic is broken down to single method interfaces so Java 8 lambdas can be used.
