Class OnErrorThrowable

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

rx.exceptions.OnErrorThrowable

All Implemented Interfaces:

Serializable

public final class OnErrorThrowable
extends RuntimeException

Represents a Throwable that an Observable might notify its subscribers of, but that then can be handled by an operator that is designed to recover from or react appropriately to such an error. You can recover more information from an OnErrorThrowable than is found in a typical Throwable, such as the item the Observable was trying to emit at the time the error was encountered.
