SingleSubscriber

java.lang.Object
- rx.SingleSubscriber<T>

Type Parameters:

T - the type of item the SingleSubscriber expects to observe

All Implemented Interfaces:

Subscription
```
@Beta
public abstract class SingleSubscriber<T>
extends Object
implements Subscription
```
Provides a mechanism for receiving push-based notifications.
After a SingleSubscriber calls a Single's subscribe method, the Single calls the SingleSubscriber's onSuccess(T) and onError(java.lang.Throwable) methods to provide notifications. A well-behaved Single will call a SingleSubscriber's onSuccess(T) method exactly once or the SingleSubscriber's onError(java.lang.Throwable) method exactly once.

Since:

(if this graduates from Experimental/Beta to supported, replace this parenthetical with the release number)

```
public SingleSubscriber()
```
- Method Detail
  - onSuccess
```
public abstract void onSuccess(T value)
```
    Notifies the SingleSubscriber with a single item and that the Single has finished sending push-based notifications.
    The Single will not call this method if it calls onError(java.lang.Throwable).
    
    Parameters:
    
    value - the item emitted by the Single
  - onError
```
public abstract void onError(Throwable error)
```
    Notifies the SingleSubscriber that the Single has experienced an error condition.
    If the Single calls this method, it will not thereafter call onSuccess(T).
    
    Parameters:
    
    error - the exception encountered by the Single
  - add
```
public final void add(Subscription s)
```
    Adds a Subscription to this Subscriber's list of subscriptions if this list is not marked as unsubscribed. If the list is marked as unsubscribed, add will indicate this by explicitly unsubscribing the new Subscription as well.
    
    Parameters:
    
    s - the Subscription to add
  - unsubscribe
```
public final void unsubscribe()
```
    Description copied from interface: Subscription
    
    Stops the receipt of notifications on the Subscriber that was registered when this Subscription was received.
    This allows unregistering an Subscriber before it has finished receiving all events (i.e. before onCompleted is called).
  - isUnsubscribed
```
public final boolean isUnsubscribed()
```
    Indicates whether this Subscriber has unsubscribed from its list of subscriptions.
    
    Specified by:
    
    isUnsubscribed in interface Subscription
    
    Returns:
    
    true if this Subscriber has unsubscribed from its subscriptions, false otherwise
