java.lang.Object
- rx.internal.operators.OperatorToMap<T,K,V>

Type Parameters:

T - the value type of the input

K - the map-key type

V - the map-value type

All Implemented Interfaces:

Func1<Subscriber<? super java.util.Map<K,V>>,Subscriber<? super T>>, Function, Observable.Operator<java.util.Map<K,V>,T>
```
public final class OperatorToMap<T,K,V>
extends java.lang.Object
implements Observable.Operator<java.util.Map<K,V>,T>
```
