Condition (apache-cassandra API)

All Superinterfaces:

Awaitable

All Known Subinterfaces:

ConditionAsConsumer<T>, WaitQueue.Signal

All Known Implementing Classes:

Condition.Async, Condition.Sync, ConditionAsConsumer.Async, WaitQueue.Standard.AbstractSignal
```
public interface Condition
extends Awaitable
```
Simpler API than java.util.concurrent.Condition; would be nice to extend it, but also nice to share API with Future, for which Netty's API is incompatible with java.util.concurrent.Condition Awaitable for explicit external signals.

- Method Detail
  - isSignalled
```
boolean isSignalled()
```
    Returns true once signalled. Unidirectional; once true, will never again be false.
  - signal
```
void signal()
```
    Signal the condition as met, and wake all waiting threads.
  - signalAll
```
default void signalAll()
```
    Signal the condition as met, and wake all waiting threads.
  - newOneTimeCondition
```
static Condition newOneTimeCondition()
```
    Factory method used to capture and redirect instantiations for simulation
