  - await
```
public Awaitable await()
                throws java.lang.InterruptedException
```
    Awaitable.await()
    
    Throws:
    
    java.lang.InterruptedException - if interrupted
  - awaitUntil
```
public boolean awaitUntil(long nanoTimeDeadline)
                   throws java.lang.InterruptedException
```
    Awaitable.awaitUntil(long)
    
    Returns:
    
    true if we were signalled, false if the deadline elapsed
    
    Throws:
    
    java.lang.InterruptedException - if interrupted
  - signal
```
protected void signal()
```
    Signal any waiting threads; isSignalled() must return true before this method is invoked.
  - isSignalled
```
protected abstract boolean isSignalled()
```
    Return true once signalled. Unidirectional; once true, must never again be false.
