Method Detail

set

public void set(T result)

Sets the result. If another thread has called get(long), they will immediately receive the value. Must only be called once.

get

@Nullable
public T get(long timeoutMS)

Wait up to the timeout time for another Thread to set a value on this future. If a value has already been set, this method will return immediately. NB: For simplicity, we catch and wrap InterruptedException. Do NOT use this class if you are in the 1% of cases where you actually want to handle that.
