isSignalled

public boolean isSignalled()

Description copied from class: Awaitable.AsyncAwaitable

Return true once signalled. Unidirectional; once true, must never again be false.

Specified by:

isSignalled in interface Condition

Specified by:

isSignalled in class Awaitable.AsyncAwaitable

signal

public void signal()

Description copied from class: Awaitable.AsyncAwaitable

Signal any waiting threads; Awaitable.AsyncAwaitable.isSignalled() must return true before this method is invoked.

Specified by:

signal in interface Condition

Overrides:
