Examples of org.chromium.sdk.CallbackSemaphore

org.chromium.sdk.CallbackSemaphore
Convenient implementation of {@code SyncCallback}. Client may create one, then call asynchronous command, and finally wait on blocking method {@code #tryAcquire()} or {@link #acquireDefault}.
Class uses symbolic parameter {@link RelayOk} in its methods that suggests thatuser should first call some asynchronous method, then pass it to the acquire method.
