Method Details

isBlocked

public com.google.common.util.concurrent.ListenableFuture<Void> isBlocked()

Description copied from interface: DirectExchangeBuffer

This method may be called by multiple independent client concurrently. Implementations must ensure the cancellation of a future by one of the clients doesn't cancel futures obtained by other clients.
