Examples with DaemonExpirationListener org.gradle.launcher.daemon.server.expiry.DaemonExpirationListener used on opensource projects

Example 1 with DaemonExpirationListener

use of org.gradle.launcher.daemon.server.expiry.DaemonExpirationListener in project gradle by gradle.

the class DefaultDaemonScanInfo method notifyOnUnhealthy.

@Override
public void notifyOnUnhealthy(final Action<? super String> listener) {
    /*
            The semantics of this method are that the given action should be notified if the
            Daemon is going to be terminated at the end of this build.
            It is not a generic outlet for “expiry events”.

            Ideally, the value given would describe the problem and not be phrased in terms of why we are shutting down,
            but this is a practical compromise born out of piggy backing on the expiration listener mechanism to implement it.
