Example 4 with WatchmanQuery

use of com.facebook.buck.io.WatchmanQuery in project buck by facebook.

the class WatchmanWatcher method postEvents.

/**
   * Query Watchman for file change events. If too many events are pending or an error occurs
   * an overflow event is posted to the EventBus signalling that events may have been lost
   * (and so typically caches must be cleared to avoid inconsistency). Interruptions and
   * IOExceptions are propagated to callers, but typically if overflow events are handled
   * conservatively by subscribers then no other remedial action is required.
   *
   * Any diagnostics posted by Watchman are added to watchmanDiagnosticCache.
