public ScheduledFuture schedule(Callable callable, long delay, TimeUnit unit) {
    DelegatingScheduledFuture future = new DelegatingScheduledFuture(callable);

}

Example 34 with ScheduledFuture

use of java.util.concurrent.ScheduledFuture in project geode by apache.

the class StorageCommand method scheduleExpiration.

/**
   * Schedules the entry to expire based on the following: the expiration time sent may either be
   * Unix time (number of seconds since January 1, 1970, as a 32-bit value), or a number of seconds
   * starting from current time. In the latter case, this number of seconds may not exceed
   * 60*60*24*30 (number of seconds in 30 days); if the number sent by a client is larger than that,
   * the server will consider it to be real Unix time value rather than an offset from current time.
   * 
   * @param key
   * @param p_expTime
   * @param cache

Example 35 with ScheduledFuture

use of java.util.concurrent.ScheduledFuture in project geode by apache.

the class StorageCommand method rescheduleExpiration.
