LeaseOptions (Google App Engine API for Java)

com.google.appengine.api.taskqueue

Class LeaseOptions

  • java.lang.Object
    • com.google.appengine.api.taskqueue.LeaseOptions


  • public final class LeaseOptions
    extends java.lang.Object
    Contains various options for lease requests following the builder pattern. Calls to LeaseOptions methods may be chained to specify multiple options in the one LeaseOptions object.

    Notes on usage:
    The recommended way to instantiate a LeaseOptions object is to statically import LeaseOptions.Builder.* and invoke a static creation method followed by instance mutators:

     import static com.google.appengine.api.taskqueue.LeaseOptions.Builder.*;
    
     ...
     tasks = pullQueue.leaseTasks(withLeasePeriod(2, TimeUnit.HOURS).countLimit(1000));
