public function InitializeLifetimeService () : Object

Return Value

An object of type ILease used to control the lifetime policy for this instance. This is the current lifetime service object for this instance if one exists; otherwise, a new lifetime service object initialized to the value of the LifetimeServices.LeaseManagerPollTime property.

Exception typeCondition

SecurityException

For more information about lifetime services, see the LifetimeServices class.

The following code example demonstrates creating a lease.

public class MyClass : MarshalByRefObject
{
  [SecurityPermissionAttribute(SecurityAction.Demand, 
                               Flags=SecurityPermissionFlag.Infrastructure)]
  public override Object InitializeLifetimeService()
  {
    ILease lease = (ILease)base.InitializeLifetimeService();
    if (lease.CurrentState == LeaseState.Initial)
    {
         lease.InitialLeaseTime = TimeSpan.FromMinutes(1);
         lease.SponsorshipTimeout = TimeSpan.FromMinutes(2);
          lease.RenewOnCallTime = TimeSpan.FromSeconds(2);
    }
      return lease;
  }
}

public class MyClass extends MarshalByRefObject
{
    /** @attribute System.Security.Permissions.SecurityPermissionAttribute(System.Security.
        Permissions.SecurityAction.Demand, Flags=System.Security.Permissions.SecurityPermissionFlag.Infrastructure)
     */
    public Object InitializeLifetimeService()
    {
        ILease lease = (ILease)(super.InitializeLifetimeService());
        if (lease.get_CurrentState().Equals(LeaseState.Initial)) {
            lease.set_InitialLeaseTime(TimeSpan.FromMinutes(1));
            lease.set_SponsorshipTimeout(TimeSpan.FromMinutes(2));
            lease.set_RenewOnCallTime(TimeSpan.FromSeconds(2));
        }
        return lease;
    } //InitializeLifetimeService
} //MyClass
