Example 12 with Role

use of org.apache.geode.distributed.Role in project geode by apache.

the class DistributedRegion method isNoDistributionOk.

/**
   * Called when we do a distributed operation and don't have anyone to distributed it too. Since
   * this is only called when no distribution was done (i.e. no recipients) we do not check
   * isMissingRequiredRoles because it might not longer be true due to race conditions
   * 
   * @return false if this region has at least one required role and queuing is configured. Returns
   *         true if sending to no one is ok.
   * @throws RoleException if a required role is missing and the LossAction is either NO_ACCESS or
   *         LIMITED_ACCESS.
   * @since GemFire 5.0
