Field Detail

NO_ACCESS

public static final LossAction NO_ACCESS

The region is unavailable when required roles are missing. All operations including read and write access are denied. All read and write operations on the region will result in RegionAccessException while any required roles are absent. Basic administration of the region is allowed, including close and localDestroyRegion.

LIMITED_ACCESS

public static final LossAction LIMITED_ACCESS

Only local access to the region is allowed when required roles are missing. All distributed write operations on the region will throw RegionAccessException while any required roles are absent. Reads which result in a netSearch behave normally, while any attempt to invoke a netLoad is not allowed.

FULL_ACCESS

public static final LossAction FULL_ACCESS

Access to the region is unaffected when required roles are missing.

RECONNECT

public static final LossAction RECONNECT

Loss of required roles causes the entire cache to be closed. In addition, this process will disconnect from the DistributedSystem and then reconnect. Attempting to use any existing references to the regions or cache will throw a CacheClosedException.
