org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPCacheManager
public class LateralTCPCacheManager
Creates lateral caches. Lateral caches are primarily used for removing non laterally configured caches. Non laterally configured cache regions should still be able to participate in removal. But if there is a non laterally configured cache hub, then lateral removals may be necessary. For flat webserver production environments, without a strong machine at the app server level, distribution and search may need to occur at the lateral cache level. This is currently not implemented in the lateral cache.
TODO: - need freeCache, release, getStats - need to find an interface acceptable for all - cache managers or a manager within a type

void |
addLateralCacheListener(String cacheName,

Adds the lateral cache listener to the underlying cache-watch service. |

fixService()
The restore calls this on the manger if a cache if found to be in error. |

getCache(String cacheName)
Called to access a precreated region or construct one with defaults. |

Returns an instance of the LateralCacheManager. |
Map |
getInstances()
This is a temporary solution that allows the monitor to get the instances of a manager. |

public AuxiliaryCache getCache(String cacheName)
After getting the manager instance for a server, the factory gets a cache for the region name it is constructing.
There should be one manager per server and one cache per region per manager.
