Class AvlMasterTable

java.lang.Object

org.apache.directory.server.xdbm.AbstractTable<K,V>

org.apache.directory.server.xdbm.impl.avl.AvlTable<String,org.apache.directory.api.ldap.model.entry.Entry>

org.apache.directory.server.xdbm.impl.avl.AvlMasterTable

All Implemented Interfaces:

MasterTable, Table<String,org.apache.directory.api.ldap.model.entry.Entry>

public class AvlMasterTable
extends AvlTable<String,org.apache.directory.api.ldap.model.entry.Entry>
implements MasterTable

TODO Make it so the master table does not extend table interface - not needed with this single use of delete so we should just use containment.
