Class GreaterEqCursor<V,ID>

java.lang.Object
  org.apache.directory.server.xdbm.AbstractIndexCursor<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID>
      org.apache.directory.server.xdbm.search.impl.GreaterEqCursor<V,ID>

All Implemented Interfaces:

java.lang.Iterable<IndexEntry<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID>>, IndexCursor<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID>, org.apache.directory.shared.ldap.cursor.Cursor<IndexEntry<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID>>

public class GreaterEqCursor<V,ID>
extends AbstractIndexCursor<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID>

A Cursor over entry candidates matching a GreaterEq assertion filter. This Cursor operates in two modes. The first is when an index exists for the attribute the assertion is built on. The second is when the user index for the assertion attribute does not exist. Different Cursors are used in each of these cases where the other remains null.
