Constructor Detail

AndCursor

public AndCursor(IndexCursor<V,org.apache.directory.shared.ldap.entry.ServerEntry,ID> wrapped,
         List<Evaluator<? extends org.apache.directory.shared.ldap.filter.ExprNode,org.apache.directory.shared.ldap.entry.ServerEntry,ID>> evaluators)

Method Detail

available

public boolean available()

beforeValue

public void beforeValue(ID id,
               V value)

Description copied from interface: IndexCursor

An alternative to calling before(IndexEntry) which often may require wrapping an id and value in a newly created IndexEntry object that may be an unnecessary object creation. Some implementations may not support this operation and may throw an UnsupportedOperationEception.

Parameters:

id - the id for the entry

value - the value to advance just before

afterValue

public void afterValue(ID id,
              V value)

Description copied from interface: IndexCursor

An alternative to calling after(IndexEntry) which often may require wrapping an id and value in a newly created IndexEntry object that may be an unnecessary object creation. Some implementations may not support this operation and may throw an UnsupportedOperationEception.

Parameters:

id - the id for the entry

value - the value to advance just after the last value
