Examples of org.hsqldb.lib.HashMappedList

org.hsqldb.lib.HashMappedList
Implementation of an Map which maintains the user-defined order of the keys. Key/value pairs can be accessed by index or by key. Iterators return the keys or values in the index order. This class does not store null keys. @author Fred Toussi (fredt@users dot sourceforge.net) @version 1.9.0 @since 1.7.2
