Interface ConversionMap<K,V>

All Superinterfaces:

Map<K,V>

All Known Implementing Classes:

ColumnMap, XMLMap

public interface ConversionMap<K,V>
extends Map<K,V>

This is a specific type of map that allows for converting from a data type to a given type. For instance, a ColumnMap contains column names from an SQL table as its keys and the values are the entries, which are strings. A call to getDate(Object) would convert the string to a date object. This encapsulates all the work involved in converting between objects. This is part of the data abstraction layer for all stores.
