Class MapDataProvider

java.lang.Object

lumis.service.wsrp.consumer.doui.MapDataProvider

All Implemented Interfaces:

IDataProvider<TabularSource<?>>

Direct Known Subclasses:

PropertiesDataProvider

public abstract class MapDataProvider
extends java.lang.Object
implements IDataProvider<TabularSource<?>>

Abstract class that implements IDataProvider and provides a general behavior to Key/Value Data Providers. Each row in the TabularData contain only two keys: 'key' and 'value'. The subclasses of MapDataProvider must only provide the implementation for the method obtainMapData - that has to return a Map. The MapDataProvider class has the ability to construct the TabularData from the Map.
