Interface DataCollection

All Superinterfaces:

com.highdeal.hci.XMLMarshallable

public interface DataCollection
extends com.highdeal.hci.XMLMarshallable

This Java interface represents a data collection that is processed by a running Import/Export Connector (IEC) application accordingly to your customized JavaTask; Data is mapped with keys.

For better performance, the interface provides some methods that allow the collection to be reused to limit the count of the instance creation. An instance of the DataCollection class is a set of pairs (key, value) in which the value can be a Boolean, string, date or number. A key is unique, but two keys can have the same value.

Example

The keys k1 and k2 can have the value TRUE that is a Boolean.
