Interface ResultList

All Superinterfaces:

com.solarmetric.util.Closeable, Collection, List, Serializable

public interface ResultList

extends List, Serializable, com.solarmetric.util.Closeable

List interface that represents a potentially lazy ResultList instantiation.

A ResultList will typically be instantiated from a factory, and will use a ResultObjectProvider for obtaining individual object data representations.

Depending on the support for scrolling inputs, the list that is returned may use lazy instantiation of the objects, and thus allow very large result sets to be obtained and manipulated.

Note that wrapping a ResultList in another Collection will always instantiate the entire set of elements contained in the ResultList. This may not always be desireable, since the list may be very large.

Method Summary

void	close() Close the list.
boolean	isClosed() Returns true if the list has been closed.
