Class aRTquerier

Description

Class that manipulates the result of a database query. It returns the objects one by one, and can slide a temporal aRTtheme.

Objects from the Class

Objects can be created by calling openQuerier() from aRTlayer or from aRTtheme.

Extends

Class aRTcomponent, directly.

Methods

getData:

Returns the next element of the query result in the actual slide.

nextFrame:

Loads the next frame, if there is a temporal sliding. A temporal query needs to load one slide before using getData for getting its elements. Non-temporal queries can't use this function. Note that you can do a non-temporal query in a temporal layer.
