Detailed Description

A class responsible for loading spatio-temporal elements from a TerraLib database.

This class implements a mechanism that is responsible for loading spatio-temporal elements from a TerraLib database, following a specific strategy (Strategy 2). Each spatio-temporal elements is represented through a TeSTInstance class. This class is internally used by the factory of queriers. It should NOT be used by anyone. This Strategy 2 works with simple chronon, without geometry, theme with collection table and existence operator in the DBMS.
