Interface SQLNameAnalyser
public interface SQLNameAnalyser
SQLNameAnalyser lets users map names of tables/columns
by themselves at runtime. Usually, JReport maps mapping names of
tables/columns to sql Names itself when trying to create a SQL
statement. Those sql names are fetched from catalog. But if users
provide an implementation of this interface, JReport will call
it to create SQL statement at runtime, giving more flexibility
to let users run one report on different data sources.
Note: in order to use Class.forName() to create a new Class for the
implementation of SQLNameAnalyser, any implemented class must
have a default constructor.
