public interface DynamicDSGenerator
DynamicDSGenerators can be registered with the SmartClient Server framework via the
DataSource.addDynamicDSGenerator(DynamicDSGenerator)method. The framework will call the
getDataSourcemethod of registered
DynamicDSGeneratorswhenever it needs to obtain a DataSource, giving user code a means of generating DataSource definitions at runtime, rather than (or as well as) providing them as
.ds.xmlfiles in the filesystem.
