Q - The query

R - The query result

All Known Implementing Classes:

LdapDataSourceFactory, SqlDataSourceFactory

public interface DataSourceFactory<Q extends Query,R extends QueryResult>

The DataSource Factory is responsible for building DataSource and Query objects. It handles one or several DataSource/Query types.

R	execute(Q query, Map<String,String> parameterValues)	Execute the query with the specified parameter values.
R	execute(Q query, Map<String,String> parameterValues, int offset, int limit)	Execute the query with the specified parameter values.
Collection<DataSourceClientInteraction.DataSourceType>	getHandledTypes()	Get the types that the factory can build.
Collection<String>	getQueryConfigurationParameters(String type)	The configuration parameters needed to build a Query of the specified type.
