Examples of de.laures.cewolf.DatasetProducer.produceDataset()

de.laures.cewolf.DatasetProducer.produceDataset()

Produces a {@link org.jfree.data.general.Dataset} object. @param params additional params for the dataset production. All elementsof this HashMap are of type java.io.Serializable. This is necessary to ensure the the serialization of the dataset producer into the http session. To provide a producer with additional production parameters the <param> tag is used (see tag library documentation). It is recommended to synchronize implementations of this method to avoid concurrency problems. @return an object of type org.jfree.data.general.Dataset. @throws DatasetProduceException if an error occured during production
