Class DataSource

java.lang.Object
com.vividsolutions.jump.io.datasource.DataSource
Direct Known Subclasses:
DataStoreQueryDataSource, InstallDummyReaderPlugIn.DummyDataSource, ReaderWriterFileDataSource
public abstract class DataSource extends Object
A file, database, web service, or other source of data. To be savable to a project file, a DataSource must not be an anonymous class (because the class name is recorded in the project file) and it must have a parameterless constructor (so it can be reconstructed by simply being instantiated and having #setProperties called).
