Class 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).
