A connector DataSource is an implementation of the abstract java class AbstractDataSource. When defining a DataSource the following functions require implementation: 

     public abstract String getDataSourceName(); 

     public abstract Collection<AbstractDataSet> getDataSets(); 

     public abstract JDBCMetaData getDataSourceMetaData(); 

     public abstract boolean authenticate() throws Exception; 

     public abstract void disconnect(); 

     public abstract Map<String, Object> testConnection() throws Exception 

...

The following functions can optionally be overwritten: 

     public ScheduleDefinition getScheduleDefinition(); 

     public boolean autoRun() { return true; }; 

The following functions are available as utility functions: 

     protected final byte[] loadBlob(String key); 

     protected final boolean saveBlob(String key, byte[] data); 

     protected final boolean areBlobsAvailable(); 

     public final Object getAttribute(String key); 

     public final Integer getSourceId();
