Class CdbReaderFactory

java.lang.Object
org.eso.ias.cdb.CdbReaderFactory
public class CdbReaderFactory extends Object
The factory to get the CdbReader implementation to use. This class checks the parameters of the command line, the java properties and the environment variable to build and return the CdbReader to use for reading the CDB. It offers a common strategy to be used consistently by all the IAS tools. The strategy is as follows: - if -cdbClass java.class param is present in the command line then the passed class is dynamically loaded and built (empty constructor); the configuration parameters eventually expected by such class will be passed by means of java properties (-D...) - else if jCdb file.path param is present in the command line then the JSON/YAML CDB implementation will be returned with the passed file path (the type JSON/YAML is retrieved from the content of the folder itself) - else the RDB implementation is returned (note that the parameters to connect to the RDB are passed in the hibernate configuration file) RDB implementation is the fallback if none of the other possibilities succeeds.
