public abstract class SessionFactory extends java.lang.Object
This class is used to retrieve a Session instance tailored to the DRM and DRMAA implementation in use. The factory will use the org.ggf.drmaa.SessionFactory property to discover the DRM-specific Session implementation class.Example:
public static void main(String[] args) throws Exception { SessionFactory factory = SessionFactory.getFactory(); Session session = factory.getSession(); session.init(""); session.exit(); }

getFactory
public static SessionFactory getFactory()
Gets a SessionFactory instance appropriate for the DRM in use. This method uses the org.ggf.drmaa.SessionFactory property to find the appropriate class. It looks first in the system properties. If the property is not present, the method looks in $java.home/lib/drmaa.properties. If the property still isn't found, the method will search the classpath for a META-INF/services/org.ggf.drmaa.SessionFactory resource. If the property still has not been found, the method throws an Error.- Returns:
- a SessionFactory instance appropriate for the DRM in use
- Throws:
java.lang.Error
- if an appropriate SessionFactory implementation could not be found or instantiated
