org.gvsig.tools.util.impl.DefaultServiceLoader

All Implemented Interfaces:

ServiceLoader

public class DefaultServiceLoader
extends java.lang.Object
implements ServiceLoader

Implementation which uses reflection to try to use first the standard JDK utilities to load service implementation classes, which are available since JDK 1.6. If it fails or the JDK used is < 1.6, the old mechanism based on the usage of internal sun classes is used.

To register your implementations classes eLfor a service, use the mechanism explained in the Java JAR file specification for the JDK version you are using:

• JDK 1.4
• JDK 1.5
• JDK 1.6
