 org.apache.beehive.netui.util.internal.DiscoveryUtils
| DiscoveryUtils | | public class DiscoveryUtils (Code) | | Utility methods for discovering implementor classes on the classpath. An implementor class is declared in the
standard way, in a file within META-INF/services where the file name is the class name of the desired interface, and
the file contains the class name of the implementation. For example, to declare test.MyServiceImpl as a
test.MyService implementation, the file META-INF/services/test.MyService is put on classpath (e.g., in a JAR),
with contents "test.MyServiceImpl".

| Method Summary | |
| public static ClassLoader | getClassLoader()
Get the ClassLoader from which implementor classes will be discovered and loaded. | | public static Class[] | getImplementorClasses(Class interfaceType)
Get all implementor classes (on the context classpath) that implement a given interface.
Parameters:
interfaceType - the Class that represents the interface. | | public static Class | loadImplementorClass(String className, Class interfaceType)

Parameters:
className - the name of the implementor class.
Parameters:
interfaceType - the interface that the given class should implement. | | public static Object | newImplementorInstance(String className, Class interfaceType)
|
| getClassLoader | | public static ClassLoader getClassLoader()(Code) | | Get the ClassLoader from which implementor classes will be discovered and loaded.
|
| getImplementorClasses | | public static Class[] getImplementorClasses(Class interfaceType)(Code) | | Get all implementor classes (on the context classpath) that implement a given interface.
Parameters:
interfaceType - the Class that represents the interface. an array of Classes that are implementations of interfaceType. |
| loadImplementorClass | | public static Class loadImplementorClass(String className, Class interfaceType)(Code) | | Load an implementor class from the context classloader.
Parameters:
className - the name of the implementor class.
Parameters:
interfaceType - the interface that the given class should implement. the implementor Class, or null if an error occurred (the error will be logged). |
