Methods Summary
public abstract java.lang.String	getClassAnnotation(java.lang.Class cl) Provides the implementation for {@link RMIClassLoader#getClassAnnotation(Class)}. Returns the annotation string (representing a location for the class definition) that RMI will use to annotate the class descriptor when marshalling objects of the given class. param cl the class to obtain the annotation for return a string to be used to annotate the given class when it gets marshalled, or null throws NullPointerException if cl is null
public abstract java.lang.ClassLoader	getClassLoader(java.lang.String codebase) Provides the implementation for {@link RMIClassLoader#getClassLoader(String)}. Returns a class loader that loads classes from the given codebase URL path. If there is a security manger, its checkPermission method will be invoked with a RuntimePermission("getClassLoader") permission; this could result in a SecurityException. The implementation of this method may also perform further security checks to verify that the calling context has permission to connect to all of the URLs in the codebase URL path. param codebase the list of URLs (space-separated) from which the returned class loader will load classes from, or null return a class loader that loads classes from the given codebase URL path throws MalformedURLException if codebase is non-null and contains an invalid URL, or if codebase is null and a provider-specific URL used to identify the class loader is invalid throws SecurityException if there is a security manager and the invocation of its checkPermission method fails, or if the caller does not have permission to connect to all of the URLs in the codebase URL path
public abstract java.lang.Class	loadClass(java.lang.String codebase, java.lang.String name, java.lang.ClassLoader defaultLoader) Provides the implementation for {@link RMIClassLoader#loadClass(URL,String)}, {@link RMIClassLoader#loadClass(String,String)}, and {@link RMIClassLoader#loadClass(String,String,ClassLoader)}. Loads a class from a codebase URL path, optionally using the supplied loader. Typically, a provider implementation will attempt to resolve the named class using the given defaultLoader, if specified, before attempting to resolve the class from the codebase URL path. An implementation of this method must either return a class with the given name or throw an exception. param codebase the list of URLs (separated by spaces) to load the class from, or null param name the name of the class to load param defaultLoader additional contextual class loader to use, or null return the Class object representing the loaded class throws MalformedURLException if codebase is non-null and contains an invalid URL, or if codebase is null and a provider-specific URL used to load classes is invalid throws ClassNotFoundException if a definition for the class could not be found at the specified location
public abstract java.lang.Class	loadProxyClass(java.lang.String codebase, java.lang.String[] interfaces, java.lang.ClassLoader defaultLoader) Provides the implementation for {@link RMIClassLoader#loadProxyClass(String,String[],ClassLoader)}. Loads a dynamic proxy class (see {@link java.lang.reflect.Proxy} that implements a set of interfaces with the given names from a codebase URL path, optionally using the supplied loader. An implementation of this method must either return a proxy class that implements the named interfaces or throw an exception. param codebase the list of URLs (space-separated) to load classes from, or null param interfaces the names of the interfaces for the proxy class to implement return a dynamic proxy class that implements the named interfaces param defaultLoader additional contextual class loader to use, or null throws MalformedURLException if codebase is non-null and contains an invalid URL, or if codebase is null and a provider-specific URL used to load classes is invalid throws ClassNotFoundException if a definition for one of the named interfaces could not be found at the specified location, or if creation of the dynamic proxy class failed (such as if {@link java.lang.reflect.Proxy#getProxyClass(ClassLoader,Class[])} would throw an IllegalArgumentException for the given interface list)
