Method Detail

getPermissions

protected PermissionCollection getPermissions(CodeSource cs)

Description copied from class: URLClassLoader

Returns the permissions for the given codesource object. The implementation of this method first calls super.getPermissions and then adds permissions based on the URL of the codesource.

If the protocol is "file" and the path specifies a file, then permission to read that file is granted. If protocol is "file" and the path is a directory, permission is granted to read all files and (recursively) all files and subdirectories contained in that directory.

If the protocol is not "file", then to connect to and accept connections from the URL's host is granted.

Overrides:

getPermissions in class URLClassLoader

Parameters:

cs - the codesource

Returns:

the permissions granted to the codesource

loadClass

public Class loadClass(String classname,
                       boolean resolve)
                throws ClassNotFoundException

Description copied from class: ClassLoader

Loads the class with the specified name. The default implementation of this method searches for classes in the following order:

1. Invoke ClassLoader.findLoadedClass(String) to check if the class has already been loaded.

2. Invoke the loadClass method on the parent class loader. If the parent is null the class loader built-in to the virtual machine is used, instead.

3. Invoke the ClassLoader.findClass(String) method to find the class.

If the class was found using the above steps, and the resolve flag is true, this method will then invoke the ClassLoader.resolveClass(Class) method on the resulting Class object.

Subclasses of ClassLoader are encouraged to override ClassLoader.findClass(String), rather than this method.

Overrides:

loadClass in class ClassLoader

Parameters:

classname - The name of the class

resolve - If true then resolve the class

Returns:

The resulting Class object

Throws:

ClassNotFoundException - If the class could not be found
