Constructor Details

RhinoClassLoader

public RhinoClassLoader(URL documentURL,
 ClassLoader parent)

Constructor.

Parameters:

documentURL - the URL from which to load classes and resources

parent - the parent class loader for delegation

Method Details

defineClass

public Class defineClass(String name,
 byte[] data)

Define and load a Java class

Specified by:

defineClass in interface org.mozilla.javascript.GeneratedClassLoader

linkClass

public void linkClass(Class clazz)

Links the Java class.

Specified by:

linkClass in interface org.mozilla.javascript.GeneratedClassLoader

getAccessControlContext

public AccessControlContext getAccessControlContext()

Returns the AccessControlContext which should be associated with RhinoCode.

getPermissions

protected PermissionCollection getPermissions(CodeSource codesource)

Returns the permissions for the given CodeSource object. Compared to URLClassLoader, this adds a FilePermission so that files under the same root directory as the document can be read.
