All Implemented Interfaces:

GeneratedClassLoader

public class RhinoClassLoader
extends java.net.URLClassLoader
implements GeneratedClassLoader

This class loader implementation will work whether or not the documentURL is null.

Field Summary

protected java.security.CodeSource	codeSource CodeSource for classes defined by this loader
protected java.net.URL	documentURL URL for the document referencing the script.
protected java.security.AccessControlContext	rhinoAccessControlContext The AccessControlContext which can be associated with code loaded by this class loader if it was running stand-alone (i.e., not invoked by code with lesser priviledges).

Constructor Summary

RhinoClassLoader(java.net.URL documentURL, java.lang.ClassLoader parent)
Constructor.

Method Summary

java.lang.Class	defineClass(java.lang.String name, byte[] data) Define and load a Java class
java.security.AccessControlContext	getAccessControlContext() Returns the AccessControlContext which should be associated with RhinoCode.
protected java.security.PermissionCollection	getPermissions(java.security.CodeSource codesource) Returns the permissions for the given CodeSource object.
void	linkClass(java.lang.Class clazz) Links the Java class.

Field Detail

documentURL

protected java.net.URL documentURL

URL for the document referencing the script.

codeSource

protected java.security.CodeSource codeSource

CodeSource for classes defined by this loader

rhinoAccessControlContext

protected java.security.AccessControlContext rhinoAccessControlContext

The AccessControlContext which can be associated with code loaded by this class loader if it was running stand-alone (i.e., not invoked by code with lesser priviledges).

Constructor Detail

RhinoClassLoader

public RhinoClassLoader(java.net.URL documentURL,
                        java.lang.ClassLoader parent)

Constructor.

Parameters:

documentURL - the URL from which to load classes and resources

parent - the parent class loader for delegation

Method Detail

defineClass

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

Define and load a Java class

Specified by:

defineClass in interface GeneratedClassLoader

linkClass

public void linkClass(java.lang.Class clazz)

Links the Java class.

Specified by:

linkClass in interface GeneratedClassLoader

getAccessControlContext

public java.security.AccessControlContext getAccessControlContext()

Returns the AccessControlContext which should be associated with RhinoCode.

getPermissions

protected java.security.PermissionCollection getPermissions(java.security.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.

Overrides:

getPermissions in class java.net.URLClassLoader
