This section lists security-related classes that appear in
miscellaneous packages: permission classes, class loaders, and
security managers.
Class java.awt.AWTPermission | |
|
| |
This class represents permission to perform windowing operations,
like opening a top-level window or examining the event queue. This is
a basic permission, so it has no actions.
Class Definition
public final class java.awt.AWTPermission
extends java.security.BasicPermission {
// Constructors
public AWTPermission(String);
public AWTPermission(String, String);
}
See also: BasicPermission, Permission
Class java.io.FilePermission | |
|
| |
This class represents permission to read, write, delete, or execute
files. The name encapsulated in this permission is the name of the
file; the string "<<ALL_FILES>>" represents
all files, while an asterisk represents all files in a directory and
a hyphen represents all files that descend from a directory. The
actions for this permission are read, write, execute, and delete.
Class Definition
public final class java.io.FilePermission
extends java.security.Permission
implements java.io.Serializable {
// Constructors
public FilePermission(String, String);
// Instance Methods
public boolean equals(Object);
public String getActions();
public int hashCode();
public boolean implies(Permission);
public PermissionCollection newPermissionCollection();
}
See also: Permission
Class java.io.SerializablePermission | |
|
| |
This class represents permission to perform specific operations
during object serialization--specifically, whether or not object
substitution may occur during serialization. As all basic
permissions, there are no actions associated with this class, which
has one valid name: enableSubstitution.
Class Definition
public final class java.io.SerializablePermission
extends java.security.BasicPermission {
// Constructors
public SerializablePermission(String);
public SerializablePermission(String, String);
}
See also: BasicPermission, Permission
Class java.lang.ClassLoader | |
|
| |
This class is the basis for loading a class dynamically in Java. For
historical reasons, it appears in this package, but it is recommended
that all new class loaders subclass the
SecureClassLoader class in the
java.security package instead of using this
class. Loading a class explicitly may be done with the
loadClass() method of this class (though classes
are usually simply loaded as needed).
Class Definition
public abstract class java.lang.ClassLoader
extends java.lang.Object {
// Constructors
protected ClassLoader();
protected ClassLoader(ClassLoader);
// Class Methods
public static ClassLoader getSystemClassLoader();
public static URL getSystemResource(String);
public static InputStream getSystemResourceAsStream(String);
public static Enumeration getSystemResources(String);
// Instance Methods
public ClassLoader getParent();
public URL getResource(String);
public InputStream getResourceAsStream(String);
public final Enumeration getResources(String);
public Class loadClass(String);
// Protected Instance Methods
protected final Class defineClass(String, byte[], int, int);
protected final Class defineClass(byte[], int, int);
protected final Class defineClass(String, byte[], int, int,
ProtectionDomain);
protected Package definePackage(String, String, String, String,
String, String, String, URL);
protected Class findClass(String);
protected String findLibrary(String);
protected final Class findLoadedClass(String);
protected Class findLocalClass(String);
protected final Class findSystemClass(String);
protected Package getPackage(String);
protected Package[] getPackages();
protected synchronized Class loadClass(String, boolean);
protected final void resolveClass(Class);
protected final void setSigners(Class, Object[]);
}

Class java.lang.RuntimePermission | |
|
| |
This class represents permission to perform certain runtime
operations, such as executing other programs. Like all basic
permissions, runtime permissions have no actions.
Class Definition
public final class java.lang.RuntimePermission
extends java.security.BasicPermission {
// Constructors
public RuntimePermission(String);
public RuntimePermission(String, String);
}
See also: BasicPermission, Permission
Class java.lang.SecurityManager | |
|
| |
This class forms the primary interface to the security model of the
virtual machine; it is recommended for backwards compatibility that
access to that model occur through this class rather than by calling
the access controller directly. However, most of the methods of this
class simply call the access controller.
Class Definition
public class java.lang.SecurityManager
extends java.lang.Object {
// Variables
protected boolean inCheck;
// Constructors
public SecurityManager();
// Instance Methods
public void checkAccept(String, int);
public void checkAccess(Thread);
public void checkAccess(ThreadGroup);
public void checkAwtEventQueueAccess();
public void checkConnect(String, int);
public void checkConnect(String, int, Object);
public void checkCreateClassLoader();
public void checkDelete(String);
public void checkExec(String);
public void checkExit(int);
public void checkLink(String);
public void checkListen(int);
public void checkMemberAccess(Class, int);
public void checkMulticast(InetAddress);
public void checkMulticast(InetAddress, byte);
public void checkPackageAccess(String);
public void checkPackageDefinition(String);
public void checkPermission(Permission);
public void checkPermission(Permission, Object);
public void checkPrintJobAccess();
public void checkPropertiesAccess();
public void checkPropertyAccess(String);
public void checkRead(FileDescriptor);
public void checkRead(String);
public void checkRead(String, Object);
public void checkSecurityAccess(String);
public void checkSetFactory();
public void checkSystemClipboardAccess();
public boolean checkTopLevelWindow(Object);
public void checkWrite(FileDescriptor);
public void checkWrite(String);
public boolean getInCheck();
public Object getSecurityContext();
public ThreadGroup getThreadGroup();
// Protected Instance Methods
protected native int classDepth(String);
protected native int classLoaderDepth();
protected native ClassLoader currentClassLoader();
protected Class currentLoadedClass();
protected native Class[] getClassContext();
protected boolean inClass(String);
protected boolean inClassLoader();
}

Class java.lang.reflect.ReflectPermission | |
|
| |
This class represents the ability to obtain information via object
reflections; specifically, whether private and protected variables
and methods may be accessed through object reflection. As all basic
permissions, this permission carries no actions; it has a single
name: access.
Class Definition
public final class java.lang.reflect.ReflectPermission
extends java.security.BasicPermission {
// Constructors
public ReflectPermission(String);
public ReflectPermission(String, String);
}
See also: BasicPermission, Permission
Class java.net.NetPermission | |
|
| |
This class represents the ability to work with multicast sockets and
the ability to use the authenticator classes. As all basic
permissions, this class carries no actions.
Class Definition
public final class java.net.NetPermission
extends java.security.BasicPermission {
// Constructors
public NetPermission(String);
public NetPermission(String, String);
}
See also: BasicPermission, Permission
Class java.net.SocketPermission | |
|
| |
This class represents the ability to work with certain sockets. The
name of this permission is constructed from the hostname or IP
address of the machine on the other end of the socket and the port
number; either portion of the name is subject to wildcard matching.
Valid actions for this class include connect, accept, and listen.
Class Definition
public final class java.net.SocketPermission
extends java.security.Permission
implements java.io.Serializable {
// Constructors
public SocketPermission(String, String);
// Instance Methods
public boolean equals(Object);
public String getActions();
public int hashCode();
public boolean implies(Permission);
public PermissionCollection newPermissionCollection();
}

Class java.net.URLClassLoader | |
|
| |
This class provides a concrete class loader that may be used to load
classes from one or more URLs (either http-based or file-based URLs).
Since it is a secure class loader, classes loaded from a URL class
loader will be fully integrated into the access controller's
security model.
Class Definition
public class java.net.URLClassLoader
extends java.security.SecureClassLoader {
// Constructors
public URLClassLoader(URL[], ClassLoader);
public URLClassLoader(URL[]);
public URLCLassLoader(URL[], ClassLoader, URLStreamHandlerFactory);
// Class Methods
public static URLClassLoader newInstance(URL[]);
public static URLClassLoader newInstance(URL[], ClassLoader);
// Instance Methods
public URL findResource(String);
public Enumeration findResources(String);
public URL[] getURLs();
// Protected Instance Methods
protected void addURL(URL);
protected Package definePackage(String, Manifest, URL);
protected Class findClass(String);
protected PermissionCollection getPermissions(CodeSource);
}

Class java.rmi.RMISecurityManager | |
|
| |
The RMI security manager provides a security manager that is suitable
for many RMI servers. It provides the ability for RMI applications to
make socket-based connections to each other, and otherwise follows
the default security manager implementation.
Class Definition
public class java.rmi.RMISecurityManager
extends java.lang.SecurityManager {
// Constructors
public RMISecurityManager();
// Instance Methods
}
See also: SecurityManager
Class java.rmi.server.RMIClassLoader | |
|
| |
While not a traditional class loader, this class allows classes to be
loaded via the same mechanics as a class loader: the
loadClass() method may be called to load a class
explicitly, and this class will also be used to load all subsequent
classes required by the target class. This class loader will only
load classes from the URL specified by the
java.rmi.server.codebase property. The internal
class loader used by this class is a secure class loader, so the
security model of the access controller will be used by classes
loaded in this manner.
Class Definition
public class java.rmi.server.RMIClassLoader
extends java.lang.Object {
// Class Methods
public static Object getSecurityContext(ClassLoader);
public static Class loadClass(String);
public static Class loadClass(String, String);
public static Class loadClass(URL, String);
}
See also: ClassLoader, SecureClassLoader
Class java.util.PropertyPermission | |
|
| |
This class represents the ability to read or write properties. The
name of a property permission is the name of the property itself; the
action for a property permission is either set or get.
Class Definition
public final class java.util.PropertyPermission
extends java.security.BasicPermission {
// Constructors
public PropertyPermission(String, String);
// Instance Methods
public boolean equals(Object);
public String getActions();
public int hashCode();
public boolean implies(Permission);
public PermissionCollection newPermissionCollection();
}
