New protectionDomain field. (forName): Add initialize parameter. Fixes declaration to comply with JDK spec. * java/lang/natClass.cc (forName): Correct declaration of the three-arg variant. Honour "initialize" flag. (getProtectionDomain0): New method. * java/lang/Class.java: Fix forName() declaration. (getPackage): New method based on Classpath implementation. (getProtectionDomain0): New native method decl. (getProtectionDomain): New method. * java/lang/ClassLoader.java (getParent): Now final. (definedPackages): New field. (getPackage): New. (defineClass): New variant with protectionDomain argument. (definePackage): New. (getPackages): New. (findSystemClass): Now final. (getSystemResourceAsStream): Remove redundant "final" modifier. (getSystemResource): Remove redundant "final" modifier. (getResources): Now final. (protectionDomainPermission): New static field. (unknownProtectionDomain): Ditto. (defaultProtectionDomain): Ditto. (getSystemClassLoader): Now non-native. * java/util/ResourceBundle.java (tryGetSomeBundle): Use the correct arguments for Class.forName(). * java/lang/Package.java: New file. * gnu/gcj/runtime/VMClassLoader.java (getVMClassLoader): Removed. (instance): Static initialize singleton. (findClass): Override this, not findSystemClass. * java/lang/natClassLoader.cc (defineClass0): Set class's protectionDomain field as specified. (getSystemClassLoader): Removed. (findClass): Renamed from findSystemClass. Call the interpreter via URLClassLoader.findClass if loading class via dlopen fails. * java/security/*.java: java.security import/merge with Classpath. * java/security/acl/*.java: Likewise. * java/security/interfaces/*.java: Likewise. * java/security/spec/*.java: Likewise. * java/net/NetPermission.java: Likewise. * java/net/SocketPermission.java: Likewise. * gnu/java/security/provider/DefaultPolicy.java: Likewise. * Makefile.am: Add new classes. * Makefile.in: Rebuilt. * gcj/javaprims.h: CNI namespace rebuild. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@41543 138bc75d-0d04-0410-961f-82ee72b054a4 --- libjava/java/security/acl/Acl.java | 138 +++++++++++++++++++++ libjava/java/security/acl/AclEntry.java | 132 ++++++++++++++++++++ .../java/security/acl/AclNotFoundException.java | 46 +++++++ libjava/java/security/acl/Group.java | 79 ++++++++++++ libjava/java/security/acl/LastOwnerException.java | 47 +++++++ libjava/java/security/acl/NotOwnerException.java | 49 ++++++++ libjava/java/security/acl/Owner.java | 84 +++++++++++++ libjava/java/security/acl/Permission.java | 56 +++++++++ 8 files changed, 631 insertions(+) create mode 100644 libjava/java/security/acl/Acl.java create mode 100644 libjava/java/security/acl/AclEntry.java create mode 100644 libjava/java/security/acl/AclNotFoundException.java create mode 100644 libjava/java/security/acl/Group.java create mode 100644 libjava/java/security/acl/LastOwnerException.java create mode 100644 libjava/java/security/acl/NotOwnerException.java create mode 100644 libjava/java/security/acl/Owner.java create mode 100644 libjava/java/security/acl/Permission.java (limited to 'libjava/java/security/acl') diff --git a/libjava/java/security/acl/Acl.java b/libjava/java/security/acl/Acl.java new file mode 100644 index 00000000000..e5a3e088faa --- /dev/null +++ b/libjava/java/security/acl/Acl.java @@ -0,0 +1,138 @@ +/* Acl.java -- An access control list + Copyright (C) 1998 Free Software Foundation, Inc. + +This file is part of GNU Classpath. + +GNU Classpath is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2, or (at your option) +any later version. + +GNU Classpath is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
