[multiple changes] 2005-02-21 Bryce McKinlay <mckinlay@redhat.com> Merge serialization from GNU Classpath. * gcj/method.h: Add missing #includes. * java/io/ObjectInputStream.java (readClassDescriptor): Check for primitive class IDs on the stream here... (resolveClass): ...not here. * java/io/ObjectStreamField.java: Use VMObjectStream class calls to set fields. * java/io/VMObjectStreamClass.java (setDoubleNative, setFloatNative, setLongNative, setIntNative, setShortNative, setCharNative, setByteNative, setBooleanNative, setObjectNative): New native methods. * java/io/natVMObjectStreamClass.java (setDoubleNative, setFloatNative, setLongNative, setIntNative, setShortNative, setCharNative, setByteNative, setBooleanNative, setObjectNative): Implement them. * java/io/natObjectInputStream.cc (allocateObject): Add new parameters from Classpath's version. Use _Jv_FromReflectedConstructor(). Call the constructor here. (callConstructor): Removed. (getCallersClassLoader): Removed. * java/lang/reflect/Field.java (setByte, setShort, setInt, setLong, setFloat, setDouble, setChar, setBoolean): Add 'checkFinal' parameter to control whether setting final field values is permitted. Call getAddr() with checkFinal parameter instead of setAddr(). * java/lang/reflect/natField.cc (getType): Lookup and resolve field only if not done already. (getAddr): Add checkFinal parameter. Do the final field check only if checkFinal is set. (setAddr): Removed. 2005-02-21 Mark Wielaard <mark@klomp.org> # Fixes bug #11957 * java/io/ObjectInputStream.java (resolveClass): Don't check "void" twice. 2005-02-21 Mark Wielaard <mark@klomp.org> Fixes bug #11618. * java/io/ObjectInputStream.java (readClassDescriptor): Handle classes without a super class and us ObjectStreamClass.lookupForClassObject(). (resolveClass): Check for primitive types. (lookupClass): Return null when argument is null. 2005-02-21 Jeroen Frijters <jeroen@frijters.net> * java/io/ObjectInputStream.java (readObject): Fix to consume TC_ENDBLOCKDATA after readExternal. 2005-02-21 Jeroen Frijters <jeroen@frijters.net> * java/io/ObjectOutputStream.java (writeObject, callWriteMethod): Replaced reflection with accessing cached info in ObjectStreamClass. (getMethod): Removed. * java/io/ObjectStreamClass.java (findMethod): Added check to make sure the method found has the right modifiers. (cacheMethods): Added writeReplace and writeObject methods. (setFlags): Look at new writeObjectMethod field instead of doing reflection again. (writeReplaceMethod): New field. (writeObjectMethod): New field. 2005-02-21 Guilhem Lavaux <guilhem@kaffe.org> Jeroen Frijters <jeroen@frijters.net> * java/io/ObjectInputStream.java (newObject): Changed prototype. Get a constructor reflect object directly. (callConstructor): Removed. (allocateObject): Changed prototype. (readClassDescriptor): Build the constructor reflection directly. (readObject): Invoke newObject using the new prototype. * java/io/ObjectStreamClass.java (firstNonSerializableParent): Removed. (firstNonSerializableParentConstructor): Added. From-SVN: r95378
