Thu Feb 5 10:12:00 1998 Richard Frith-Macdonald <richard@brainstorm.co.uk>
* src/NSConcreteNumber.m: Defined preprocessor values to handle
'promotion' of numeric types and added private methods to support
this. Modified ([-compare:]) to promote numeric values so that
comparisons work as expected. Implemented ([-isEqualToNumber:]),
Implemented ([-description]) and partially ([-descriptionWithLocale:])
Implemented ([-hash]) so that numbers which compare the same also
has the same (so we can use NSNumbers as dictionary keys).
* src/NSData.m: Added non-openstep method ([-relinquishAllocatedBytes])
to ask a data object to hand over it's malloced buffer.
* src/NSNumber.m: Added initialisation methods specified in Rhapsody
documentation.
* src/NSString.m: ([-dataUsingEncoding:allowLossyConversion:]) made
tiny change for efficiency - moving test outside loop - perhaps the
compiler would have optimised it anyway.
* src/Port.m: Modified initialisaers to test for failure to create
NSData objects and return nil as appropriate.
* src/TcpPort.m: ([+newForReceivingFromPortNumber:]) release newly
created port before raising exceptions.
In both ([-invalidate]) methods we remove the port from the various
maps before doing anything else so that invalid ports can't be found
by accident during the invalidation process.
* src/UnixFileHandle.m: ([-readDataOfLength:]) fixed problem with
data object causing read value to be overwritten with nuls.
* src/include/NSData.h: Added ([-relinquishAllocatedBytes])
* src/NSValue.h: Added initialisation methods for NSNumber and
([-isEqualToNumber:]) method.
