-2002-09-06 Miguel de Icaza <miguel@ximian.com>
-
- * Encoding.cs (UTF8, Unicode): Create with a preamble, that is
- what the Microsoft version does.
-
- (UnixConsoleEncoding): New internal method, used to get the
- encoding, in the future, this should pull the locale, map to
- charset and then code page.
-
-Wed Sep 4 14:01:25 CEST 2002 Paolo Molaro <lupus@ximian.com>
-
- * Encoding.cs: use icall to get default codepage.
- * DefaultEncoding.cs: remove useless class.
-
-Mon Aug 26 16:44:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
-
- * *.cs: change to conform to mono coding style.
-
-2002-08-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
-
- * ASCIIEncoding.cs:
- * Decoder.cs:
- * Encoder.cs:
- * Encoding.cs:
- * UTF7Encoding.cs:
- * UTF8Encoding.cs:
- * UnicodeEncoding.cs: added Serializable attribute.
-
-2002-08-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
-
- * StringBuilder.cs: improved performace by using String.InternalCopyTo
- instead of using ToCharArray all over the place (more that 50% of
- speed improvement when using Append).
-
-Wed Aug 21 20:02:04 CEST 2002 Paolo Molaro <lupus@ximian.com>
-
- * *.cs: imported the code donated by Rhys Weatherley
- <rweather@southern-storm.com.au>.
-
-2002-08-18 Dick Porter <dick@ximian.com>
-
- * Encoding.cs: Make GetString() return a useful representation of
- the bytes, rather than "System.Char[]"
-
-2002-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>
-
- * StringBuilder.cs: added IndexerName to indexer.
-
-2002-08-01 Jason Diamond <jason@injektilo.org>
-
- * Encoding.cs: Use GetByteCount instead of GetMaxByteCount when
- converting chars to bytes.
-
-2002-07-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
-
- * StringBuilder.cs: updated comments. MaxCapacity always returns
- Int32.MaxValue.
-
-2002-06-21 Gonzalo Paniagua Javier <gonzalo@ximian.com>
-
- * StringBuilder.cs: implemented AppendFormat methods using
- String.Format. Thanks Paolo!
-
- This makes xsp generate correct C# output in linux :-). I still need
- to do more testing, though.
-
-Mon Jun 3 12:58:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
-
- * ASCIIEncoding.cs: fixed handling of 0 bytecount.
-
-2002-05-19 Martin Baulig <martin@gnome.org>
-
- * Encoder.cs (IConvEncoder.GetByteCount, IConvEncoder.GetBytes):
- Added exception handling.
-
- * Decoder.cs (IConvDecoder.GetCharCount, IConvDecoder.GetChars):
- Added exception handling.

-
-2002-03-21 Mike Kestner <mkestner@speakeasy.net>

- * ASCIIEncoding.cs : Fix off by one error in Get(Char|Byte)Count.
-
-Thu Mar 21 17:38:19 CET 2002 Paolo Molaro <lupus@ximian.com>
-
- * StringBuilder.cs: no need to intern the string returned by ToString().
-
-2002-03-17 Mike Kestner <mkestner@speakeasy.net>
-
- * ASCIIEncoding.cs: Implement all the overridden methods. No longer
- dependent on iconv icalls.
- * Encoding.cs: Fix count bugs in GetBytes and GetChars. Add virtual
- to GetBytes.
-
-Wed Mar 13 00:26:29 CET 2002 Paolo Molaro <lupus@ximian.com>
-
- * StringBuilder.cs: make ToString() return a interned string, this
- seems to be required to make switch on string work.
-
-Fri Mar 8 17:29:58 CET 2002 Paolo Molaro <lupus@ximian.com>
-
- * StringBuilder.cs: make Append(char) do the smart thing.
-
-2002-01-05 Ravi Pratap <ravi@ximian.com>
-
- * ASCIIEncoding.cs, Encoding.cs, UTF7Encoding.cs,
- UnicodeEncoding.cs: MonoTODO attribute marking.

-
-2001-10-29 Nick Drochak <ndrochak@gol.com>
-
- * StringBuilder.cs: Throw exceptions when constructor paramter(s) are
- invalid. Just like MS does (as best as I can tell).
-
- Tests for these exceptions are now added to the unit tests as well.
-
-2001-10-25 Nick Drochak <ndrochak@gol.com>
-
- * StringBuilder.cs: Throw exception if they try to make a StringBuilder
- whose capacity is greater than the MaxCapacity.
-
- I added some tests for the constructors and the above exception. More
- coming soon.
-
-2001-10-23 Nick Drochak <ndrochak@gol.com>
-
- * StringBuilder.cs: Refactored constructor code into just one
- constructor. All the other construtors call it. Also supplied missing
- constructors so the class has all those in the spec.
-
- Added the MaxCapacity property as well, however this needs to be
- completed to return a value is related to the available system memory.
-
-2001-10-07 Miguel de Icaza <miguel@ximian.com>
-
- * Encoding.cs, UTF8Encoding.cs, UTF7Encoding.cs, ASCIIEncoding.cs,
- UnicodeEncoding.cs: Corrected API.
-
- * UTF8Encoding.cs: Checked in changes from Rafael.
-
-2001-08-28 Dietmar Maurer <dietmar@ximian.com>
-
- * UTF8Encoding.cs: impl. clumsy GetBytes
-
-2001-07-16 Marcin Szczepanski <marcins@zipworld.com.au>

-
- * StringBuilderTest.cs: Implement Test suite.
-
-2001-07-12 Marcin Szczepanski <marcins@zipworld.com.au>
-
- * StringBuilder.cs: Implemented.
-
- The only methods left unimplemented are the AppendFormat( ... )
- ones just because it's probably better to wait until some of the
- Format related classes are implemented. I've put that as a TODO
- comment at the top and created the methods with a "nop" body.
-
-2001-06-26 Sean MacIsaac <macisaac@ximian.com>
-
- * UnicodeEncoding.cs: Members added so that a clean compile is
- possible.
-
- * ASCIIEncoding.cs: Members added so that a clean compile is
- possible.
-
- * UTF7Encoding.cs: Members added so that a clean compile is
- possible.
-
- * UTF8Encoding.cs: Members added so that a clean compile is
- possible.
-
- * Encoding.cs: All public members included. Most members
- unimplemented.
