* CHANGES:
|
|
* v1.2
|
|
* + support of currency data type
|
|
* + right trim unquoted string
|
|
* + read Unicode Files and streams (Litle Endian with BOM)
|
|
* + Fix bug on javadate functions + windows nt compatibility
|
|
* + Now you can force to parse only the canonical syntax of JSON using the stric parameter
|
|
* + Delphi 2010 RTTI marshalling
|
|
* v1.1
|
|
* + Double licence MPL or LGPL.
|
|
* + Delphi 2009 compatibility & Unicode support.
|
|
* + AsString return a string instead of PChar.
|
|
* + Escaped and Unascaped JSON serialiser.
|
|
* + Missed FormFeed added \f
|
|
* - Removed @ trick, uses forcepath() method instead.
|
|
* + Fixed parse error with uppercase E symbol in numbers.
|
|
* + Fixed possible buffer overflow when enlarging array.
|
|
* + Added "delete", "pack", "insert" methods for arrays and/or objects
|
|
* + Multi parametters when calling methods
|
|
* + Delphi Enumerator (for obj1 in obj2 do ...)
|
|
* + Format method ex: obj.format('<%name%>%tab[1]%</%name%>')
|
|
* + ParseFile and ParseStream methods
|
|
* + Parser now understand hexdecimal c syntax ex: \xFF
|
|
* + Null Object Design Patern (ex: for obj in values.N['path'] do ...)
|
|
* v1.0
|
|
* + renamed class
|
|
* + interfaced object
|
|
* + added a new data type: the method
|
|
* + parser can now evaluate properties and call methods
|
|
* - removed obselet rpc class
|
|
* - removed "find" method, now you can use "parse" method instead
|
|
* v0.6
|
|
* + refactoring
|
|
* v0.5
|
|
* + new find method to get or set value using a path syntax
|
|
* ex: obj.s['obj.prop[1]'] := 'string value';
|
|
* obj.a['@obj.array'].b[n] := true; // @ -> create property if necessary
|
|
* v0.4
|
|
* + bug corrected: AVL tree badly balanced.
|
|
* v0.3
|
|
* + New validator partially based on the Kwalify syntax.
|
|
* + extended syntax to parse unquoted fields.
|
|
* + Freepascal compatibility win32/64 Linux32/64.
|
|
* + JavaToDelphiDateTime and DelphiToJavaDateTime improved for UTC.
|
|
* + new TJsonObject.Compare function.
|
|
* v0.2
|
|
* + Hashed string list replaced with a faster AVL tree
|
|
* + JsonInt data type can be changed to int64
|
|
* + JavaToDelphiDateTime and DelphiToJavaDateTime helper fonctions
|
|
* + from json-c v0.7
|
|
* + Add escaping of backslash to json output
|
|
* + Add escaping of foward slash on tokenizing and output
|
|
* + Changes to internal tokenizer from using recursion to
