* 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 * using a depth state structure to allow incremental parsing * v0.1 * + first release *) {$IFDEF FPC} {$MODE OBJFPC}{$H+} {$ENDIF} {$DEFINE SUPER_METHOD} {$DEFINE WINDOWSNT_COMPATIBILITY} {$DEFINE DEBUG} // track memory leack unit superobject;
