11.2.2 Planned features: OOP

• Object Oriented Extensions draft, Delphi; class; allow classes and object types to inherit from each other; <01BD7A3A.6B187A20.prucha@helicon.co.at>; obpascal.zip
• error/exception handling (Java, Delphi?) <01BD7A3A.6B187A20.prucha@helicon.co.at> (tc20000623)
• method pointers/procedural variables (procedure/function of object) (-> Delphi) ???
• destructor: reset VMT link to nil ???
• class is class (implemented in Pascal with Parent)
• BP compatible dynamic method dispatcher ?? ???
• New: Delphi syntax; Dispose?? (automatically?; set references automatically to nil) (-> FPC)
• --base-class=foo, --base-object=bar ???
• properties <01BD7A3A.6B187A20.prucha@helicon.co.at>, <16131.199805071354@potter.cc.keele.ac.uk>
• VMTs (also for local classes (EP modules???)!) in GPI files, written to assembler file by main program; --cfiles=foo: .s file with VMTs for C/assembler??? (also .h???)
• method overloading ??? ??
• interfaces (cf. OOE, Java); obj is interface (not so easy?) ???; variables of type pointer to more than one interface [and class] (also possible!); VMT problem with interfaces (my solution??? also with dynamic linking???)
• virtual constructors; in interfaces (load)???
• VMT: Children: list of pVMT
• VMT: object constants, class variables; virtual/static
• VMT: ClassID (64/128 bits?) default 0, error when duplicated, warning when 0 and inherited from class with <>0 ?, not allowed for abstract classes!; ClassName (also for abstract classes?); []; ProgrammerID, BaseClassID at beginning of unit (redeclarable?); find class by ClassID/ClassName (implementable in Pascal with Children); store in GPI: whether ClassID used, ClassName used, which classes are instantiated ???
