Delphi: Call a function whose name is stored in a string -

-

is possible call function name stored in string in delphi?

please give more details on trying achieve.

as far know:

  • it not possible call random function that.
  • for class , object functions (myobject.function) can done rtti, it's lot of work.
  • if need call 1 particular type of functions (say, function(integer, integer): string), it's lot easier.

for last one, declare function type, function pointer , cast this:

type   tmyfunctype = function(a: integer; b: integer): string of object;    tmyclass = class   published     function func1(a: integer; b: integer): string;     function func2(a: integer; b: integer): string;     function func3(a: integer; b: integer): string;   public     function call(methodname: string; a, b: integer): string;   end;  function tmyclass.call(methodname: string; a, b: integer): string; var m: tmethod; begin   m.code := self.methodaddress(methodname); //find method code   m.data := pointer(self); //store pointer object instance   result := tmyfunctype(m)(a, b); end;  {...}  //use var myclass: tmyclass; begin   myclass := tmyclass.create;   myclass.call('func1', 3, 5);   myclass.call('func2', 6, 4);   myclass.destroy; end.
