Re: Unit-übergreifende Vorwärtsdeklaration von Klassen?

Hi!

Oh, vielen Dank. Wenn das wirklich so funktioniert sollte ich das mal umschreiben!

Das mit dem Code sehe ich ein, hier mal etwas realer Code. Dann ist vielleicht auch klarer wodurch diese Abhängigkeiten entstehen:

Delphi-Quellcode:
unit NeuronNetwork;

interface

Type
  TNetColors = (colBG, colHintBG, colHintBorder, colReady, colTriggered, colSleeping,
                colAccumulate, colForget, colMemory);

  TTextPos = (tpLeft, tpRight, tpTop, tpBottom);

  TNeuronClass = (ncHardLimit, ncPWLinear);

  TNeuronType = (ntAccumulate, ntForget, ntMemory);

  TCalculation = (cnLinear, cnQuadratic, cnNegQuad, cnPosQuad);

  TNeuroTransmitter = (ntBias, ntPositive, ntNegative, ntPosPWL, ntNegPWL,
                       ntThreshold, ntIntensify, ntExtenuate,
                       ntPulseUp, ntPulseDown, ntClear, ntSleep, ntAwake);

Ok, das ist alleine mal der Interface-Teil. Der Code für all die Prozeduren und Funktionen kommt hinzu- unhandlich ohne Ende !
