Nova verze je online. Obsahuje precompilator trid pro spusteni v ramci MultiTask. Generuje OnNewWork, generuje metody pro volani bez Enqueue.
Priklad :
tIQDeploy_v4 = class(TObject) {class_MT}
published
{$I MT_onNewWork.inc}
procedure Load_Image(const id: integer; const item: iSuperObject; const fn: string); {gen_MT}
{$I MT_def.inc}
end;
implementation
{$I MT_impl.inc}
V tomto pripade vygeneruje precompilator metody :
procedure Load_Image_MT( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Last( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Low( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Normal( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_High( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_ASAP( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique_Last( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique_Low( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique_Normal( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique_High( const id : integer; const item : iSuperObject; const fn : string);
procedure Load_Image_MT_Unique_ASAP( const id : integer; const item : iSuperObject; const fn : string);
v te same tride. Prostym zavolanim _MT misto prime metody zaridite, ze se dana metoda spusti ve zvlastnim vlakne MultiTasku.
Metody _MT_XXX slouzi pro prime vlozeni do fronty dle pozadovane priority, tudiz je mozno velmi pekne ridit, co se kdy ma spustit apod
Metody _MT_Unique* slouzi pro vlozeni do fronty POUZE pokud stejna metoda SE STEJNYMI parametry jiz neni ve fronte, nebo aktualne provadena.
Precompilator je maximalne customizovatelny, v realu vygeneruje 3 soubory -
OnNewWork.inc (tuto metodu stale dokola spousti kazde vlakno MultiTasku, a ona rozhoduje co se vlastne ma spustit a zajisti spusteni),
MT_def.inc - definice pridavnych metod
MT_impl.inc - implementace prikazu pro vlozeni do fronty tasku.
Parametry (ci konfiguracnim souborem) je mozno urcite vicemene cokoliv od jmena tridy (pokud neni oznacen flagem viz vyse), pres suffix metod az po typ metod k vygenerovani.
Priklad spusteni v prebuild eventu lazarusu - ci jinde dle libosti :
MultiTask_PreCompiler.exe --configuration-file MultiTask_PreCompiler.cfg deploy_v4.pas
Konfiguracni soubor obsahuje napirklad nasledujici :
-mdf MT_definition.inc -mif MT_implementation.inc -onwf MT_onNewWork.inc -onw On_New_Work -lapm -lopm -npm -hpm -apm
