overloaded operator
operacijos ženklo daugiareikšmiškumas statusas T sritis informatika apibrėžtis ↑Operacijos ženklo vartojimas daugiau negu viena prasme. Pavyzdžiui pliuso ženklu + žymima sudėties ir eilučių sujungimo operacija. Daugiareikšmiškumas yra leistinas, jeigu iš konteksto galima vienareikšmiškai nustatyti konkretaus ženklo reikšmę. Tas kontekstas dažniausiai būna tuo ženklu pažymėtos operacijos operandų skaičius ir jų tipai. Programavime yra skirtingų vienodai vadinamų aritmetinių operacijų dėl to, kad jos atliekamos su įvairių tipų skaičiais (pvz., realiaisiais ir sveikaisiais). Dėl to tas pats ženklas (pvz., pliusas) žymi kelias skirtingas aritmetines operacijas. atitikmenys: angl. overloaded operator ryšiai: dar žiūrėkoperacijos ženklas
