Definition from Wiktionary, the free dictionary
constructor (plural constructors)
- A person who, or thing that constructs
- (object-oriented programming) A class method that creates and initializes each instance of an object
- (automotive) A company or individual who builds racing vehicles. In Formula One, constructor status is strictly defined by the rules, but in other motorsports the term is merely a descriptor. Depending on the racing rules, some constructors (e.g. Cosworth) may provide vehicles to racing teams who are not themselves constructors, while others are both teams and constructors (Ducati Corse, Scuderia Ferrari).
