Example
abstract class Department {
constructor(public name: string) {}
printName(): void {
print("Department name: " + this.name);
}
abstract printMeeting(): void; // must be implemented in derived classes
}
class AccountingDepartment extends Department {
constructor() {
super("Accounting and Auditing"); // constructors in derived classes must call super()
}
printMeeting(): void {
print("The Accounting Department meets each Monday at 10am.");
}
generateReports(): void {
print("Generating accounting reports...");
}
}
function main() {
let department: Department; // ok to create a reference to an abstract type
department = new AccountingDepartment(); // ok to create and assign a non-abstract subclass
department.printName();
department.printMeeting();
//department.generateReports(); // error: department is not of type AccountingDepartment, cannot access generateReports
}
Run
tsc --emit=jit example.ts
Result
Department name: Accounting and Auditing
The Accounting Department meets each Monday at 10am.
Compile as JIT
