Daniel :
How can I inherit from another class without adopting the parent type?
For example I want to be able to let Car
adopt all methods and properties of Vehicle
without being recognized as an Object of type Vehicle
.
Is there a convenient way of doing this in Java without duplicating all methods and properties?
Micha Wiedenmann :
It depends on your definition of convenient. You are a looking for Forwarding/Composition/Aggregation, essentially:
class B {
A a;
T foo() { return a.foo(); }
}
Which implies that all methods defined in A
need to be duplicated in B
.
This often comes up in discussion about Inheritance vs. Aggregation.
