inheritance chainの例文

• Note that, so far, the metaclass inheritance chain exactly follows that of the class inheritance chain.
• Note that, so far, the metaclass inheritance chain exactly follows that of the class inheritance chain.
• Because methods may be defined several steps down the inheritance chain, a dynamic lookup can be an expensive operation.
• Hence, at any given level in the inheritance chain, there can be at most one implementation of any method.
• The reason for this is that such languages have at most one implementation of any method at any level in the inheritance chain regardless of the repetition or placement of methods.
• In other languages, a similar effect could be achieved at compile-time with a long linear chain of implementation inheritance, but with the disadvantage compared to Scala that one linear inheritance chain would have to be declared for each possible combination of the mix-ins.
• If the button uses the default font, accessing its font " slot " ( i . e ., property or member variable ) will return a value that is actually stored in ROM; the button instance in RAM does not have a value in its own font slot, so the prototype inheritance chain is followed until a value is found.
• Interfaces are like abstract base classes that specify method signatures without implementing any behavior . ( " Pure " interfaces such as the ones in Java up to version 7 do not permit any implementation or instance data in the interface . ) Nevertheless, even when several interfaces declare the same method signature, as soon as that method is implemented ( defined ) anywhere in the inheritance chain, it overrides any implementation of that method in the chain above it ( in its superclasses ).
