Do not remove methods for the sake of efficiency - use inline methods instead. For example:
class Account { protected: int accountNumber; public: // an example inline method int getAccountNumber() { return accountNumber; } };
This is better than making the accountNumber
state public
,
retaining encapsulation. Inline is ignored with virtual
methods. We can provide
full access to a state through methods, rather than directly to the state by making it public, by
providing an accessor and a mutator. For example for the
accountNumber
state in the Account
class, these would look
like
int getAccountNumber(); //accessor void setAccountNumber(int newNumber); //mutator
The main advantage of this format is that access can be controlled to the accountNumber
state, so, if additional functionality is required at a later stage, it can be
achieved, without effecting the developers using the Account
class.
We can also declare standalone methods (global methods) to be inline, such as:
inline int account::getAccountNumber() { //etc }
