Operations define the behaviors of the object.
While there are lots of different behaviors, they can often be broken down into four main categories.
- Those that manipulate data in some way. i.e. change a password
- Those that compute something. i.e. calculate the pay rate
- Those that check on a state of an object. i.e. is the status active
- Those that monitor the object for the occurrence of a controlling event. i.e. did an alarm trigger.
Those that manipulate data often have a set in their function name. Such as setPassword(). Those that check the state of an object usually return a boolean value, and use the is prefix, such as isActive().
Those that monitor or compute data should have meaningful names that help describe the function that they will be performing.
