High Quality Content by WIKIPEDIA articles! Type generalization is a technique commonly used in refactoring. The idea is to draw on the benefits of object-orientation and make more-generalized types, thus enabling more code sharing, leading to better maintainability as there is less code to write. Too-general code can, however, become completely useless, leading to spaghetti code doing effectively nothing. Type generalization refers to making more general or more abstract some subset of the traits of a specific type. A superclass has wider use than a specific subclass, and so is more 'general'.
