The flexible pads are called base-isolators, whereas the structures protected by means of these devices are called base-isolated buildings. The main feature of the base isolation technology is that it introduces flexibility in the structure.
Mutators. A mutator is a method that can modify an object. In the simplest case, a mutator just assigns a new value to one of the fields. In general, a mutator performs some computation and modifies any number of fields.Sometimes, accessors are called 'getter' methods and mutators are called 'setter' methods.n accessor is a method that accesses the contents of an object but does not modify that object. In the simplest case, an accessor just returns the value of one of the fields. In general, an accessor performs some computation using the fields as long as that computation does not modify any of the fields.
