Represents a program element such as a module, package, class, or method. Each element represents a static, language-level construct (and not, for example, a runtime construct of the virtual machine).
Elements should be compared using the equals(Object)
method. There is no guarantee that any particular element will
always be represented by the same object.
To implement operations based on the class of an
Element object, either use a visitor or
use the result of the getKind method. Using
instanceof is not necessarily a reliable idiom for
determining the effective class of an object in this modeling
hierarchy since an implementation may choose to have a single object
implement multiple Element subinterfaces.
