ClassElement class abstract

An element that represents a class or a mixin. The class can be defined by either a class declaration (with a class body), a mixin application (without a class body), a mixin declaration, or an enum declaration.

Clients may not extend, implement or mix-in this class.

Return a list containing all of the accessors (getters and setters) declared in this class.
no setterinherited

no setterinherited
augmented → AugmentedClassElement
