Examples of com.google.dart.engine.element.PropertyAccessorElement

com.google.dart.engine.element.PropertyAccessorElement
The interface {@code PropertyAccessorElement} defines the behavior of elements representing agetter or a setter. Note that explicitly defined property accessors implicitly define a synthetic field. Symmetrically, synthetic accessors are implicitly created for explicitly defined fields. The following rules apply:
- Every explicit field is represented by a non-synthetic {@link FieldElement}.
- Every explicit field induces a getter and possibly a setter, both of which are represented by synthetic {@link PropertyAccessorElement}s.
- Every explicit getter or setter is represented by a non-synthetic {@link PropertyAccessorElement}.
- Every explicit getter or setter (or pair thereof if they have the same name) induces a field that is represented by a synthetic {@link FieldElement}.
