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

com.google.dart.engine.element.Element
The interface {@code Element} defines the behavior common to all of the elements in the elementmodel. Generally speaking, the element model is a semantic model of the program that represents things that are declared with a name and hence can be referenced elsewhere in the code.
There are two exceptions to the general case. First, there are elements in the element model that are created for the convenience of various kinds of analysis but that do not have any corresponding declaration within the source code. Such elements are marked as being synthetic. Examples of synthetic elements include
- default constructors in classes that do not define any explicit constructors,
- getters and setters that are induced by explicit field declarations,
- fields that are induced by explicit declarations of getters and setters, and
- functions representing the initialization expression for a variable.
Second, there are elements in the element model that do not have a name. These correspond to unnamed functions and exist in order to more accurately represent the semantic structure of the program. @coverage dart.engine.element
