Examples of IDefinition

org.apache.flex.compiler.definitions.IDefinition
The base class for all definitions.
A definition is something in source code that can be referred to by name: a package, namespace, class, interface, function, getter, setter, parameter, variable, constant, event, style, or effect.

Each definition has
- a source location;
- an optional list of metadata annotations;
- a namespace reference indicating its visibility, such as public;
- a set of flags indicating modifiers such as static or override;
- a base, or unqualified, name;
- a type reference (which may be null for some types of definitions.
Specific types of definitions of course store additional information. For example, a class definition stores a reference to the class it extends and references to the interfaces that it implements.
Definitions refer to other definitions indirectly, by name, using an IReference. See the references subpackage for an explanation of this design.
