org.eclipse.jdt.core.dom.StructuralPropertyDescriptor
Abstract base class for property descriptors of AST nodes. There are three kinds of properties:
- simple properties ( {@link SimplePropertyDescriptor}) - properties where the value is a primitive (int, boolean) or simple (String, InfixExprsssion.Operator) type other than an AST node; for example, the identifier of a {@link SimpleName}
- child properties ( {@link ChildPropertyDescriptor}) - properties whose value is another AST node; for example, the name of a {@link MethodDeclaration}
- child list properties ( {@link ChildListPropertyDescriptor}) - properties where the value is a list of AST nodes; for example, the statements of a {@link Block}
@since 3.0 @noextend This class is not intended to be subclassed by clients.
