CustomAttribute

public sealed interface ClassFileElement
permits AttributedElement, CompoundElement<E>, Attribute<A>, ClassElement, CodeElement, FieldElement, MethodElement

Marker interface for structures with special capabilities in the class file format. AttributedElement indicates a structure has Attributes. CompoundElement indicates a structure can be viewed as a composition of member structures, whose memberships are marked by ClassElement, MethodElement, FieldElement, or CodeElement.

Membership Elements

ClassModel, MethodModel, FieldModel, and CodeModel each has a dedicated interface marking its member structures: ClassElement, MethodElement, FieldElement, and CodeElement. They can be supplied to a ClassBuilder, a MethodBuilder, a FieldBuilder, or a CodeBuilder to be included as members of the built model. Unless otherwise specified, these structures are delivered during the traversal of the corresponding models. Some of these elements may appear at most once or exactly once in the traversal of the models; such elements have special treatment by ClassFileBuilder and are specified in their modeling interfaces. If such elements appear multiple times during traversal, the last occurrence should be used and all previous instances should be discarded.

These membership element marker interfaces are sealed; future versions of the Java SE Platform may define new elements to the sealed hierarchy when the class file format for the Java Platform evolves. Using an exhaustive pattern matching switch over these hierarchies indicates the user only wish the processing code to run on a specific version of Java Platform, and will fail if unknown new elements are encountered.
