Interface CodeAttribute

All Superinterfaces:

Attribute<CodeAttribute>, AttributedElement, ClassFileElement, CodeModel, CompoundElement<CodeElement>, Iterable<CodeElement>, MethodElement, WritableElement<CodeAttribute>

All Known Implementing Classes:

BoundAttribute.BoundCodeAttribute, CodeImpl

public sealed interface CodeAttribute
extends Attribute<CodeAttribute>, CodeModel
permits BoundAttribute.BoundCodeAttribute

Models the Code attribute , appears on non-native, non-abstract methods and contains the bytecode of the method body. Delivered as a MethodElement when traversing the elements of a MethodModel.

The attribute does not permit multiple instances in a given location. Subsequent occurrence of the attribute takes precedence during the attributed element build or transformation.
