Interface CodeAttribute
- All Superinterfaces:
Attribute<CodeAttribute>,AttributedElement,ClassFileElement,CodeModel,CompoundElement<CodeElement>,Iterable<CodeElement>,MethodElement
Models the
Code attribute (JVMS 4.7.3), 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.
