Interface ExceptionCatch
- All Superinterfaces:
- ClassFileElement,- CodeElement,- PseudoInstruction
A pseudo-instruction modeling an entry in the 
exception_table array
 of a Code attribute.  Catch (JVMS 3.12) and
 finally (JVMS 3.14) blocks in Java source code compile to exception
 table entries.  Delivered as a CodeElement when traversing the
 contents of a CodeModel.
 An exception table entry is composite:
ExceptionCatch(
    Label handler,
    Label tryStart,
    Label tryEnd,
    Optional<ClassEntry> catchType
)
