Class ExceptionSet
java.lang.Object
edu.umd.cs.findbugs.ba.type.ExceptionSet
Class for keeping track of exceptions that can be thrown by an instruction.
We distinguish explicit and implicit exceptions. Explicit
exceptions are explicitly declared, thrown, or caught. Implicit exceptions
are runtime faults (NPE, array out of bounds) not explicitly handled by the
user code.
