void	addException(Class type) Add an exception to those thrown by this method.
void	addException(String type) Add an exception type to those thrown by this method.
void	clear() Clear this method of all exception declarations.
BCClass[]	getExceptionBCs() Return bytecode for the exception types of this method, or an empty array if none.
int[]	getExceptionIndexes() Return the indexes in the class ConstantPool of the ClassEntrys for the exception types thrown by this method, or an empty array if none.
String[]	getExceptionNames() Return the names of the exception types for this method, or an empty array if none.
Class[]	getExceptionTypes() Return the Class objects for the exception types for this method, or an empty array if none.
BCMethod	getMethod() Return the owning method.
boolean	removeException(BCClass type) Remove an exception thrown by this method.
boolean	removeException(Class type) Remove an exception thrown by this method.
boolean	removeException(String type) Remove an exception type thrown by this method.
void	setExceptionIndexes(int[] exceptionIndexes) Set the indexes in the class ConstantPool of the ClassEntrys for the exception types thrown by this method.
void	setExceptions(BCClass[] exceptions) Set the checked exceptions thrown by this method.
