Class ExceptionHandlerMap
public
class
ExceptionHandlerMap
extends Object
This class provides a convenient way of determining the exception handlers
for instructions in a method. Essentially, it's a
a map of InstructionHandles to lists of CodeExceptionGen objects.
This class also maps instructions which are the start of exception handlers
to the CodeExceptionGen object representing the handler.

| Method Summary |
|---|
| CodeExceptionGen | getHandlerForStartInstruction(InstructionHandle start)
If the given instruction is the start of an exception handler,
get the CodeExceptionGen object representing the handler.
|
| List<CodeExceptionGen> | getHandlerList(InstructionHandle handle)
Get the list of exception handlers (CodeExceptionGen objects)
which are specified to handle exceptions for the instruction whose
handle is given. |
public ExceptionHandlerMap(MethodGen methodGen)
Constructor.
Parameters: methodGen the method to build the map for
public CodeExceptionGen getHandlerForStartInstruction(InstructionHandle start)
If the given instruction is the start of an exception handler,
get the CodeExceptionGen object representing the handler.
Parameters: start the instruction
Returns: the CodeExceptionGen object, or null if the instruction is not the
start of an exception handler
public List<CodeExceptionGen> getHandlerList(InstructionHandle handle)
Get the list of exception handlers (CodeExceptionGen objects)
which are specified to handle exceptions for the instruction whose
handle is given. Note that the handlers in the returned list
are
in order of priority, as defined in the method's exception handler
table.
Parameters: handle the handle of the instruction we want the exception handlers for
Returns: the list of exception handlers, or null if there are no handlers
registered for the instruction
