Interface JExceptionHandler

All Superinterfaces:

JClassFileItem, JObject

All Known Implementing Classes:

DefaultJExceptionHandler

public interface JExceptionHandler
extends JClassFileItem

A JExceptionHandler represents an entry in the exception_table of a Code attribute. A such entry describes one exception handler in the byte code array of a method (i.e. a try/catch statement). It contains :

• the ranges in the byte code array at which the exception handler is active,
• the start of the exception handler into the byte code array,
• an index into the constant pool indicating a class of exceptions that this exception handler is designated to catch.

int	getHandlerPC() Returns the start of this exception handler into the byte code array.
int	getStartPC() Returns the start position in the byte code array at which the exception handler is active.
void	setCatchType(java.lang.String name) Sets the index into the constant pool indicating the class of exceptions specified by name that a method is designated to catch.
void	setCatchTypeIndex(int index) Sets the index into the constant pool indicating a class of exceptions that a method is designated to catch.
void	setEndPC(int endPC) Sets the end position in the byte code array at which the exception handler is active.
void	setHandlerPC(int handlerPC) Sets the start of this exception handler into the byte code array.
void	setStartPC(int startPC) Sets the start position in the byte code array at which the exception handler is active.
