public interface ExceptionEvent extends LocatableEvent
exception request, an
event setcontaining an instance of this class will be added to the VM's event queue. If the exception is thrown from a non-native method, the exception event is generated at the location where the exception is thrown. If the exception is thrown from a native method, the exception event is generated at the first non-native location reached after the exception is thrown.
|Modifier and Type||Method and Description|
Gets the location where the exception will be caught.
Gets the thrown exception object.
Throwableor a subclass in the target VM.
ObjectReferencewhich mirrors the thrown object in the target VM.
If there are native methods in the call stack at the time of the exception, there are important restrictions to note about the returned catch location. In such cases, it is not possible to predict whether an exception will be handled by some native method on the call stack. Thus, it is possible that exceptions considered uncaught here will, in fact, be handled by a native method and not cause termination of the target VM. Furthermore, it cannot be assumed that the catch location returned here will ever be reached by the throwing thread. If there is a native frame between the current location and the catch location, the exception might be handled and cleared in that native method instead.
Note that the compiler can generate try-catch blocks in some cases
where they are not explicit in the source code; for example,
the code generated for
finally blocks can contain implicit try-catch blocks.
If such an implicitly generated try-catch is
present on the call stack at the time of the throw, the exception
will be considered caught even though it appears to be uncaught from
examination of the source code.
Locationwhere the exception will be caught or null if the exception is uncaught.
