xml::sax::exception(3)
NAME
XML::SAX::Exception - Exception classes for XML::SAX
SYNOPSIS
throw XML::SAX::Exception::NotSupported(
Message => "The foo feature is not supported",
);
DESCRIPTION
This module is the base class for all SAX Exceptions,
those defined in the spec as well as those that one may
create for one's own SAX errors.
- There are three subclasses included, corresponding to
those of the SAX spec: - XML::SAX::Exception::NotSupported
XML::SAX::Exception::NotRecognized
XML::SAX::Exception::Parse - Use them wherever you want, and as much as possible when
you encounter such errors. SAX is meant to use exceptions
as much as possible to flag problems.
CREATING NEW EXCEPTION CLASSES
- All you need to do to create a new exception class is:
- @XML::SAX::Exception::MyException::ISA = ('XML::SAX::Ex
- ception')
- The given package doesn't need to exist, it'll behave cor
rectly this way. If your exception refines an existing
exception class, then you may also inherit from that
instead of from the base class.
THROWING EXCEPTIONS
- This is as simple as exemplified in the SYNOPSIS. In fact,
there's nothing more to know. All you have to do is: - throw XML::SAX::Exception::MyException( Message =>
- 'Something went wrong' );
- and voila, you've thrown an exception which can be caught
in an eval block.
