NAME
OpenFrame::WebApp::Error - base class for WebApp Errors.
SYNOPSIS
# meant to be sub-classed:
use OpenFrame::WebApp::Error::SomeClass;
# should export some error flags to your namespace
use Error qw( :try );
try {
throw OpenFrame::WebApp::Error::SomeClass( flag => eSomeError );
} catch OpenFrame::WebApp::Error::SomeClass with {
my $e = shift;
do { ... } if ($e->flag == eSomeError);
}DESCRIPTION
This is the base class for Error exceptions in OpenFrame-WebApp. It introduces an error flag to the Error module in an attempt to make localization easier.
Descriptive error flags should be exported from each subclass:
use base qw( Exporter OpenFrame::WebApp::Error );
our @EXPORT = qw( eSomethingBad );
use constant eSomethingBad => 'something.bad';The value of these constants can then be used as localization keys with the likes of Locale::Gettext or Locale::Maketext.
CONSTRUCTOR
new recognizes '-flag' as a synonym for '-text'. The '-' is optional:
throw Some::Error( flag => eSomethingBad );METHODS
- flag
-
set/get the error flag.
