Template::Exception module defines an object class for
representing exceptions within the template processing life cycle.
Exceptions can be raised by modules within the Template Toolkit, or can
be generated and returned by user code bound to template variables.
Exceptions can be raised in a template using the
[% THROW user.login 'no user id: please login' %]
$context->throw('user.passwd', 'Incorrect Password'); $context->throw('Incorrect Password'); # type 'undef'
or from Perl code by calling
die() with a
die (Template::Exception->new('user.denied', 'Invalid User ID'));
or by simply calling
die() with an error string. This is
automagically caught and converted to an exception of
undef' type (that's the literal string '
rather than Perl's undefined value) which can then be handled in the
die "I'm sorry Dave, I can't do that";
Each exception is defined by its type and a information component (e.g.
error message). The type can be any identifying string and may contain
dotted components (e.g. '
foo.bar.baz'). Exception types are considered to be
hierarchical such that '
foo.bar' would be a specific type of
the more general '
