Template::Exception - phpMan

NAME
    Template::Exception - Exception handling class module

SYNOPSIS
        use Template::Exception;

        my $exception = Template::Exception->new($type, $info);
        $type = $exception->type;
        $info = $exception->info;
        ($type, $info) = $exception->type_info;

        print $exception->as_string();

        $handler = $exception->select_handler(\@candidates);

DESCRIPTION
    The "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" directive,

        [% THROW user.login 'no user id: please login' %]

    or by calling the throw() method on the current Template::Context
    object,

        $context->throw('user.passwd', 'Incorrect Password');
        $context->throw('Incorrect Password');    # type 'undef'

    or from Perl code by calling "die()" with a "Template::Exception"
    object,

        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 '"undef"' rather than Perl's undefined value) which can
    then be handled in the usual way.

        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"', '"foo.bar"', '"foo.bar.baz"').
    Exception types are considered to be hierarchical such that '"foo.bar"'
    would be a specific type of the more general '"foo"' type.

METHODS
  type()
    Returns the exception type.

  info()
    Returns the exception information.
