DESCRIPTION

Clownfish::Err is the base class for exceptions in the Clownfish object hierarchy.

The Err module also provides access to a per-thread Err shared variable via set_error() and get_error(). It may be used to store an Err object temporarily, so that calling code may choose how to handle a particular error condition.

METHODS

cat_mess

$err->cat_mess($mess);

Concatenate the supplied argument onto the error message.

get_mess

my $string = $err->get_mess();

Return the error message.

INHERITANCE
