Perl - is object instance of class? -

is there way check whether object instance of class? object instance of class if has been blessed class:

package example;  sub new {     $self = {};     bless($self, shift);     return $self; }  ############  use example; $exp = example->new(); # $exp 'instance' of example # instanceof($exp, example) return 1 

the blessed() subroutine scalar::util returns name of class object belongs to.

say blessed $exp; # prints "example" 

for test, use like:

if (blessed $exp eq 'example') { ...} 

if subclassing issue, use isa() instead.

if ($exp->isa('example')} { ... } 

but throws error if $exp isn't object, protect call calling blessed() first.

if (blessed($exp) , $exp->isa('example')) { ... } 

isa() method on universal class , every class subclass of universal, every object has isa() method.
