NAME

       Check::ISA - DWIM, correct checking of an object's class.

VERSION

       Version 0.09

SYNOPSIS

           use Check::ISA;

           if (obj($foo, "SomeClass")) {
               $foo->some_method;
           }

           # instead of one of these methods:
           UNIVERSAL::isa($foo, "SomeClass") # WRONG
           ref $obj eq "SomeClass"; # VERY WRONG
           $foo->isa("SomeClass") # May die
           local $@; eval { $foo->isa("SomeClass") } # too long

DESCRIPTION

       This module provides several functions to assist in testing whether a value is an object,
       and if so asking about its class.

FUNCTIONS

       obj $thing, [ $class ]
           This function tests if $thing is an object.

           If $class is provided, it also tests tests whether "$thing->isa($class)".

           $thing is considered an object if it's blessed or a "GLOB" with a valid "IO" slot (the
           "IO" slot contains a FileHandle object which is the actual invocant).  This
           corresponds directly to "gv_fetchmethod".

       obj_does $thing, [ $class_or_role ]
           Just like "obj" but uses "DOES" in UNIVERSAL instead of "isa" in UNIVERSAL.

           "DOES" in UNIVERSAL is just like "isa" except it's use is encouraged to query about an
           interface, as opposed to the object structure. If "DOES" is not overridden by the
           ebject, calling it is semantically identical to calling "isa".

           This is probably reccomended over "obj" for interoperability but can be slower on
           Perls before 5.10.

           Note that "DOES" in UNIVERSAL

       inv $thing, [ $class_or_role ]
           Just like "obj_does", but also returns true for classes.

           Note that this method is slower, but is supposed to return true for any value you can
           call methods on (class, object, filehandle, etc).

           Look into autobox if you would like to be able to call methods on all values.

       obj_can $thing, $method
       inv_can $thing, $method
           Checks if $thing is an object or class, and calls "can" on $thing if appropriate.
