NAME
       Declare::Constraints::Simple::Library::OO - OO Constraints

SYNOPSIS
	 # accept objects or classes
	 my $object_or_class = Or( IsObject, IsClass );

	 # valid on objects with all methods
	 my $proper_object = And( IsObject,
				  HasMethods( qw(foo bar) ));

	 # validate against date objects
	 my $is_date_object = IsA('DateTime');

DESCRIPTION
       This library contains the constraints for validating parameters in an
       object oriented manner.

CONSTRAINTS
   HasMethods(@methods)
       Returns true if the value is an object or class that "can" all the
       specified @methods.

       The stack or path part of "HasMethods" looks like "HasMethods[$method]"
       where $method is the first found missing method.

   IsA(@classes)
       Is true if the passed object or class is a subclass of one of the
       classes mentioned in @classes.

   IsClass()
       Valid if value is a loaded class.

   IsObject()
       True if the value is blessed.
