NAME

       UR::Object::Tag - Transitory attribute tags for a UR::Object at a given time.

SYNOPSIS

         if (my @attribs = grep { $_->type eq 'invalid' } $obj->attribs()) {
             print $obj->display_name . " has invalid attributes.  They are:\n";
             for my $atrib (@attribs) {
                 print join(",",$attrib->properties) . ":" . $attrib->desc . "\n";
             }
         }

         Project H_NHF00 has invalid attributes, they are:
         project_subdirectory : Directory does not exist.
         target, status : Target cannot be null for projects with an active status.

DESCRIPTION

       Objects of this class are created by create_attribs() on classes derived from UR::Object.
       They are retrieved by UR::Object->attribs().

INHERITANCE

       This class inherits from UR::ModuleBase.

OBJECT METHODS

       type
           A single-word description of the attribute which categorizes the attribute.  Common
           attribute types are:

           invalid
                 Set when the object has invalid properties and cannot be saved.

           changed
                 Set when the object is different than its "saved" version.

           hidden
                 Set when the object has properties which should not be shown.

           editable
                 Set when some part of the object is editable in the current context.

           warning
                 Set when a warning about the state of the object is in effect.

           match Set when a search which is in effect matches this object's property(s).

           comment
                 Set when this attribute is just an informational message.

       properties
           A list of properties to which the attribute applies.  This is null when the attribute
           applies to the whole object, but typically returns one property name.  Occasionally,
           it returns more than one property.  Very rarely (currently never), the property may be
           in the form of an arrayref like: [ class_name, id, property_name ], in which case the
           property may actually be that of another related object.

       desc
           A string of text giving detail to the attribute.

CLASS METHODS

       create
           Makes a new UR::Object::Tag.

       delete
           Throws one away.

       filter
           Sets/gets a filter to be applied to all attribute lists returned in the application.
           This gives the application developer final veto power over expressed attributes in the
           app.  In most cases, developers will write view components which use attributes, and
           will ignore them rather than plug-in at this low level to augment/mangle/supress.

           The filter will be given an object reference and a reference to an array of attributes
           which are tentatively to be delivered for the object.
