:relfileprefix: ../../
:mrdocs:

This class implements a value‐semantic collection of unique attributes.

== Synopsis

Declared in `<ball_managedattributeset.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class ManagedAttributeSet;
----

== Description

(Note that an attribute is a compound entity that, as a whole, must be unique although individual parts need not be.) Additionally, the `evaluate` accessor can be used to determine if every attribute in the set is present in the specified attribute container list.
