|
||
<p>Values are strongly informational objects for which
|
||
identity is not significant, i.e. the focus is principally on
|
||
their state content and any behavior organized around
|
||
that. Another distinguishing feature of values is their
|
||
granularity: normally fine-grained objects representing simple
|
||
concepts in the system such as quantities.</p>
|
||
<p>As the emphasis of a value lies in its state not its
|
||
identity, values can be copied and typically assigned one to
|
||
another, requiring the explicit or implicit definition of a
|
||
public copy constructor and public assignment operator. Values
|
||
typically live within other scopes, i.e. within objects or
|
||
blocks, rather than on the heap. Values are therefore normally
|
||
passed around and manipulated directly as variables or through
|
||
references, but not as pointers that emphasize identity and
|
||
indirection.</p>
|
||
<p>The specific requirements on value types to be used in an
|
||
<code class="computeroutput"><a class="link" href="../boost/any.html" title="Class any">any</a></code>

||
