<div class="textblock"><p>Represents a shared variant value. </p>
<p>A <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> object contains a reference to a var object, and can get and set its value. Listeners can be attached to be told when the value is changed.</p>
<p>The <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> class is a wrapper around a shared, reference-counted underlying data object - this means that multiple <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> objects can all refer to the same piece of data, allowing all of them to be notified when any of them changes it.</p>
<p>When you create a <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> with its default constructor, it acts as a wrapper around a simple var object, but by creating a <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> that refers to a custom subclass of <a class="el" href="classValue_1_1ValueSource.html" title="Used internally by the Value class as the base class for its shared value objects. ">ValueSource</a>, you can map the <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> onto any kind of underlying data.</p>
<p>Important note! The <a class="el" href="classValue.html" title="Represents a shared variant value. ">Value</a> class is not thread-safe! If you're accessing one from multiple threads, then you'll need to use your own synchronisation around any code that accesses it. </p>
