<p>This class acts as a typed wrapper around a property inside a <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a>. </p>
<p>A <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a> provides an easy way to read and write a <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a> property with a chosen type. So for example a CachedValue<int> allows you to read or write the property as an int, and a CachedValue<String> lets you work with it as a <a class="el" href="classString.html" title="The JUCE String class! ">String</a>.</p>
<p>It also allows efficient access to the value, by caching a copy of it in the type that is being used.</p>
<p>You can give the <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a> an optional <a class="el" href="classUndoManager.html" title="Manages a list of undo/redo commands. ">UndoManager</a> which it will use when writing to the underlying <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a>.</p>
<p>If the property inside the <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a> is missing, the <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a> will automatically return an optional default value, which can be specified when initialising the <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a>.</p>
<p>To create one, you can either use the constructor to attach the <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a> to a <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a>, or can create an uninitialised <a class="el" href="classCachedValue.html" title="This class acts as a typed wrapper around a property inside a ValueTree. ">CachedValue</a> with its default constructor and then attach it later with the <a class="el" href="classCachedValue.html#a22c029d41ad7c38c01d91e8b77bdcae6" title="Makes the CachedValue refer to the specified property inside the given ValueTree. ...">referTo()</a> methods.</p>
<p>Common types like <a class="el" href="classString.html" title="The JUCE String class! ">String</a>, int, double which can be easily converted to a var should work out-of-the-box, but if you want to use more complex custom types, you may need to implement some template specialisations of <a class="el" href="structVariantConverter.html" title="This template-overloaded class can be used to convert between var and custom types. ">VariantConverter</a> which this class uses to convert between the type and the <a class="el" href="classValueTree.html" title="A powerful tree structure that can be used to hold free-form data, and which can handle its own undo ...">ValueTree</a>'s internal var. </p>
