    "description": "Provides the sorting information required to establish a sort on a field or property in a collection view.  The SortField class is meant to be used with the Sort class.  Typically the sort is defined for collections of complex items, that is items in which the sort is performed on properties of those objects. As in the following example:  <pre><code>\\n var col:ICollectionView = new ArrayCollection();\\n col.addItem({first:&quot;Anders&quot;, last:&quot;Dickerson&quot;});\\n var sort:Sort = new Sort();\\n sort.fields = [new SortField(&quot;first&quot;, true)];\\n col.sort = sort;\\n </code></pre>  There are situations in which the collection contains simple items, like <code>String</code>, <code>Date</code>, <code>Boolean</code>, etc. In this case, sorting should be applied to the simple type directly. When constructing a sort for this situation only a single sort field is required and should not have a <code>name</code> specified. For example:  <pre><code>\\n var col:ICollectionView = new ArrayCollection();\\n col.addItem(&quot;California&quot;);\\n col.addItem(&quot;Arizona&quot;);\\n var sort:Sort = new Sort();\\n sort.fields = [new SortField(null, true)];\\n col.sort = sort;\\n </code></pre>  <p>By default the comparison provided by the SortField class does not provide correct language specific sorting for strings.  For this type of sorting please see the <code>spark.collections.Sort</code> and <code>spark.collections.SortField</code> classes.</p>  Note: to prevent problems like <a href=&quot;https://issues.apache.org/jira/browse/FLEX-34853&quot;>FLEX-34853</a> it is recommended to use SortField instances as immutable objects (by not changing their state).   <p>The <code>&lt;mx:SortField&gt;</code> tag has the following attributes:</p>  <pre>\\n &lt;mx:SortField\\n <b>Properties</b>\\n caseInsensitive=&quot;false&quot;\\n compareFunction=&quot;<em>Internal compare function</em>&quot;\\n descending=&quot;false&quot;\\n name=&quot;null&quot;\\n numeric=&quot;null&quot;\\n /&gt;\\n </pre>",
