- * Collection of "pseudo class" processors. Each processor is passed the current nodeset (array)\r
- * and the argument (if any) supplied in the selector.\r
+ * <p>Object hash of "pseudo class" filter functions which are used when filtering selections. Each function is passed\r
+ * two parameters:</p><div class="mdetail-params"><ul>\r
+ * <li><b>c</b> : Array<div class="sub-desc">An Array of DOM elements to filter.</div></li>\r
+ * <li><b>v</b> : String<div class="sub-desc">The argument (if any) supplied in the selector.</div></li>\r
+ * </ul></div>\r
+ * <p>A filter function returns an Array of DOM elements which conform to the pseudo class.</p>\r
+ * <p>In addition to the provided pseudo classes listed above such as <code>first-child</code> and <code>nth-child</code>,\r
+ * developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.</p>\r
+ * <p>For example, to filter <code><a></code> elements to only return links to <i>external</i> resources:</p>\r
+ * <code><pre>\r
+Ext.DomQuery.pseudos.external = function(c, v){\r
+ var r = [], ri = -1;\r
+ for(var i = 0, ci; ci = c[i]; i++){\r
+// Include in result set only if it's a link to an external resource\r
+ if(ci.hostname != location.hostname){\r
+ r[++ri] = ci;\r
+ }\r
+ }\r
+ return r;\r
+};</pre></code>\r
+ * Then external links could be gathered with the following statement:<code><pre>\r
+var externalLinks = Ext.select("a:external");\r
+</code></pre>\r
