+         * 
Object hash of "pseudo class" filter functions which are used when filtering selections. Each function is passed
+         * two parameters:
    
+         * 
  • c : Array
    An Array of DOM elements to filter.
    • 
+         * 
  • v : String
    The argument (if any) supplied in the selector.
    • 
+         * 

+         * 
A filter function returns an Array of DOM elements which conform to the pseudo class.

+         * 
In addition to the provided pseudo classes listed above such as first-child and nth-child,
+         * developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.

+         * 
For example, to filter <a> elements to only return links to external resources:

+         * 
+Ext.DomQuery.pseudos.external = function(c, v){
+    var r = [], ri = -1;
+    for(var i = 0, ci; ci = c[i]; i++){
+//      Include in result set only if it's a link to an external resource
+        if(ci.hostname != location.hostname){
+            r[++ri] = ci;
+        }
+    }
+    return r;
+};

+         * Then external links could be gathered with the following statement:
+var externalLinks = Ext.select("a:external");
+
