Represents a filter that can be applied to a MixedCollection. Can either simply +filter on a property/value pair or pass in a filter function with custom logic. Filters are always used in the context +of MixedCollections, though Stores frequently create them when filtering and searching on their +records. Example usage:

+ + +
//set up a fictional MixedCollection containing a few people to filter on
+var allNames = new Ext.util.MixedCollection();
+allNames.addAll([
+    {id: 1, name: 'Ed',    age: 25},
+    {id: 2, name: 'Jamie', age: 37},
+    {id: 3, name: 'Abe',   age: 32},
+    {id: 4, name: 'Aaron', age: 26},
+    {id: 5, name: 'David', age: 32}
+]);
+
+var ageFilter = new Ext.util.Filter({
+    property: 'age',
+    value   : 32
+});
+
+var longNameFilter = new Ext.util.Filter({
+    filterFn: function(item) {
+        return item.name.length > 4;
+    }
+});
+
+//a new MixedCollection with the 3 names longer than 4 characters
+var longNames = allNames.filter(longNameFilter);
+
+//a new MixedCollection with the 2 people of age 24:
+var youngFolk = allNames.filter(ageFilter);
