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);
