      public class Criteria
      extends DataClass

  Criteria for selecting only a matching set of records from a DataSource. Criteria can be applied on the client and server. Unless configured otherwise, criteria will generally be applied client-side by `ResultSet`s via `ResultSet.applyFilter`.

  Client- and server-side systems built into Smart GWT understand two criteria formats by default: simple key-value pairs (Criteria) or the `AdvancedCriteria` format.

  Use `DataSource.combineCriteria` to combine two Criteria objects (including Criteria and AdvancedCriteria) or `DataSource.convertCriteria` to convert simple Criteria to the AdvancedCriteria format.

  When sent to the Smart GWT server, the Java representation of the criteria is described `here`. When sent to other servers, the `operationBinding.dataProtocol` affects the format.
