Criterion

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 ResultSets 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.
