Class Criterion

java.lang.Object

com.smartgwt.client.docs.serverds.Criterion

public class Criterion
extends java.lang.Object

An object representing a criterion to apply to a record.

This class is not meant to be created and used, it is actually documentation of settings allowed in a DataSource descriptor (.ds.xml file), for use with Smart GWT Pro Edition and above. See com.smartgwt.client.docs.serverds for how to use this documentation.

A criterion is part of the definition of an AdvancedCriteria object, which is used to filter records according to search criteria.

A criterion consists of an operator and typically a fieldName from a Record and a value to compare to. However some operators either don't require a value (eg, isNull) or act on other criteria rather than directly on a Record's fields (eg, the "and" and "or" logical operators).

A shortcut form is also allowed where only fieldName and value values are provided. In this case the operator is assumed to be "equals".
