Class Operator

java.lang.Object

com.smartgwt.client.docs.serverds.Operator

public class Operator
extends java.lang.Object

Specification of an operator for use in filtering, for example "equals".

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.

Use with DataSource.addSearchOperator() to define custom filtering behaviors for client-side filtering.

Field Detail

symbol

public java.lang.String symbol

The text use when using this operator as an expression in a FormItem.

Default value is null

hidden

public boolean hidden

Whether this operator should be offered to users by default in interfaces such as the FilterBuilder.

Setting hidden:true means the operator can be used in a programmatic search, for example, by calling ResultSet.setCriteria(), but does not appear in the UI.

Default value is false

fieldTypes

public FieldType[] fieldTypes

List of types that this Operator is valid for.

If omitted, the operator is assumed to be valid for all FieldTypes unless a list of FieldTypes is passed to DataSource.addSearchOperator().

Default value is null

titleProperty

public java.lang.String titleProperty

Name of a property on the Operators class that provides the title for this operator.

Default value is null

requiresServer

public boolean requiresServer

Whether this operator needs to be executed on the server side.

This implies that if a Criterion using this operator is either introduced into criteria or is changed, the server will need to be contacted to perform filtering.

Default value is false

ID

public OperatorId ID

Unique id for an operator, which appears within AdvancedCriteria as the Operator property.

A list of built-in identifiers is here.

Default value is null

title

public java.lang.String title

User-visible title for this operator, such as "doesn't contain".

To simplify internationalization by separating titles from operator code, you can use specify titleProperty instead of this property.

Default value is null

valueType

public OperatorValueType valueType

Indicates the kind of value expected in a Criterion that uses this operator. OperatorValueType lists possibilities.

The default of null is equivalent to "fieldType", indicating that Criterion.value is expected to contain a value of the same type as the field indicated by Criterion.fieldName.

Default value is null

editorType

public FormItem editorType

For an operator with valueType:"custom", indicates what kind of FormItem to use to provide a user interface for creating a valid Criterion. The default of null means an ordinary TextItem is fine.

Default value is null
