public class Criterion
extends Criteria

An object representing a criterion to apply to a record.

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".

Method Detail

getOrCreateRef

public static Criterion getOrCreateRef(JavaScriptObject jsObj)

setCriteria

public void setCriteria(Criterion... criteria)

For a criterion with an operator that acts on other criteria (eg "and", "or"), a list of sub-criteria that are grouped together by the operator.

Parameters:

criteria - Default value is null

getCriteria

public Criterion[] getCriteria()

For a criterion with an operator that acts on other criteria (eg "and", "or"), a list of sub-criteria that are grouped together by the operator.

Returns:

Criterion...

setFieldName

public void setFieldName(java.lang.String fieldName)

Name of the field in each Record that this criterion applies to. Not applicable for a criterion with sub-criteria. Can be specified as a dataPath to allow matching nested objects. Use '/' as delimiters for dataPath. See dataPath for more information.

Parameters:

fieldName - Default value is null

getFieldName

public java.lang.String getFieldName()

Name of the field in each Record that this criterion applies to. Not applicable for a criterion with sub-criteria. Can be specified as a dataPath to allow matching nested objects. Use '/' as delimiters for dataPath. See dataPath for more information.

Returns:

String

setOperator

Parameters:

operator - Default value is null

getOperator

public OperatorId getOperator()

Operator this criterion applies.

Returns:

OperatorId

instanceOf

public static final boolean instanceOf(java.lang.Object object)

addCriteria

public void addCriteria(Criterion c)

Adds a new criteria.

If the present criteria operation is "and", the new criteria is appended to the criteria list.

Otherwise, the existing criteria is replaced with an "and" criteria, with two sub-criteria: the existing criteria, and the passed criteria.

Note that if the existing criteria was empty (as would happen if new AdvancedCriteria() were called with no arguments), an "and" operator will still be introduced, but the passed criteria will be the only sub-criteria.

To add an additional Criterion when using the "or" operator, use appendToCriterionList(com.smartgwt.client.data.Criterion).

Parameters:

c - the passed criteria object

addCriteria

public void addCriteria(Criteria c)

Adds a new criteria. If the passed criteria is a simple Criteria or Criterion, it will turn into AdvancedCriteria, and will be added to the existent criteria.

Overrides:

addCriteria in class Criteria

Parameters:

c - the passed criteria object

addCriteria

public void addCriteria(java.lang.String field,
               java.lang.String value)
