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).

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 - . See String. 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:

. See String

setOperator

public void setOperator(OperatorId operator)

Operator this criterion applies.

Parameters:

operator - operator Default value is null

getOperator

public OperatorId getOperator()

Operator this criterion applies.

Returns:

OperatorId

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.

Parameters:

c - the passed criteria object
