Class JboAbstractValidator

java.lang.Object

oracle.jbo.common.NamedObjectImpl

oracle.jbo.rules.AbstractValidator

oracle.jbo.rules.JboAbstractValidator

All Implemented Interfaces:

ComponentOperationsManager, DiffMergeable, DefPersistable, PersistentDefinition, JboValidatorHints, JboValidatorInterface, ValidatorConstants, VariableManagerOwner, VariableManagerOwnerBase

Direct Known Subclasses:

JboCompareValidator, JboExistsValidator, JboExpressionValidator, JboLengthValidator, JboListValidator, JboMandatoryAttrValHelper, JboMethodValidator, JboNonNullValidator, JboParamRequiredValidator, JboPrecisionScaleValidator, JboRangeValidator, JboRegExpValidator, JboRequiredValidator, JboUniqueKeyValidator, JboValidationBean, JboVCItemRequiredValidator

public abstract class JboAbstractValidator
extends AbstractValidator
implements JboValidatorHints, ComponentOperationsManager

The superclass for all pre-defined validators.

This class implements the basic functionality of storing the value of either an attribute to be validated, or the entity or application module reference on which validation is to be invoked. Subclasses must provide validateValue, which performs the actual validation test.

Since:

Jdeveloper 3.0
