Class JboAbstractValidator

java.lang.Object
oracle.jbo.common.NamedObjectImpl
oracle.jbo.rules.AbstractValidator
oracle.jbo.rules.JboAbstractValidator

All Implemented Interfaces:

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

Direct Known Subclasses:

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

public abstract class JboAbstractValidator

extends AbstractValidator

implements JboValidatorHints

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

protected void setInitialized()

initialize

protected void initialize(JboValidatorContext evObj)

getTriggeringAttributeDefs

public AttributeDef[] getTriggeringAttributeDefs()

Description copied from interface: JboValidatorHints

Returns an array of attribute defs for those attributes whose change in value, should trigger this validation rule to execute.

Specified by:

getTriggeringAttributeDefs in interface JboValidatorHints

Overrides:

getTriggeringAttributeDefs in class AbstractValidator

getErrorMsgId

public java.lang.String getErrorMsgId()

Overrides:

getErrorMsgId in class AbstractValidator

validateValue

public abstract boolean validateValue(java.lang.Object value)

Validates a value.

Subclasses must implement this method.

Parameters:

value - the object to be validated.

Returns:

true if the object is valid.

Throws:

java.lang.Exception - if validation cannot be performed.

validateValueWithContext

public boolean validateValueWithContext(JboValidatorContext evObj,
                                        java.lang.Object value)

Called internally by the framework with validation OnCondition is true or there is no validation OnCondition. This method should not be directly invoked in applications.

validate

public void validate(JboValidatorContext evObj)

Description copied from interface: JboValidatorInterface

Tests the validity of the object/value as described in the validator context.

Specified by:

validate in interface JboValidatorInterface

Parameters:

evObj - the validator context
