Direct Known Subclasses:
JboCompareValidator, JboListValidator, JboMethodValidator, JboRangeValidator

public abstract class JboAbstractValidator
extends AbstractValidator

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

Constructor Detail

JboAbstractValidator

public JboAbstractValidator()
Method Detail

initialize

protected void initialize()

validateValue

public abstract boolean validateValue(java.lang.Object value)
Validates an object.

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.

validate

public void validate(JboValidatorContext evObj)

getNewValue

protected java.lang.Object getNewValue()

setNewValue

protected void setNewValue(java.lang.Object newValue)
                    throws java.lang.Exception
When the newValue is an Entity, get the attribute's value by using the getAttribute method on the entity. Otherwise, newValue should be a value to compare in this validator.

Parameters:
newValue - either the attribute's value or a value to use to compare in the validator.
Throws:
java.lang.Exception

setValidatingAttributeName

public void setValidatingAttributeName(java.lang.String name)
Overrides:
setValidatingAttributeName in class AbstractValidator

setValidatingAttribute

public void setValidatingAttribute(AttributeDef attr)
Sets the validating attribute.

Parameters:
attr - an attribute.

setValidatingAttribute

public void setValidatingAttribute(StructureDef beanInfo,
                                   java.lang.String str)
Sets the validating attribute by name.

This variant is used when the validator is attached to an entity, rather than to an attribute.

Parameters:
beanInfo - the entity containing the attribute.
str - an attribute name as a string.

getValidatingAttributeName

public java.lang.String getValidatingAttributeName()
Overrides:
getValidatingAttributeName in class AbstractValidator
