oracle.jbo.server.rules.JboBaseValidator
public abstract class JboBaseValidator
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.

evObj
- a PropertyChangeEvent
containing a property
to be validated.
JboException
- if validation fails, with CSMessageBundle

.protected void raiseException(java.lang.Exception e, PropertyChangeEvent evObj)
public abstract boolean validateValue(java.lang.Object value) throws java.lang.Exception
Subclasses must implement this method.
value
- the object to be validated.
true
if the object is valid.
java.lang.Exception
- if validation cannot be performed.protected void setNewValue(java.lang.Object newValue) throws java.lang.Exception
newValue
- either the attribute's value or a value to use to compare
in the validator.

attr
- an attribute.public void setValidatingAttribute(EntityDefImpl beanInfo, java.lang.String str)
This variant is used when the validator is attached to an entity, rather than to an attribute.

- the entity containing the attribute.str
- an attribute name as a string.public int getBindingStyle()
