oracle.jbo.server.rules
Class JboBaseValidator

java.lang.Object
  extended by oracle.jbo.common.NamedObjectImpl
      extended by oracle.jbo.rules.AbstractValidator
          extended by oracle.jbo.server.rules.JboBaseValidator

All Implemented Interfaces:
ValidatorConstants, VariableManagerOwner, VariableManagerOwnerBase
Direct Known Subclasses:
JboCompareValidator, JboListValidator, JboMethodValidator, JboRangeValidator

public abstract class JboBaseValidator
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

Field Detail

mValidatingAttr

protected AttributeDefImpl mValidatingAttr

mValidatingAttrName

protected java.lang.String mValidatingAttrName

mBindingStyle

protected int mBindingStyle

Constructor Detail

JboBaseValidator

public JboBaseValidator()

Method Detail

initialize

protected void initialize()

extractValueToValidate

protected java.lang.Object extractValueToValidate(PropertyChangeEvent evObj)

vetoableChange

public void vetoableChange(PropertyChangeEvent evObj)
                    throws JboException
Invokes validateValue() on a value contained in a constrained property.

.

Parameters:
evObj - a PropertyChangeEvent containing a property to be validated.
Throws:
JboException - if validation fails, with CSMessageBundle error code EXC_VAL_ATTR_SET_FAILED.

raiseException

protected void raiseException(java.lang.Exception e,
                              PropertyChangeEvent evObj)

validateValue

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

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

setValidatingAttribute

public void setValidatingAttribute(AttributeDefImpl attr)
Sets the validating attribute.
Parameters:
attr - an attribute.

setValidatingAttribute

public void setValidatingAttribute(EntityDefImpl 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.

getBindingStyle

public int getBindingStyle()

setBindingStyle

public void setBindingStyle(int bindingStyle)

loadXMLContents

public void loadXMLContents(DefElement elem)
Overrides:
loadXMLContents in class AbstractValidator

resolve

public void resolve(ValidationManager owner,
                    StructureDef structDef,
                    PersistableDefObject defObj)
Overrides:
resolve in class AbstractValidator
