Class Validator

  +--org.chwf.filter.Validator

Direct Known Subclasses:

GenericValidator

public abstract class Validator

extends java.lang.Object

The Validator class is the abstract superclass of all validators. Validators serve as an abstraction layer supporting common validation logic. You can define custom Validator classes for a given JavaBean by defining a new class that has the same name as the JavaBean, with "Validator" added. If no custom validators are defined, Chrysalis will use the GenericValidator instead.

Validator

protected Validator(java.lang.Class beanClass)

Constructor to specify the class of validated bean. This constructor is called by subclasses: super(beanClass);

Parameters:

beanClass - The class of the validated bean.

Method Detail

findValidator

public static Validator findValidator(java.lang.Object object)
                               throws InitializationException

Find the validator for a given object.

Parameters:

object - The object being validated.

Returns:

The validator.

Throws:

InitializationException - If it cannot be initialized.

findValidator

public static Validator findValidator(java.lang.Class beanClass)
                               throws InitializationException

Find the validator for a given class.

Parameters:

beanClass - The class of the validated bean.

Returns:

The validator.

Throws:

InitializationException - If it cannot be initialized.

findValidator

public static Validator findValidator(java.lang.String className)
                               throws InitializationException

Find the validator for the specified class name. This method first searches for the validator class beanClass + "Validator". If it cannot create this object it creates a GenericValidator for the bean class using reflection.

Parameters:

className - This must be the fully qualified name of the class.

Returns:

The validator.

Throws:

InitializationException - If it cannot be initialized.

getBeanClass

public java.lang.Class getBeanClass()

The validated class.

Returns:

The validated class.
