Class SimpleValidator<B>

java.lang.Object
  net.sf.doolin.gui.validation.AbstractValidator<B>
      net.sf.doolin.gui.validation.SimpleValidator<B>

Type Parameters:

B - Type of object for the view

All Implemented Interfaces:

GUIValidator<B>

public class SimpleValidator<B>
extends AbstractValidator<B>

Validator based on textual declarations.

Each validation has the following format:

 <validation> := <context>=<validators>
 
 <context> := <key>:<property>[:<name>]
 <validators> := Comma-separated list of <validator>
 

where:

• key: Key that identifies the field in error, usually mapped to the field name
• property: Path to the property to test on the model
• name: String key to the name of the field (defaults to the field name)
• validator: key used to identify an ObjectValidator for the validation (see below)

validator keys are used to identify ObjectValidator instances. Predefined ones are:

• notNull
• notBlank

It is possible to declare new keys using the setObjectValidators(Map) method or the objectValidators property.
