Class AnnotationValidatorMetaDataReader

java.lang.Object

org.boon.validation.readers.AnnotationValidatorMetaDataReader

All Implemented Interfaces:

Serializable, ValidatorMetaDataReader

public class AnnotationValidatorMetaDataReader
extends Object
implements ValidatorMetaDataReader, Serializable

AnnotationValidatorMetaDataReader reads validation meta-data from annotations.

This class reads a annotation as follows: You pass in the base package of the annotations it defaults to "org.boon.annotations.validation". It then takes the name of the ValidatorMetaData and capitalizes the first letter. Thus if you pass the package "com.my.company.annotations", and ValidatorMetaData.name = "required", then it will look for an annotation called com.my.company.annotations.Required. The idea behind this is that you can use annotation without polluting your model classes with Boon annotations.

The parent class that owns the annotation should have annotation as follows:
