Class ChainValidatorMetaDataReader

java.lang.Object

org.boon.validation.readers.ChainValidatorMetaDataReader

All Implemented Interfaces:

ValidatorMetaDataReader

public class ChainValidatorMetaDataReader
extends java.lang.Object
implements ValidatorMetaDataReader

This class allows you to chain validator readers. This way you can read validation data from more than one source.

For example, you could read validation meta data from properties files, and annotation.

The last one configured in the chain wins if you have the same type.

You can have a required validation rule in a properties file and a regex in an annotation for the same property and both applied. Thus, it also merges as long as they are different types.
