Class ValidationXMLReader

java.lang.Object

org.eclipse.persistence.jaxb.ValidationXMLReader

All Implemented Interfaces:

Callable<Map<Class<?>,Boolean>>

public class ValidationXMLReader
extends Object
implements Callable<Map<Class<?>,Boolean>>

Detects external Bean Validation configuration.

Strategy:
1. Parse validation.xml, looking for a constraints-file reference.
2. For each reference, if file is found, parses the constraints file and puts all classes declared under <bean class="clazz"> into BeanValidationHelper.constraintsOnClasses with value Boolean.TRUE.

This class contains resources-burdening instance fields (e.g. SAXParser) and as such was designed to be instantiated once (make the instance BOUNDED) and have call() method called on that instance once.

Not suitable for singleton (memory burden). The method #parse() will be invoked only once per class load of this class. After that the instance and all its fields should be made collectible by GC.
