  edu.ksi.virtualclassroom.mappers.jaxb.xmlwrapper.impl.runtime.ValidationContext

class ValidationContext

extends java.lang.Object

Maintains information that needs to be stored across * validations of multiple objects. * * Specifically, this object is responsible for: * *

*
1. detecting a cycle in a content tree by keeping track of * objects that were validated. * *
2. keeping an instance of NamespaceContextImpl, which is * shared by all MSVValidators. * *
3. keeping a reference to ValidationErrorHandler. * MSVValidators should use this error handler to report any error. *
