Examples of org.jibx.schema.validation.ValidationContext

org.jibx.schema.validation.ValidationContext
Tracks the schema validation state. This includes order-dependent state information collected while walking the tree structure of a schema model. Collects all errors and warnings and maintains a summary of the severity of the problems found. For ease of use, this also wraps the schema name register with convenience methods for validation.
