Class DefaultSchemaBindingValidator

java.lang.Object

org.jboss.xb.util.AbstractSchemaBindingValidator

org.jboss.xb.util.DefaultSchemaBindingValidator

All Implemented Interfaces:

SchemaBindingValidator

public class DefaultSchemaBindingValidator
extends AbstractSchemaBindingValidator

This class is used to check consistency between SchemaBinding instances and their corresponding XSD schemas. It can be configured to exclude (or include) validation of certain namespaces (i.e. types, elements and model groups from certain namespaces). By default, namespace "http://www.w3.org/2001/XMLSchema" is excluded. Also specific types identified by their QName can be excluded or included from validation. Simple XSD types are validated only if present in SchemaBinding. The reason for that is many simple types are bound/represented in Java model by java.lang.String which when building SchemaBinding is bound to xsd:string. Current implementation does not ensures complete consistency but only the basics such as existence of type definitions, element declarations, element ordering in groups and possible occurences of particles. When an inconsistency is found handleError(String msg) is called. The default implementation of which throws IllegalStateException. Subclasses can override this method to report errors differently. Sometimes the error itself may not be informative enough to e.g. identify the location of the inconsistency in the schema. In this case logging should be enabled. Default logger is an instance of org.jboss.logging.Logger with category org.jboss.xb.util.SchemaBindingValidator. All the messages are logged from method log(String msg) which subclasses can override.

handleError

protected void handleError(String msg)

This an error handler method. Default implementation throws IllegalStateException with the message passed in as the argument.

Overrides:

handleError in class AbstractSchemaBindingValidator

Parameters:

msg - the error message

log

protected void log(String msg)

This method is supposed to log a message. Default implementation uses trace logging.

Overrides:

log in class AbstractSchemaBindingValidator

Parameters:

msg - the message to log.
