public interface SchemaComponent
extends Serializable

This is a marker interface that represents any "schema component" as defined in the XML Schema specification. This may be a user-defined schema component or a built-in schema component. Since all built-in schema components are types, every SchemaComponent in practice is either a UserSchemaComponent or a SchemaType or both.

Method Detail

getValidationStatus

int getValidationStatus()
Get the validation status of this component.

Returns:
one of the values UNVALIDATED, VALIDATING, VALIDATED, INVALID, INCOMPLETE

getRedefinitionLevel

int getRedefinitionLevel()
Get the redefinition level. This is zero for a component that has not been redefined; for a redefinition of a level-0 component, it is 1; for a redefinition of a level-N component, it is N+1. This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.

Returns:
the redefinition level
