Interface XMLValidationSchema
- All Known Subinterfaces:
DTDValidationSchema
public interface XMLValidationSchema
Defines the API that validator schema instances have to implement. Schema
objects are results of parsing of input that defines validation rules;
things like DTD files, W3c Schema input documents and so on. Schema
instances can not be directly used for validation; they are blueprints
for constructing such validator Objects. Because of this, they are
also guaranteed to be thread-safe and reusable. One way to think of this
is that schemas are actual validator factories instead of
XMLValidationSchemaFactory
instances.
One note about creation of validator instances: since the validation
may be invoked from wide variety of contexts (from parser, from serializer,
from processing pipeline etc), the validation context is abstracted
as ValidationContext
. Instances may make use of additional
knowledge about actual implementing classes if they can safely determine
the type runtime, but should gracefully handle the cases where
the context is created by a caller that is not part of the same
StAX implementation as the validator.
