Immutable in-memory representation of grammar.
This object represents a set of constraints that can be checked/ enforced against an XML document.
A Schema
object is thread safe and applications are
encouraged to share it across many parsers in many threads.
A Schema
object is immutable in the sense that it shouldn't
change the set of constraints once it is created. In other words,
if an application validates the same document twice against the same
Schema
, it must always produce the same result.
A Schema
object is usually created from SchemaFactory
.
Two kinds of validators can be created from a Schema
object.
One is Validator
, which provides highly-level validation
operations that cover typical use cases. The other is
ValidatorHandler
, which works on top of SAX for better
modularity.
This specification does not refine
the Object.equals(java.lang.Object)
method.
In other words, if you parse the same schema twice, you may
still get !schemaA.equals(schemaB)
.
