public abstract class Schema extends Object
Immutable in-memory representation of grammar.This object represents a set of constraints that can be checked/ enforced against an XML document.
A
Schemaobject is thread safe and applications are encouraged to share it across many parsers in many threads.A
Schemaobject 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 sameSchema, it must always produce the same result.A
Schemaobject is usually created fromSchemaFactory.Two kinds of validators can be created from a
Schemaobject. One isValidator, which provides highly-level validation operations that cover typical use cases. The other isValidatorHandler, 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).

Method Detail
newValidator
public abstract Validator newValidator()
Creates a newValidatorfor thisSchema.A validator enforces/checks the set of constraints this object represents.
Implementors should assure that the properties set on the
SchemaFactorythat created thisSchemaare also set on theValidatorconstructed.- Returns:
- Always return a non-null valid object.
newValidatorHandler
public abstract ValidatorHandler newValidatorHandler()
Creates a newValidatorHandlerfor thisSchema.Implementors should assure that the properties set on the
SchemaFactorythat created thisSchemaare also set on theValidatorHandlerconstructed.- Returns:
- Always return a non-null valid object.
