Schema

public abstract class Schema
extends Object

java.lang.Object
↳	javax.xml.validation.Schema

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).

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.

`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
