All Implemented Interfaces:

IDContextProvider2, IVerifier, org.iso_relax.verifier.VerifierHandler, org.relaxng.datatype.ValidationContext, ContentHandler, DTDHandler

public class IDConstraintChecker
extends Verifier

Verifier with XML Schema-related enforcement.

This class can be used in the same way as Verifier. This class also checks XML Schema's identity constraint.

Field Details

grammar

protected final XMLSchemaGrammar grammar

the grammar object against which we are validating.

matchers

protected final Vector matchers

active mathcers.

keyValues

private final Map keyValues

a map from SelectorMatcher to set of KeyValues. One SelectorMatcher correponds to one scope of the identity constraint.

referenceScope

private final Map referenceScope

a map from keyref SelectorMatcher to key/unique SelectorMatcher. Given a keyref scope, this map stores which key scope should it refer to.

activeScopes

private final Map activeScopes

a map from IdentityConstraint to a LightStack of SelectorMatcher. Each stack top keeps the currently active scope for the given IdentityConstraint.
