Modifier and Type	Method	Description
static boolean	checkComplexDerivationOk(XSComplexTypeDecl derived, org.apache.xerces.xs.XSTypeDefinition base, short block)	check whether complex type derived is valid derived from base, given a subset of {restriction, extension}.
static void	checkElementDeclsConsistent(XSComplexTypeDecl type, XSParticleDecl particle, SymbolHash elemDeclHash, SubstitutionGroupHandler sgHandler)
static boolean	checkSimpleDerivationOk(XSSimpleType derived, org.apache.xerces.xs.XSTypeDefinition base, short block)	check whether simple type derived is valid derived from base, given a subset of {restriction, extension}.
static boolean	checkTypeDerivationOk(org.apache.xerces.xs.XSTypeDefinition derived, org.apache.xerces.xs.XSTypeDefinition base, short block)	check whether derived is valid derived from base, given a subset of {restriction, extension}.B
static Object	ElementDefaultValidImmediate(org.apache.xerces.xs.XSTypeDefinition type, String value, ValidationContext context, ValidatedInfo vinfo)	check whether a value is a valid default for some type returns the compiled form of the value The parameter value could be either a String or a ValidatedInfo object
static void	findElemInTable(XSComplexTypeDecl type, XSElementDecl elem, SymbolHash elemDeclHash)
static void	fullSchemaChecking(XSGrammarBucket grammarBucket, SubstitutionGroupHandler SGHandler, CMBuilder cmBuilder, XMLErrorReporter errorReporter)	used to check the 3 constraints against each complex type (should be each model group): Unique Particle Attribution, Particle Derivation (Restriction), Element Declrations Consistent.
