public class DatatypeValidatorFactoryImpl

extends java.lang.Object

implements DatatypeValidatorFactory

This class implements a factory of datatype validators. Internally the DatatypeValidators are kept in three registries:
(i) DTDRegistry - stores DTD datatype validators SchemaRegistry - stores Schema datatype validators UserDefinedRegistry - stores Schema user defined datatypes.
The above registries will be initialized on demand (for XML document with a DTD, only DTDRegistry will be initialized).
Note: Between multiple parse() calls, only _user_defined_ registry will be reset. DTD registry and schema registry are initialized only once and are kept for the *life-time* of the parser .
This implementation uses a Hahtable as a registry table but future implementation should use a lighter object, maybe a Map class ( not use a derived Map class because of JDK 1.1.8 no supporting Map).

As the Parser parses an instance document it knows if validation needs to be checked. If no validation is necessary we should not instantiate a DatatypeValidatorFactoryImpl.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Method Summary

DatatypeValidator	createDatatypeValidator(java.lang.String typeName, DatatypeValidator base, java.util.Hashtable facets, boolean list)
DatatypeValidator	createDatatypeValidator(java.lang.String typeName, java.util.Vector validators)
void	expandRegistryToFullSchemaSet() Initializes fSchemaDatatypeRegistry with schema primitive and derived datatypes.
DatatypeValidator	getDatatypeValidator(java.lang.String type) Searches different datatype registries depending on validation mode (schema or dtd)
void	initializeDTDRegistry() Initializes fDTDRegistry with (9) DTD related datatypes .
void	resetRegistry() An optimization option that we should write in the future is to separate the static list of Datatype Validators from the dynamic part where anonymous, and user derived datatype are kept, then when we resetRegistry only the dynamic part of the registry should be cleared.

Method Detail

initializeDTDRegistry

public void initializeDTDRegistry()

Initializes fDTDRegistry with (9) DTD related datatypes .

expandRegistryToFullSchemaSet

public void expandRegistryToFullSchemaSet()

Initializes fSchemaDatatypeRegistry with schema primitive and derived datatypes. See W3C Schema Datatype REC. If DTD registry is not initialized yet, this method will initialize it as well.

resetRegistry

public void resetRegistry()

An optimization option that we should write in the future is to separate the static list of Datatype Validators from the dynamic part where anonymous, and user derived datatype are kept, then when we resetRegistry only the dynamic part of the registry should be cleared. So we don't end up clearing the static part of the table over and over every time that we do a parse cycle.

createDatatypeValidator

public DatatypeValidator createDatatypeValidator(java.lang.String typeName,
                                                 DatatypeValidator base,
                                                 java.util.Hashtable facets,
                                                 boolean list)
                                          throws InvalidDatatypeFacetException

Specified by:

                                                 java.util.Vector validators)
