public class ENTITYDatatypeValidator

extends AbstractDatatypeValidator

ENTITYDatatypeValidator implements the DatattypeValidator interface. This validator embodies the ENTITY attribute type from XML1.0 recommendation. The Value space of ENTITY is the set of all strings that match the NCName production and have been declared as an unparsed entity in a document type definition. The Lexical space of Entity is the set of all strings that match the NCName production. The value space of ENTITY is scoped to a specific instance document. Some caveats: Because of the Xerces Architecture, where all symbols are stored in a StringPool and Strings are referenced by int then this datatype needs to know about StringPool. The first time that this datatype is invoked we pass a message containing 2 references needed by this validator: - a reference to the DefaultEntityHandler used by the XMLValidator. - a reference to the StringPool. This validator extends also the XML1.0 validation provided in DTD by providing "only on Schemas" facet validation. This validator also embodies the Derived datatype ENTITIES which is an ENTITY derived by list. These validators can be supplied by the application writer and may be useful as standalone code as well as plugins to the validator architecture.

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 Detail

validate

public java.lang.Object validate(java.lang.String content,

                          throws InvalidDatatypeValueException

Checks that "content" string is valid datatype. If invalid a Datatype validation exception is thrown.

Parameters:

content - A string containing the content to be validated

derivedBylist - Flag which is true when type is derived by list otherwise it it is derived by extension.

Throws:

throws - InvalidDatatypeException if the content is invalid according to the rules for the validators

InvalidDatatypeValueException -

Overrides:

validate in class AbstractDatatypeValidator
