  sk.uniba.euromath.document.schema.impl.tools.NameClassTools

public final class NameClassTools
extends Object

Serves as helper for SchemaImpl object. Introduces several useful methods, which works with com.sun.msv.grammar.NameClass classes. Intended to work only with org.w3c.dom.Document XML representation and com.sun.msv.grammar.NameClass expressions of Sun MSV package. Thread safe.

Method Detail

getAcceptedLocalnames

public Set<String> getAcceptedLocalnames(com.sun.msv.grammar.NameClass nc,
                                         boolean isElement)

Returns all local localnames that the nc accepts.

Parameters:

nc - NameClass that accepts elements names.

isElement - if given nameclass is element's nameclass.

Returns:

set of Strings, representing valid local localname parts. Namespaces can be get via the getLocalNamespace() function.

Throws:

IllegalStateException - if given nameclass accepts infinite number of local localnames.

acceptsForeign

public boolean acceptsForeign(com.sun.msv.grammar.NameClass nc,
                              boolean isElement)

Checks, whether this nameclass accepts some foreign qnames.

Parameters:

nc - nameclass to check.

isElement - whether this nameclass is element's nameclass or attribute's nameclass.

Returns:

true if nc accepts foreign qname.

acceptsFromNamespace

public static boolean acceptsFromNamespace(com.sun.msv.grammar.NameClass nc,
                                           String namespaceURI)

Checks, whether the nameclass accepts some qnames from given namespace.

Parameters:

nc - nameclass to check.

namespaceURI - the namespace

Returns:

true if nc accepts at least one qname from given namespace.

acceptsLocal

public boolean acceptsLocal(com.sun.msv.grammar.NameClass nc,
                            boolean isElement)

Checks, whether this nameclass accepts some local qnames.

Parameters:

nc - nameclass to check.

isElement - whether this nameclass is element's nameclass or attribute's nameclass.

Returns:

true if nc accepts local qname also.

getLocalNamespace

public String getLocalNamespace(boolean isElement)

Returns local namespace for this schema.

Parameters:

isElement - if return namespace for local element, or local attribute.

Returns:

namespaceURI for element, or "" for attribute.
