Class LaxDefaultNameClass

java.lang.Object
com.sun.msv.grammar.NameClass
com.sun.msv.grammar.xmlschema.LaxDefaultNameClass
All Implemented Interfaces:
Serializable
public class LaxDefaultNameClass extends NameClass
Special name class implementation used for the wild card of the "lax" mode.

In "lax" mode, we need a name class that matches all undefined names. Although it is possible to use DifferenceNameClass for this purpose, it is not a cost-efficient way because typically it becomes very large. (If there are twenty element declarations, we'll need twenty DifferenceNameClass to exclude all defined names).

This name class uses a Set to hold multiple names. If a name is contained in that set, it'll be rejected. If a name is not contained, it'll be accepted.

Special care is taken to make this NC as seamless as possible. When the visit method is called, the equivalent name class is constructed internally and the visitor will visit that name class. In this way, the visitors won't notice the existance of this "special" name class.

    • LaxDefaultNameClass

      public LaxDefaultNameClass(NameClass _base)
      Parameters:

      1. it's in the 'base" name class and
      2. it's not one of those excluded names

  • Method Details

    • visit

      public Object visit(NameClassVisitor visitor)
      Description copied from class: NameClass
      visitor pattern support
      Specified by:
      visit in class NameClass

    • accepts

      public boolean accepts(String namespaceURI, String localName)
      Description copied from class: NameClass
      checks if this name class accepts given namespace:localName pair.
      Specified by:
      accepts in class NameClass
      Parameters:
      namespaceURI - namespace URI to be tested. If this value equals to NAMESPACE_WILDCARD, implementation must assume that valid namespace is specified. this twist will be used for error diagnosis.
      localName - local part to be tested. As with namespaceURI, LOCALNAME_WILDCARD will acts as a wild card.
      Returns:
      true if the pair is accepted, false otherwise.

    • addName

      public void addName(String namespaceURI, String localName)
      add a name so that this name will be rejected by the accepts method.
