Class LaxDefaultNameClass

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.

Constructor Details

LaxDefaultNameClass

public LaxDefaultNameClass(NameClass _base)
Parameters:
_base - this name class accepts a name if
  1. it's in the 'base" name class and
  2. it's not one of those excluded names

Method Details

accepts

public boolean accepts(String namespaceURI,
                       String localName)
checks if this name class accepts given namespace:localName pair.
Overrides:
accepts in interface 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.

visit

public Object visit(NameClassVisitor visitor)
visitor pattern support
Overrides:
visit in interface NameClass
