#include <DbXml.hpp> virtual XmlResolver::~XmlResolver()
Provides an unimplemented base class that is used for file resolution
policy. Implementations of this class are used for URI resolution,
or for public and system ids resolution.
XmlResolver implementations are identified for
use using XmlManager::registerResolver.
The XmlResolver class allows applications to
provide named access to application-specific objects, such as
documents, collections of documents, DTDs, and XML schema. Berkeley
DB XML can resolve references to names within a container, or a file
system; applications can create XmlResolver
instances that can resolve entities in other locations.
For an example of an XmlResolver
implementation, see the Berkeley DB XML distribution file
test/cpp/util/TestResolver.cpp.
If an application uses multiple threads, custom implementations of
XmlResolver must be free threaded, and allow
multiple, simultaneous calls for resolution.
