DeclarativeQueryManager is a derived interface of
QueryManager that provides the ability to search
the registry using queries expressed directly in one of the query
languages that it supports, rather than using a query generated as a
result of calling one of the methods of the
QueryManager or
BusinessQueryManager interfaces. A
DeclarativeQueryManager can be obtained from the
RegistryService object of a level 1 JAXR provider.
The query languages that a DeclarativeQueryManager
supports are implementation-dependent and might include SQL-92, the
ebXML filter query language, or XQuery. The createQuery(
) method returns a Query object that
encapsulates a specified query expressed in a given query language.
An InvalidRequestType exception is thrown if the
JAXR provider does not support the requested query language or if the
query string appears to be invalid. Validation of the query string is
optional. The executeQuery( ) method performs a
query described by a Query object and returns the
results in the form of a BulkResponse.
