QueryRedirector	Purpose: Query redirection allows for a named or parameterized query (or finder) to dynamically determine how the query is to be executed based on the arguments.

Class Summary

ComplexQueryResult	Purpose: Used to return multiple sets of information from a query.
Cursor	Purpose: Abstract class for CursoredStream and ScrolableCursor
CursoredStream	Purpose: Stream class which is used to deal with large collections returned from TOPLink queries more efficiently.
CursoredStreamPolicy	Purpose: Used to support cursored streams in a read query.
CursorPolicy	Purpose: Abstract class for all Cursor-related policy objects
DatabaseQuery	Purpose: Abstract class for all database query objects.
DataModifyQuery	Purpose: Concrete class used for executing non selecting SQL strings.

DeleteObjectQuery	Purpose: Used for deleting objects.
DirectReadQuery	Purpose: Concrete class to perform a direct read.
DoesExistQuery	Purpose: This should only be used by the descriptor, this should not be executed directly.
EJBQLCall	Purpose: Used as an abstraction of a database invocation.
InMemoryQueryIndirectionPolicy	Purpose: Used to provide the user with a means of contoling the behaviour of in memory queries that access un-instantiated indirection in the query..
InsertObjectQuery	Purpose: Used for inserting new objects into the database.
MethodBaseQueryRedirector	Purpose: Allows a class to be a QueryRedirector without implementing QueryRedirector.
ModifyQuery	Purpose: Abstract class for all modify queries.
ObjectLevelModifyQuery	Purpose: Abstract class for all object modify queries.
ObjectLevelReadQuery	Purpose: Abstract class for all read queries using objects.
QueryByExamplePolicy	Purpose: This policy defines the configuration options for a Query By Example query.
ReadAllQuery	Purpose: Concrete class for all read queries involving a collection of objects.
ReadObjectQuery	Purpose: Concrete class for all read queries involving a single object.
ReadQuery	Purpose: Abstract class for all read queries.
ReportQuery	Purpose: Query for information about a set of objects instead of the objects themselves.
ReportQueryResult	Purpose: A single row (type) result for a ReportQuery Description: Represents a single row of attribute values (converted using mapping) for a ReportQuery.
ScrollableCursor
ScrollableCursorPolicy	PUBLIC: ScrollableCursorPolicy allows for additional options to be specified for ReadAllQuery or DataReadQuery.
SQLCall	Purpose: Used as an abstraction of an SQL call.
StoredProcedureCall	Purpose: Used to define a platform independent procedure call.
UpdateObjectQuery	Purpose: Used for updating existing objects into the database.
ValueReadQuery	Purpose: Concrete class to perform a read of a single data value.
