Package oracle.toplink.queryframework

Interface Summary

Interface	Description
*Call*	Call defines the interface used primarily by TopLink queries and query mechanisms to perform the necessary actions (read, insert, update, delete) on the data store.
*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
Class Description

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.

DataReadQuery Purpose: Concrete class to perform read using raw SQL.

DeleteAllQuery Purpose: Query used to delete a collection of objects

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: 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.

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

ScrollableCursor

ScrollableCursorPolicy

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.

WriteObjectQuery Purpose: Used for inserting or updating objects WriteObjectQuery determines whether to perform a insert or an update on the database.
