Examples of DatabaseQuery

oracle.toplink.essentials.queryframework.DatabaseQuery
Purpose: Abstract class for all database query objects. DatabaseQuery is a visible class to the TopLink user. Users create an appropriate query by creating an instance of a concrete subclasses of DatabaseQuery.
Responsibilities:
- Provide a common protocol for query objects.
- Defines a generic execution interface.
- Provides query property values
- Holds arguments to the query
