The demo factory data resource accessor is a proof-of-concept example of an accessor that allows data service resources to create new data service resources in response to creation requests specified as activities within a perform document (as opposed to invocations of a configurable data service's deployment operations). The newly created data service resources are constructed as objects rather than by read configuration files. They are therefore not persisted and will not survive a container restart. We therefore term these 'transient' data service resources.
The demo transient factory data resource accessor can create transient data service resources which utilise demo transient instance data resource accessors (described on the next page).
This accessor provides no properties for any data service resource which uses it.
This data resource accessor is implemented by the following Java class:
uk.org.ogsadai.examples.demoTransientFactory.DemoTransientFactoryDataResourceAccessor
This data resource accessor implements the following interfaces:
Any data service resource accessor which creates new data service resources must have configuration files for the data service resources it creates. For the demo factory data service resource accessor this is the configuration files of a demo instance data resource, which will include an activity configuration file, data resource accessor class configuration file, session configuration file and name file.
These files are constructed automatically by the tools we provide to deploy the demonstration, see transient data service resource factory activity detailed example.
