• Issue number: #56

Task Description

Every net.splitcells.dem.object.Discoverable needs a unique path, as otherwise this will only cause website server issues during request routing. The existing Discoverable does not enforce anything. Enforce this by adding a manager attribute to every Discoverable, that manages all complex actions and Discoverable constructions. Make the whole discovery tree traversable via the root node, in order support querying the tree.

Tasks

• [x] Create Discovery interface as a manager for each Discoverable.
• [x] Implement Discovery interface.
• [x] Document interface.
• [x] Test Discovery implementation.
• [x] Use Dem#process specific Discovery option, that is the root of all Discoveries.
• [x] Make Discovery tree traversable.
• [x] Optionally check unique Discoverable paths via Discoveries provided by Discoverable. Every Discoverable with a none empty Discovery, has a unique discoverable path.
• [o] Create a renderer for Discovery elements. See DiscoveryRenderer. -> Add the required functionality to ObjectsMediaRendererI instead of DiscoveryRenderer, as this whole thing is just about the paths. DiscoveryRenderer is deleted.
  • [o] Implement DiscoveryRendererImpl like ObjectsMediaRendererI.
  • [o] Test it with one element as a proof of concept.
  • [o] Enable DiscoveryRendererImpl on website server.
• [ ] Add optional Rendering via Discovery ObjectsMediaRendererI
  • [x] Check if Discovery is present and use its path instead.
  • [ ] Implement Discovery for MetaCounter, so it can be used for the unit test.
  • [ ] Unit test ObjectsMediaRendererI.
• [ ] Deprecate Discoverable and Discoverable#path.
• [ ] Migrate all API usage to the optional check method.
• [ ] Make optional check method mandatory by setting Discoveries#ENFORCE_PATH_IDENTITY to true.
• [ ] Convert the unique Discoverable paths check, with an enforcement.
• [ ] Remove Discoverable construction without enforcement.
• [ ] Update Network objectives at projects/net.splitcells.network/src/main/xml/net/splitcells/network/objectives.xml, as this becomes the main Java implementation regarding the semantic inventory system.
• [ ] Enforce via an extra check, that the Discovery is a tree.
• [ ] Update Network subproject objectives regarding the status of this: net/splitcells/network/objectives.xml
