This fixes a minor issue which was found when enabling the
-Wvalue-discard
option.In short, currently if an object has a
hasName
association which is later removed, the value is not actually updated in the in-memory index. This would be corrected upon next service restart when the the IndexData instance is rebuilt (since the bug is only in the index, not the actual triple store).The fix probably has negligible real-world effects, but I used it as a way to get more familiar with the workings of the
IndexData
code.In order to reduce the surface area of the IndexData interface, I also added a trait
StatementSource
including the subset ofTripleStoreConnection
relating only to reading existing statements.
