* This class is used as a helper to the tests in org.eclipse.mdm.api.odsadapter.RelationTest | |
* It needs to be here, because BaseEntitySearchQuery is declared as protected | |
* in the org.eclipse.mdm.api.odsadapter.search package. | |
* It makes some sense to leave it protected in that way, because implementing a BaseEntitySearchQuery | |
* requires understanding of the underlying data model which | |
* The RelationTest requires that the related parametersets to a measurement are | |
* loaded. This class provides a JoinConfig which allows this to happen by defining | |
* the way the entities in question have to be joined. | |
* If we wouldn't join the ParameterSet in, the related | |
* entities would not be loaded, and it would be impossible to determine whether there | |
* are any related ParameterSets or not. | |
