| /** |
| * Returns the list of binding keys possessing the tModels in the passed tModelBag. |
| * Output is restricted by list of binding keys passed in. If null, all bindings are searched. |
| * Output is produced by building the appropriate JPA query based on input and find qualifiers. |
| * |
| * From specification: |
| * "This collection of tModelKey elements represent in part or in whole the technical fingerprint of the bindingTemplate |
| * structures for which the search is being performed. At least one of either a tModelBag or a find_tModel argument SHOULD be |
| * supplied, unless a categoryBag based search is being used. |
| |
| * If a find_tModel argument is specified (see above), it is treated as an embedded inquiry. The tModelKeys returned as a |
| * result of this embedded find_tModel argument are used as if they had been |
| * supplied in a tModelBag argument. Changing the order of the keys in the collection or specifying the same tModelKey more than |
| * once does not change the behavior of the find. |
| * |
| * By default, only bindingTemplates that have a technical fingerprint containing |
| * all of the supplied tModelKeys match (logical AND). Specifying appropriate findQualifiers can override this behavior so that |
| * bindingTemplates with a technical fingerprint containing any of the specified tModelKeys are returned (logical OR)." |
