| The Public2Private ATL transformation makes all public attributes of a UML 1.4 model private. |
| Getters and setters are also created appropriately (i.e. no setter for a frozen attribute). |
| |
| This transformation uses ATL refining mode as defined in [1]: |
| "In ATL, source models are read-only and target models are write-only; |
| this prohibits in-place transformations. However, such transformations are |
| quite common in certain domains. Therefore, ATL provides a mechanism to |
| answer this need: refining mode. This mode can be used for transformations |
| having the same source and target metamodel. Unmatched source elements are |
| automatically copied into target model, as if a default copying rule was |
| present." |
| |
| Thanks to refining mode, only two rules have to be written: one for read-only (i.e. "frozen" |
| in UML terminology) attributes and one for read-write attributes. |
| |
| Source and target models conform to UML the 1.4 metamodel provided as UMLDI.xmi. |
| A sample source model (PetriNet.xmi) and its corresponding target model (PetriNet-Privatized.xmi) are given. |
| Both models are also given in PNG format for easy visualization. |
| Additional source models may be created using Poseidon (http://www.gentleware.com/). |
