So models are nodes and ModelTransformations are edges. 40 - 41 -Thus the Model representing the root-model of a tree is also the root of a concrete TransformationTree-Model. 42 - 43 -Second part is object mapping. 44 - 45 -Concrete models contain EObjects as their elements, which are representend by Element-Class in TransformationTree metamodel. 46 - 47 -The Elements of two models are connected with ElementTransformations-Class to model their 48 - 49 -origination relationship in corresponding model transformation. 50 - 51 - 52 - 53 -An abstract example of an instance of this model: 54 - 55 - 56 - 57 -<exmaple_tree> 58 - 59 ----- 60 - 61 -== Extensions == 62 - 63 - 64 - 65 -Two classes are provided by this project to extend functionality of the core model. 66 - 67 - 68 - 69 -TransformationMapping (JavaDoc) 70 - 71 - 72 - 73 -The main propose of this class is generation of a Object mapping during transformation process. 74 - 75 -Therefor it provides different functions for incremental registering of single parent child relations beween EObjects. 76 - 77 -Furthermore, the extension allows to extract the mapping and check completeness of mapped elements against content of transformed models. 78 - 79 - 80 - 81 -TransformationTreeExtensions (JavaDoc) 82 - 83 - 84 - 85 -This class proived all functionalities to easily traverse and search in a TransformationTree. 86 - 87 -Furthermore, it allows to modify trees by creating, deleting or appending new transformations and transformed models. 88 - 89 - 90 - 91 ----- 92 - 93 - 94 - 95 -== Implementation Details == 96 - 97 - 98 - 99 -All references to EObjects are references to a copy of the original EObject. This allows to represent immutable mapping. To reidentify corresponding EObjects TransformationTreeExtensions provides search funtions and matching functionality. 100 - 101 - 102 - 103 -Models in TransformationTrees may be transient. 104 - 105 -This indicates that all references to EObjects in all Elements of the transient model are removed. 106 - 107 -Thus these models can't be source of a new appended tranformation and can not be associated with it's orginal model. 108 - 109 -The main propose of this feature is to improve scalability of TransformationTrees by removing unneccessary references to internal model, but preserve traversing funtionality of the ObjectMapping. 110 - 111 -== Example == 112 - 113 -coming soon 1 +content coming soon
