| 70 | /** |
| 71 | * For convenient implementation of model transformations in Java from PCM |
| 72 | * instances to performance models, the DS provides a so-called ContextWrapper. |
| 73 | * It hides all specified and computed context models from the transformation |
| 74 | * and assists the traversal of a PCM instance. A transformation can instantiate |
| 75 | * a new ContextWrapper upon visiting an EntryLevelSystemCall or |
| 76 | * ExternalCallAction as it is specific for each RDSEFF call. |
| 77 | * |
| 78 | * Transformations must instantiate a ContextWrapper initially when visiting the |
| 79 | * first EntryLevelSystemCall by calling its constructor and passing a reference |
| 80 | * to the current PCM instance, which already includes the specified contexts as |
| 81 | * well as the computed contexts from a former run of the DS. Thus, from an |
| 82 | * EntryLevelSystemCall and the given PCM instance, the ContextWrapper can |
| 83 | * retrieve the called assembly context, allocation context, computed usage |
| 84 | * context, and computed allocation context internally. The ContextWrapper also |
| 85 | * includes functions to retrieve the RDSEFF called by an EntryLevelSystemCall |
| 86 | * or ExternalCallAction, which a transformation needs to continue traversing a |
| 87 | * PCM instance. These functions (getNextSEFF) hide the context-dependent |
| 88 | * traversal through the model via delegation and assembly connectors from the |
| 89 | * transformation. |
| 90 | * |
| 91 | * When a model transformation visits RDSEFF actions, it may call the Context- |
| 92 | * Wrapper for performance annotations, such as branch probabilities, loop |
| 93 | * iteration numbers, or timing values. This information is not contained in the |
| 94 | * parameterized RDSEFF, but only in the computed contexts. The ContextWrapper |
| 95 | * retrieves the information from the computed contexts given for example an |
| 96 | * AbstractBranchTransition or ParametricResourceDemand. |
| 97 | * |
| 98 | * TODO: This class is way too big and needs refactoring. For many methods, it |
| 99 | * would make sense to re-write them so that they only depend on their input |
| 100 | * parameters (and not on the state of the object). This should make it much |
| 101 | * easier to understand the code. Moreover, context-independent methods |
| 102 | * can be outsourced into helper classes. |
| 103 | * |
