66 | * Abstract implementation of ITmfTrace. |
67 | * <p> | |
13cb5f43 FC |
68 | * Since the concept of 'location' is trace specific, the concrete classes have |
69 | * to provide the related methods, namely: | |
70 | * <ul> | |
71 | * <li> public ITmfLocation<?> getCurrentLocation() | |
72 | * <li> public double getLocationRatio(ITmfLocation<?> location) | |
73 | * <li> public ITmfContext seekEvent(ITmfLocation<?> location) | |
74 | * <li> public ITmfContext seekEvent(double ratio) | |
da1a4b39 | 75 | * <li> public IStatus validate(IProject project, String path) |
13cb5f43 | 76 | * </ul> |
13cb5f43 | 77 | * <p> |
6b44794a MK |
78 | * When constructing an event, the concrete trace should use the trace's |
79 | * timestamp transform to create the timestamp, by either transforming the | |
80 | * parsed time value directly or by using the method createTimestamp(). | |
81 | * <p> | |
13cb5f43 FC |
82 | * The concrete class can either specify its own indexer or use the provided |
83 | * TmfCheckpointIndexer (default). In this case, the trace cache size will be | |
84 | * used as checkpoint interval. | |
