67 | * Abstract implementation of ITmfTrace. |
68 | * <p> | |
13cb5f43 FC |
69 | * Since the concept of 'location' is trace specific, the concrete classes have |
70 | * to provide the related methods, namely: | |
71 | * <ul> | |
72 | * <li> public ITmfLocation<?> getCurrentLocation() | |
73 | * <li> public double getLocationRatio(ITmfLocation<?> location) | |
74 | * <li> public ITmfContext seekEvent(ITmfLocation<?> location) | |
75 | * <li> public ITmfContext seekEvent(double ratio) | |
da1a4b39 | 76 | * <li> public IStatus validate(IProject project, String path) |
13cb5f43 FC |
77 | * </ul> |
78 | * A concrete trace must provide its corresponding parser. A common way to | |
79 | * accomplish this is by making the concrete class extend TmfTrace and | |
80 | * implement ITmfEventParser. | |
81 | * <p> | |
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. | |
