21 | * TmfDataRequests are used to obtain blocks of contiguous data from a data provider. Open ranges can be used, |
22 | * especially for continuous streaming. | |
8c8bf09f | 23 | * <p> |
12c155f5 FC |
24 | * The request is processed asynchronously by a TmfProvider and, as blocks of data become available, handleData() is |
25 | * invoked synchronously for each block. Upon return, the data instances go out of scope and become eligible for gc. It | |
26 | * is is thus the responsibility of the requester to either clone or keep a reference to the data it wishes to track | |
27 | * specifically. | |
8c8bf09f | 28 | * <p> |
12c155f5 FC |
29 | * This data block approach is used to avoid busting the heap for very large trace files. The block size is |
30 | * configurable. | |
8c8bf09f | 31 | * <p> |
12c155f5 FC |
32 | * The TmfProvider indicates that the request is completed by calling done(). The request can be canceled at any time |
33 | * with cancel(). | |
8c8bf09f ASL |
34 | * <p> |
35 | * Typical usage: | |

37 | * <pre> | |
38 | * <code><i>TmfTimeWindow range = new TmfTimewindow(...); | |
39 | * TmfDataRequest<DataType[]> request = new TmfDataRequest<DataType[]>(DataType.class, 0, NB_EVENTS, BLOCK_SIZE) { | |
40 | * public void handleData() { | |
41 | * DataType[] data = request.getData(); | |
42 | * for (DataType e : data) { | |
43 | * // do something | |
44 | * } | |
45 | * } | |
46 | * public void handleSuccess() { | |
47 | * // do something | |
48 | * } | |
49 | * } | |
50 | * public void handleFailure() { | |
51 | * // do something | |
52 | * } | |
53 | * } | |
54 | * public void handleCancel() { | |
55 | * // do something | |
56 | * } | |
57 | * } | |
58 | * }; | |
59 | * fProcessor.process(request, true); | |

63 | * TODO: Consider decoupling from "time range", "rank", etc and for the more generic notion of "criteria". This would | |
64 | * allow to extend for "time range", etc instead of providing specialized constructors. This also means removing the | |
65 | * criteria info from the data structure (with the possible exception of fNbRequested). The nice thing about it is that | |
66 | * it would prepare us well for the coming generation of analysis tools. | |
