|
52 This class manages the configuration of Test Protocol Module operation in |
|
53 relation to how to handle conflicting services. |
|
54 |
|
55 The class provides a method for the protocol manager to call in order |
|
56 to generate a decision for handling a new operation, with due consideration |
|
57 of any current active operation. |
|
58 |
|
59 Conflict decisions are taken from a Decision Table which is initialised from an |
|
60 external data source during construction. The table is represented as a matrix |
|
61 of decisions organised in rows and columns, representing current operation |
|
62 and new operation, respectively. The UID (unique identifiers) for the external |
|
63 data items are shown in this representation of the table. |

|
87 To retrieve a decision this class performs a table look-up according to the |
|
88 current operation and new operation specified by the caller. The index is |
|
89 calculated using row and column values according to the operation types. |
|
90 Note: the table index equates to (UID value - 1) |
