50 \brief The QMessageId class provides a unique identifier for a QMessage message within the |
|
51 scope of the messaging store. |
|
52 |
|
53 A QMessageId can be constructed from a string, or converted to a string with toString(). |
|
54 |
|
55 A QMessageId instance can be tested for validity with isValid(), and compared to other instances |
|
56 for equality. |
|
57 |
|
58 If the message a QMessageId identifies is removed from the messaging store then the identifier |
|
59 will not be reused. |
|
60 |
|
61 The QMessageId implementation should be as small as is practical for the underlying platform. |
