The QMessageDataComparator namespace contains types used in specifying the comparison of MessageStore objects with user-defined values.
Defines the comparison operations that can be used to compare data elements of QMessageManager objects for equality and inequality.
| Constant | Value | Description |
|---|---|---|
| QMessageDataComparator::Equal | 0 | Represents the '==' operator. |
| QMessageDataComparator::NotEqual | 1 | Represents the '!=' operator. |
Defines the comparison operations that can be used to compare data elements of QMessageManager objects for inclusion or exclusion.
| Constant | Value | Description |
|---|---|---|
| QMessageDataComparator::Includes | 0 | Represents an operation in which an associated property is tested to determine whether it includes a value. |
| QMessageDataComparator::Excludes | 1 | Represents an operation in which an associated property is tested to determine whether it is equal to the supplied value. |
Defines the comparison operations that can be used to compare data elements of QMessageManager objects, according to a specific relation.
LikeComparator used the same syntax as an SQL like search, namely, '_' matches any single character and '%' matches zero or more characters. '' is used to escape these symbols and itself.
| Constant | Value | Description |
|---|---|---|
| QMessageDataComparator::Like | 0 | Represents a postive match. |
| QMessageDataComparator::NotLike | 1 | Represent a negative match. |
This enum describes additional matching criteria when performing a search.
| Constant | Value | Description |
|---|---|---|
| QMessageDataComparator::MatchCaseSensitive | Qt::MatchCaseSensitive | The key should be case sensitive. Not supported on QMF platform. |
| QMessageDataComparator::MatchFullWord | 128 | The key should only match a complete word. Not supported on Windows and QMF platforms. |
The MatchFlags type is a typedef for QFlags<MatchFlag>. It stores an OR combination of MatchFlag values.
Defines the comparison operations that can be used to compare data elements of QMessageManager objects, according to a specific relation.
| Constant | Value | Description |
|---|---|---|
| QMessageDataComparator::LessThan | 0 | Represents the '<' operator. |
| QMessageDataComparator::LessThanEqual | 1 | Represents the '<=' operator. |
| QMessageDataComparator::GreaterThan | 2 | Represents the '>' operator. |
| QMessageDataComparator::GreaterThanEqual | 3 | Represents the '>= operator'. |
