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.

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'.
