Detailed Description▲
Use this class to describe revisions of a type. Compatible revisions can be expressed as increments of the minor version. Breaking changes can be expressed as increments of the major version. The return values of QMetaMethod::revision() and QMetaProperty::revision() can be passed to QTypeRevision::fromEncodedVersion(). The resulting major and minor versions specify in which Qt versions the properties and methods were added.

[constexpr] QTypeRevision::QTypeRevision()▲
[static constexpr] QTypeRevision QTypeRevision::fromEncodedVersion(Integer value)▲
Produces a QTypeRevision from the given value. value encodes both the minor and major versions in the least significant and second least significant byte, respectively.
value must not have any bits outside the least significant two bytes set. Integer needs to be at least 16 bits wide, and must not have a sign bit in the least significant 16 bits.

[static constexpr] QTypeRevision QTypeRevision::fromMajorVersion(Major majorVersion)▲
Produces a QTypeRevision from the given majorVersion with an invalid minor version. majorVersion needs to be a valid segment.

[static constexpr] QTypeRevision QTypeRevision::fromMinorVersion(Minor minorVersion)▲
Produces a QTypeRevision from the given minorVersion with an invalid major version. minorVersion needs to be a valid segment.

[static constexpr] QTypeRevision QTypeRevision::fromVersion(Major majorVersion, Minor minorVersion)▲
Produces a QTypeRevision from the given majorVersion and minorVersion, both of which need to be a valid segments.

[constexpr] bool QTypeRevision::hasMajorVersion() const▲
Returns true if the major version is known, otherwise false.

[constexpr] bool QTypeRevision::hasMinorVersion() const▲
Returns true if the minor version is known, otherwise false.

[constexpr] bool QTypeRevision::isValid() const▲
Returns true if the major version or the minor version is known, otherwise false.

[static constexpr] bool QTypeRevision::isValidSegment(Integer segment)▲
Returns true if the given number can be used as either major or minor version in a QTypeRevision. The valid range for segment is >= 0 and < 255.
[constexpr] quint8 QTypeRevision::majorVersion() const▲
Returns the major version encoded in the revision.
See Also▲
See also hasMajorVersion(), minorVersion()
[constexpr] quint8 QTypeRevision::minorVersion() const▲
Returns the minor version encoded in the revision.
See Also▲
See also hasMinorVersion(), majorVersion()
[constexpr] Integer QTypeRevision::toEncodedVersion() const▲
Transforms the revision into an integer value, encoding the minor version into the least significant byte, and the major version into the second least significant byte.
Integer needs to be at least 16 bits wide, and must not have a sign bit in the least significant 16 bits.

[static constexpr] QTypeRevision QTypeRevision::zero()▲
Produces a QTypeRevision with major and minor version 0.
