Detailed Description

The Version class represents an OpenGL feature, consisting of majow version and minor version, excluding the profile information.

This instance can represent both any officially released OpenGL feature and other combinations of major and minar version and provides methods for validity checking and comparison.

Example code:

const glbinding::Version currentVersion = glbinding::ContextInfo::version();

if (currentVersion >= glbinding::Version(3, 2))
{
    // do something
}

Constructor & Destructor Documentation

glbinding::Version::Version

(

)

Default constructor, resulting in an invalid Version object.

glbinding::Version::Version	(	unsigned char	majorVersion,
		unsigned char	minorVersion
	)

Constructor for a Version object with the given major and minor version.

Parameters

[in]	majorVersion	The major version
[in]	minorVersion	The minor version

glbinding::Version::Version

(

const Version &

version

)

Copy constructor.

Parameters

[in]

version

The Version the data is used from

glbinding::Version::Version

(

Version &&

version

)

Move constructor.

Parameters

[in]

version

The Version the data is moved from

Member Function Documentation

Version& glbinding::Version::operator=

(

const Version &

version

)

The assignment operator of another Version.

Parameters

[in]

version

The version the data is used from

Returns

The reference to this Version

Version& glbinding::Version::operator=

(

Version &&

version

)

The assignment operator of another Version that is moved from.

Parameters

[in]

version

The version the data is moved from

Returns

The reference to this Version

bool glbinding::Version::operator<

(

const Version &

version

)

const

Operator for lesser comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is lesser than the other Version

bool glbinding::Version::operator>

(

const Version &

version

)

const

Operator for greater comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is greater than the other Version

bool glbinding::Version::operator==

(

const Version &

version

)

const

Operator for equal comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is equal to the other Version

bool glbinding::Version::operator!=

(

const Version &

version

)

const

Operator for unequal comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is not equal to the other Version

bool glbinding::Version::operator>=

(

const Version &

version

)

const

Operator for greater equal comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is greater or equal than the other Version

bool glbinding::Version::operator<=

(

const Version &

version

)

const

Operator for lesser equal comparison to another Version.

Parameters

[in]

version

The Version to compare to

Returns

true iff this Version is lesser or equal than the other Version

unsigned char glbinding::Version::majorVersion

(

)

const

Accessor for the major version.

Returns

the major version

unsigned char glbinding::Version::minorVersion

(

)

const

Accessor for the minor version.

Returns

the minor version

std::string glbinding::Version::toString

(

)

const

Create a string representing the Version using the scheme "<majorVersion>.<minorVersion>".

Returns

The version as string, "-.-" iff the string is invalid.

bool glbinding::Version::isValid

(

)

const

Check for validity of this Version, based on the list of all valid OpenGL feautures.

Returns

true iff the version is valid (i.e., if this version is present in the set of valid versions).

bool glbinding::Version::isNull

(

)

const

Check if the Version was constructed using the default constructor.

Returns

true iff the major version is 0.

This method can be used to check if this Version was constructed using the default constructor or is otherwise malformed.

const Version& glbinding::Version::nearest

(

)

const

Returns the nearest valid Version to this Version.

Returns

the nearest valid Version that is either equal or lower than this Version.

static const std::set<Version>& glbinding::Version::versions ( )

static

Accessor for the list of all valid Versions (OpenGL features).

Returns

the set of all valid Versions (= released OpenGL Features).

static const Version& glbinding::Version::latest ( )

static

Return the most current valid Version.

Returns

the most current Version from the set of all valid versions.
