Detailed Description

The ContextInfo class allows for access to metainformation about a context. The information is only valid for the currently active context.

Constructor & Destructor Documentation

glbinding::ContextInfo::ContextInfo ( )

delete

Deleted Constructor; this class is intended to be used without instantiation.

Member Function Documentation

static std::set<gl::GLextension> glbinding::ContextInfo::extensions ( )

static

Gathers information about the available extensions in the current context.

Returns

The list of available extensions known by glbinding.

static std::set<gl::GLextension> glbinding::ContextInfo::extensions ( std::set< std::string > *  unknown )

static

Gathers information about the available extensions in the current context.

Parameters

[out]

unknown

(optional) The list of extension names for available extensions not known by glbinding.

Returns

The list of available extensions known by glbinding.

Deprecated:

This method will be removed in future major releases.

static std::set<gl::GLextension> glbinding::ContextInfo::extensions ( std::set< std::string > &  unknown )

static

Gathers information about the available extensions in the current context.

Parameters

[out]

unknown

The list of extension names for available extensions not known by glbinding.

Returns

The list of available extensions known by glbinding.

static std::string glbinding::ContextInfo::renderer ( )

static

Queries the renderer string.

Returns

The renderer string.

static std::string glbinding::ContextInfo::vendor ( )

static

Queries the vendor string.

Returns

The vendor string.

static Version glbinding::ContextInfo::version ( )

static

Queries the OpenGL feature number.

Returns

The version encoding the OpenGL feature.

static bool glbinding::ContextInfo::supported ( const std::set< gl::GLextension > &  extensions )

static

Queries if all given extensions are supported.

Parameters

[in]

extensions

A set of extensions that are tested for availability in the current context.

Returns

True if all given extensions are supported by the current context.

static bool glbinding::ContextInfo::supported ( const std::set< gl::GLextension > &  extensions, std::set< gl::GLextension > &  unsupported  )

static

Queries if all given extensions are supported.

Parameters

[in]	extensions	A set of extensions that are tested for availability in the current context.
[out]	unknown	The subset of extensions (based on the given extensions) not supported by the current context.

Returns

True if all given extensions are supported by the current context.

static bool glbinding::ContextInfo::supported ( const Version &  version, bool  resolve = false  )

static

Queries all missing extensions and unresolved functions for the given OpenGL feature.

Parameters

[in]	version	The version for which all functions and extensions are checked.
[in]	resolve	Specifies whether or not functions shall be explicitly resolved before querrying their status.

Returns

True if all extensions required for the given feature are supported.

static bool glbinding::ContextInfo::supported ( const Version &  version, std::set< gl::GLextension > &  unsupportedExtensions, std::set< AbstractFunction * > &  unsupportedFunctions, bool  resolve = false  )

static

Queries all missing extensions for the given OpenGL feature.

Parameters

[in]	version	The version for which all functions and extensions are checked.
[out]	unsupportedExtensions	The set of extensions missing by the current context for full feature support.
[out]	unsupportedFunctions	The set of functions that could not be resolved in the current context.
[in]	resolve	Specifies whether or not functions shall be explicitly resolved before querrying their status.

Returns

True if all extensions required for the given feature are supported.
