Detailed Description

Class representing an EGL context.

Member Typedef Documentation

GLProcPointer

typedef void(* kanzi::EGLContext::GLProcPointer) ()

Pointer to GL function.

Constructor & Destructor Documentation

EGLContext() [1/3]

kanzi::EGLContext::EGLContext ( )

explicit

Default constructor, creates a no context.

Postcondition

egl::getError() returns EGL_SUCCESS.

EGLContext() [2/3]

kanzi::EGLContext::EGLContext ( const EGLDisplay &  eglDisplay, const EGLConfig &  eglConfig, ::EGLContext  sharedContext, EGLint  contextClientVersion  )

explicit

Constructor.

Parameters

eglDisplay	EGL display connection.
eglConfig	EGL configuration to use.
sharedContext	EGL context to share data with.
contextClientVersion	Context client API major version.

Postcondition

egl::getError() returns EGL_SUCCESS.

EGLContext() [3/3]

kanzi::EGLContext::EGLContext ( ::EGLContext  eglContext )

explicit

Constructor.

Parameters

eglContext

EGL context handle.

Postcondition

egl::getError() returns EGL_SUCCESS.

Member Function Documentation

getProcAddress()

static KZ_NO_DISCARD GLProcPointer kanzi::EGLContext::getProcAddress ( const char *  functionName )

static

Retrieves pointer to GL function.

Parameters

functionName

Name of the function.

Returns

Pointer to the function, or null if not found.

getCurrentContext()

static KZ_NO_DISCARD ::EGLContext kanzi::EGLContext::getCurrentContext ( )

static

Gets context for current thread.

Returns

EGL context handle of the current context, or a no context handle if no context is current.

getNoContext()

static KZ_NO_DISCARD ::EGLContext kanzi::EGLContext::getNoContext ( )

staticnoexcept

Gets an no context EGL handle.

Returns

EGL context handle with a value representing no context.

destroy()

bool kanzi::EGLContext::destroy

(

const EGLDisplay &

eglDisplay

)

Destroys EGL context.

Call this before destructing the object.

Parameters

eglDisplay

EGL display connection.

Postcondition

egl::getError() returns EGL_SUCCESS.

getNativeHandle()

KZ_NO_DISCARD ::EGLContext kanzi::EGLContext::getNativeHandle ( ) const

noexcept

Gets EGL context handle.

Returns

EGL context handle.
