Detailed Description

OpenGL backend implementation of RDevice.

Represents a single GPU driven through EGL and OpenGL ES. It owns the device's EGL display, the main-thread EGL context and Skia GrDirectContext, and the associated EGL/GL extension tables. Because contexts are per-thread, eglContext() and skContext() return the objects bound to the calling thread (lazily created as shared contexts on non-main threads).

Obtain it from an RDevice via RDevice::asGL().

Member Function Documentation

core()

RGLCore & core ( )

inlinenoexcept

Returns the owning core as an RGLCore.

eglDisplay()

EGLDisplay eglDisplay ( ) const

inlinenoexcept

Returns the EGL display associated with this device.

eglContext()

EGLContext eglContext ( ) const

noexcept

Returns the EGL context for the calling thread.

On the main thread this is the device's primary context; on other threads a shared context is created on first use. Returns EGL_NO_CONTEXT if none could be obtained.

eglDevice()

EGLDeviceEXT eglDevice ( ) const

inlinenoexcept

Returns the EGLDeviceEXT backing this device, if any.

skContext()

sk_sp< GrDirectContext > skContext ( ) const

noexcept

Returns the Skia GrDirectContext for the calling thread.

Like eglContext(), this is per-thread: the main-thread context on the main thread, or a thread-local context created alongside the shared EGL context otherwise.

eglDisplayProcs()

const REGLDisplayProcs & eglDisplayProcs ( ) const

inlinenoexcept

Returns the display-level EGL function pointers for this device.

eglDisplayExtensions()

const REGLDisplayExtensions & eglDisplayExtensions ( ) const

inlinenoexcept

Returns the display-level EGL extensions supported by this device.

eglDeviceExtensions()

const REGLDeviceExtensions & eglDeviceExtensions ( ) const

inlinenoexcept

Returns the device-level EGL extensions supported by this device.

glExtensions()

const RGLExtensions & glExtensions ( ) const

inlinenoexcept

Returns the OpenGL ES extensions supported by this device's context.

wait()

void wait ( )

overridevirtualnoexcept

Blocks until all GL commands submitted on this device's context have completed.

Makes the device's context current and issues a glFinish().

Implements RDevice.
