Member Function Documentation

activate()

virtual void mbgl::gfx::RendererBackend::activate ( )

protectedpure virtual

Called when the backend's GL context needs to be made active or inactive. These are called, as a matched pair, exclusively through BackendScope, in two situations:

1. When releasing GL resources during Renderer destruction (Including calling CustomLayerHost::deinitialize during RenderCustomLayer destruction)
2. When renderering through Renderer::render() (Including calling CustomLayerHost::initialize for newly added custom layers and CustomLayerHost::deinitialize on layer removal)
