◆ GetBackendType()

Context::BackendType impeller::ContextGLES::GetBackendType ( ) const

overridevirtual

Get the graphics backend of an Impeller context.

        This is useful for cases where a renderer needs to track and
        lookup backend-specific resources, like shaders or uniform
        layout information.

        It's not recommended to use this as a substitute for
        per-backend capability checking. Instead, check for specific
        capabilities via `GetCapabilities()`.

Returns: The graphics backend of the Context.

Implements impeller::Context.
