function RendererInterface::hasRenderContext

Checks whether a render context is active.

This is useful only in very specific situations to determine whether the system is already capable of collecting bubbleable metadata. Normally it should not be necessary to be concerned about this.

Return value

bool TRUE if the renderer has a render context active, FALSE otherwise.
