hasInstance()

static bool score::ApplicationInterface::hasInstance ( )

inlinestaticnoexcept

Whether instance() has anything to return.

instance() dereferences m_instance unconditionally, so calling it with no application built binds a reference to null. Code that can legitimately run outside an application – the gfx graph is driven standalone by the PipeWire round-trip harness and by the corpus renderer – must ask first.
