static

This function serves a similar purpose as RequireCompleteType above, but it avoids completing the type if it is not immediately necessary.

It only ensures we can complete the type later.

RequireCompleteType()

static void RequireCompleteType ( CompilerType  type )

static

Complete a type from debug info, or mark it as forcefully completed if there is no definition of the type in the current Module.

Call this function in contexts where the usual C++ rules require a type to be complete (base class, member, etc.).
