Detailed Description

PATypeHolder - Holder class for a potentially abstract type. This uses efficient union-find techniques to handle dynamic type resolution. Unless you need to do custom processing when types are resolved, you should always use PATypeHolders in preference to PATypeHandles.

(

)

const [inline]

get - This implements the forwarding part of the union-find algorithm for abstract types. Before every access to the Type*, we check to see if the type we are pointing to is forwarding to a new type. If so, we drop our reference to the type.
