Abstract

There is alteration of a late-bound expression produced by a compiler into an early-bound structure. Alteration of the late-bound expression can occur at runtime and a visitor pattern can be used to create the alteration. In one instance, a conversion from late-bound to early-bound takes place through replacing a late-bound property with a statically typed call. The early-bound structure can translate into an expression tree to enable an implementation of a store specific query operated upon storage.
