Detailed Description

template<typename Host>
struct XMLMethodRegistry< Host >::AttributeReaderEntries

Typically statically constructed

Registers procedures to update the host for certain attributes, in two steps: first the accessor which fetches some substructure owned by the host, which is the common step; then, the mutators that rewrite the substructure, each of them associated with one attribute string, and taking a reference to the substructure and a value string.
