Detailed Description

template<template< typename > class Policy, typename Input, typename... Ds>
struct typed_map< Policy, Input, Ds >

A unordered map with value type equal to a sum type of input type and one or more distribution types, parameterized by an update Policy.

The Policy parameter defines an injection \(policy: \{D_i\}_{i \in I} \rightarrow \{D_j\}_{j \in J}\), \(J \subseteq I\). This is implemented as typename Policy<D>::type, which may be a bijection (e.g., when updating parameters in the same distributional family) or may not (e.g., a normal approximation).

Template Parameters

Policy	encapsulates the types of distributions that can be returned by get. Must define type with a using-declaration.
I	The input type
Ds	The universe of allowable distribution types
