Detailed Description

template<auto V, typename Tag>
class axom::slam::policies::CompileTimeValue< V, Tag >

Shared core for a compile-time-known scalar value policy.

The value V is fixed at compile time. The (defaulted) constructor argument exists only to satisfy the uniform policy-construction interface and is asserted to match V.

Provides the generic value() accessor, operator(), and an isValid() delegating to the tag's predicate. Leaf policies derive from this and add their named accessor.

Template Parameters

V	the compile-time value (its type is the policy's IntType).
Tag	a value-policy tag carrying the default value and validity predicate.
