Detailed Description

template<typename T, class ThreadingPolicy>
class expression_tree::cache_on_assignment< T, ThreadingPolicy >::branch

Implementation of a branch class that performs caching on assignment of its children.

When a caching-on-assignment branch' children are assigned to, the branch checks whether its children are constant. If they are, it applies its operation on them and caches that value.

[inline, virtual]

When this branch has its children modified, check if they are constant. If they are, perform the operation and cache the value.

Reimplemented from expression_tree::detail::default_branch< T, expression_tree::cache_on_assignment, ThreadingPolicy >.
