Detailed Description

template<class T>
struct line::env::EnvAnalyzerSolution< T >

What the ENV entry reports: the environment-blended metrics, and the whole result of whichever coupling produced them.

The sub-result is kept rather than reduced away because the two couplings report different things beside the means – the mean-field one the per-stage exit metrics and the entry queue lengths its fixed point converged to, the state-vector one the entry and sojourn-end DISTRIBUTIONS and the cache blend – and a caller who chose a coupling chose it for those.

◆ compressed

template<class T>

bool line::env::EnvAnalyzerSolution< T >::compressed = false

True when the environment was aggregated before the coupling ran.

◆ compression

template<class T>

EnvCompression<T> line::env::EnvAnalyzerSolution< T >::compression {}

The aggregation, when there was one; its eps against epsMAX says whether it was meaningful.

Definition at line 94 of file env_dispatch.h.

◆ converged

template<class T>

bool line::env::EnvAnalyzerSolution< T >::converged = false

True on the limit path: a closed form has converged by construction.

The flag says whether the numbers can be trusted as the method's own answer, not whether a loop ended, and a limit's answer is always its own.

Definition at line 112 of file env_dispatch.h.

◆ iterations

template<class T>

int line::env::EnvAnalyzerSolution< T >::iterations = 0

ZERO ON THE LIMIT PATH, and that is the answer rather than a gap: a limit reads the environment once and iterates nothing, so reporting an iteration count would describe a fixed point that never ran.
