Interface EvaluatorOptions

Kernel id to materialize against. Defaults to the currently-active kernel.

Upper bound on the number of materialized entries kept in the content cache. When the cache exceeds this after a top-level evaluate(), the least-recently-used entries are evicted and their kernel handles disposed (a handle shared by several entries is freed only when its last entry is evicted). Defaults to unbounded — entries live for the Evaluator's lifetime. With a bound set, a returned shape is only guaranteed valid until the next successful evaluate() call; a failed or thrown evaluate() is transactional (the cache is left unchanged), and evaluate() is non-reentrant (calling it from an onStep callback throws). Must be a positive integer.

Upper bound on entries in the Evaluator.evaluateMesh content cache, which is independent of the shape cache. Defaults to unbounded. Bounding it separately is what lets a mesh outlive its (evicted) kernel shape, so a re-evaluateMesh is a pure data hit with no re-materialization. Must be a positive integer.

Optional callback fired after every node visit, including cache hits (info.cacheHit discriminates).

Default boolean tolerance applied when a node doesn't override it.
