Package mazealgo.model.server

Class SolutionCache

java.lang.Object

mazealgo.model.server.SolutionCache

public class SolutionCache
extends Object

Caches solved Solutions on disk keyed by SHA-256 of the maze's byte representation. A second solve request for the same maze short-circuits the search and reads the cached solution instead — orders of magnitude faster than re-running BestFirstSearch.

Storage layout: one serialized Solution per file under the configured directory (default $TMPDIR/MazeAlgo/cache), named <sha256>.sol.
