Class FileCache

java.lang.Object
  spec.io.FileCache

public class FileCache
extends java.lang.Object

This class cache (read only) files in memory, to be able to used in benchmarks to avoid unwanted contention on the file system. Note! This class must be used in a thread safe way. Files should therefore be put in cache by the harness execution. This is done by loading validation files in cache before first execution of the benchmark is started. This is done by loading files in the setupBenchmark method in the benchmarks.
