Package org.brotli.integration

Class BundleChecker

  • All Implemented Interfaces:
    java.lang.Runnable
    public class BundleChecker
extends java.lang.Object
implements java.lang.Runnable
    Decompress files and (optionally) checks their checksums.

    File are read from ZIP archive passed as an array of bytes. Multiple checkers negotiate about task distribution via shared AtomicInteger counter.

    All entries are expected to be valid brotli compressed streams and output CRC64 checksum is expected to match the checksum hex-encoded in the first part of entry name.
