Class ZipFile.BoundedFileChannelInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    Enclosing class:
    ZipFile
    private class ZipFile.BoundedFileChannelInputStream
extends BoundedArchiveInputStream
    Lock-free implementation of BoundedInputStream. The implementation uses positioned reads on the underlying archive file channel and therefore performs significantly faster in concurrent environment.
