java.io.InputStream

java.io.FilterInputStream

org.dspace.content.packager.PackageUtils.UnclosableInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

Enclosing class:

PackageUtils

public static class PackageUtils.UnclosableInputStream
extends FilterInputStream

Stream wrapper that does not allow its wrapped stream to be closed. This is needed to work around problem when loading bitstreams from ZipInputStream. The Bitstream constructor invokes close() on the input stream, which would prematurely end the ZipInputStream. Example:

      ZipEntry ze = zip.getNextEntry();
      Bitstream bs = bundle.createBitstream(new PackageUtils.UnclosableInputStream(zipInput));
