Class ArchiveStreamFactory

java.lang.Object
kala.compress.archivers.ArchiveStreamFactory
All Implemented Interfaces:
ArchiveStreamProvider
public class ArchiveStreamFactory extends Object implements ArchiveStreamProvider
Creates an Archive[In|Out]putStreams from names or the first bytes of the InputStream. In order to add other implementations, you should extend ArchiveStreamFactory and override the appropriate methods (and call their implementation from super of course). Compressing a ZIP-File: 
 final OutputStream out = Files.newOutputStream(output.toPath());
 ArchiveOutputStream os = new ArchiveStreamFactory().createArchiveOutputStream(ArchiveStreamFactory.ZIP, out);

 os.putArchiveEntry(new ZipArchiveEntry("testdata/test1.xml"));
 IOUtils.copy(Files.newInputStream(file1.toPath()), os);
 os.closeArchiveEntry();

 os.putArchiveEntry(new ZipArchiveEntry("testdata/test2.xml"));
 IOUtils.copy(Files.newInputStream(file2.toPath()), os);
 os.closeArchiveEntry();
 os.close();
Decompressing a ZIP-File: 
 final InputStream is = Files.newInputStream(input.toPath());
 ArchiveInputStream in = new ArchiveStreamFactory().createArchiveInputStream(ArchiveStreamFactory.ZIP, is);
 ZipArchiveEntry entry = (ZipArchiveEntry) in.getNextEntry();
 OutputStream out = Files.newOutputStream(dir.toPath().resolve(entry.getName()));
 IOUtils.copy(in, out);
 out.close();
 in.close();
