public class SevenZOutputFile extends Object implements Closeable
| Constructor and Description | 
|---|
| SevenZOutputFile(File filename)Opens file to write a 7z archive to. | 
| SevenZOutputFile(SeekableByteChannel channel)Prepares channel to write a 7z archive to. | 
| Modifier and Type | Method and Description | 
|---|---|
| void | close()Closes the archive, calling  finish()if necessary. | 
| void | closeArchiveEntry()Closes the archive entry. | 
| SevenZArchiveEntry | createArchiveEntry(File inputFile,
                  String entryName)Create an archive entry using the inputFile and entryName provided. | 
| void | finish()Finishes the addition of entries to this archive, without closing it. | 
| void | putArchiveEntry(ArchiveEntry archiveEntry)Records an archive entry to add. | 
| void | setContentCompression(SevenZMethod method)Sets the default compression method to use for entry contents - the
 default is LZMA2. | 
| void | setContentMethods(Iterable<? extends SevenZMethodConfiguration> methods)Sets the default (compression) methods to use for entry contents - the
 default is LZMA2. | 
| void | write(byte[] b)Writes a byte array to the current archive entry. | 
| void | write(byte[] b,
     int off,
     int len)Writes part of a byte array to the current archive entry. | 
| void | write(int b)Writes a byte to the current archive entry. |

Currently only SevenZMethod.COPY, SevenZMethod.LZMA2, SevenZMethod.BZIP2 and SevenZMethod.DEFLATE are supported.
