Method Detail

• setContentCompression

  public void setContentCompression(SevenZMethod method)

  Sets the default compression method to use for entry contents - the default is LZMA2.

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

  This is a short form for passing a single-element iterable to setContentMethods(java.lang.Iterable<? extends org.apache.commons.compress.archivers.sevenz.SevenZMethodConfiguration>).

• setContentMethods

  public void setContentMethods(Iterable<? extends SevenZMethodConfiguration> methods)

  Sets the default (compression) methods to use for entry contents - the default is LZMA2.

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

  The methods will be consulted in iteration order to create the final output.
