TAR

Provides functions for work with TAR containers.

public class TarContainer : Container

A type that allows to iteratively read TAR entries from a container provided by a FileHandle.

The TarReader may be helpful in reducing the peak memory usage on certain platforms. However, to achieve this either the TarReader.process(_:) function should be used or both the call to TarReader.read() and the processing of the returned entry should be wrapped inside the autoreleasepool. Since the autoreleasepool is available only on Darwin platforms, the memory reducing effect may be not as significant on non-Darwin platforms (such as Linux or Windows).

The following code demonstrates an example usage of the TarReader:

   let handle: FileHandle = ...
   let reader = TarReader(fileHandle: handle)
   try reader.process { ... }
   ...
   try handle.close()

Note that closing the FileHandle remains the responsibility of the caller.

public struct TarReader

A type that allows to iteratively create TAR containers with the output being written into a FileHandle.

The TarWriter may be helpful in reducing the peak memory usage on certain platforms. However, to achieve this both the creation of TAR entries and the calls to TarWriter should be wrapped inside the autoreleasepool. Since the autoreleasepool is available only on Darwin platforms, the memory reducing effect may be not as significant on non-Darwin platforms (such as Linux or Windows).

The following code demonstrates an example usage of the TarWriter:

   let handle: FileHandle = ...
   let writer = TarWriter(fileHandle: handle)
   try autoreleasepool {
       let entry: TarEntry = ...
       try writer.append(entry)
   }
   try writer.finalize()
   try handle.close()

Note that TarWriter.finalize() must be called after finishing appending entries to the container. In addition, closing the FileHandle remains the responsibility of the caller.
