All Implemented Interfaces:: ArchiveEntry, TarConstants

public class TarArchiveEntry
extends java.lang.Object
implements ArchiveEntry, TarConstants

This class represents an entry in a Tar archive. It consists of the entry's header, as well as the entry's File. Entries can be instantiated in one of three ways, depending on how they are to be used.

TarEntries that are created from the header bytes read from an archive are instantiated with the TarEntry( byte[] ) constructor. These entries will be used when extracting from or listing the contents of an archive. These entries have their header filled in using the header bytes. They also set the File to null, since they reference an archive entry not a file.

TarEntries that are created from Files that are to be written into an archive are instantiated with the TarEntry( File ) constructor. These entries have their header filled in using the File's information. They also keep a reference to the File for convenience when writing entries.

Finally, TarEntries can be constructed from nothing but a name. This allows the programmer to construct the entry by hand, for instance when only an InputStream is available for writing to the archive, and the header information is constructed from other information. In this case the header fields are set to defaults and the File is set to null.

The C structure for a Tar Entry's header is:

 struct header {
 char name[100];     // TarConstants.NAMELEN    - offset   0
 char mode[8];       // TarConstants.MODELEN    - offset 100
 char uid[8];        // TarConstants.UIDLEN     - offset 108
 char gid[8];        // TarConstants.GIDLEN     - offset 116
 char size[12];      // TarConstants.SIZELEN    - offset 124
 char mtime[12];     // TarConstants.MODTIMELEN - offset 136
 char chksum[8];     // TarConstants.CHKSUMLEN  - offset 148
 char linkflag[1];   //                         - offset 156
 char linkname[100]; // TarConstants.NAMELEN    - offset 157
 The following fields are only present in new-style POSIX tar archives:
 char magic[6];      // TarConstants.MAGICLEN   - offset 257
 char version[2];    // TarConstants.VERSIONLEN - offset 263
 char uname[32];     // TarConstants.UNAMELEN   - offset 265
 char gname[32];     // TarConstants.GNAMELEN   - offset 297
 char devmajor[8];   // TarConstants.DEVLEN     - offset 329
 char devminor[8];   // TarConstants.DEVLEN     - offset 337
 char prefix[155];   // TarConstants.PREFIXLEN  - offset 345
 // Used if "name" field is not long enough to hold the path
 char pad[12];       // NULs                    - offset 500
 } header;
 All unused bytes are set to null.
 New-style GNU tar files are slightly different from the above.
 For values of size larger than 077777777777L (11 7s)
 or uid and gid larger than 07777777L (7 7s)
 the sign bit of the first byte is set, and the rest of the
 field is the binary representation of the number.
 See TarUtils.parseOctalOrBinary.

The C structure for a old GNU Tar Entry's header is:

 struct oldgnu_header {
 char unused_pad1[345]; // TarConstants.PAD1LEN_GNU       - offset 0
 char atime[12];        // TarConstants.ATIMELEN_GNU      - offset 345
 char ctime[12];        // TarConstants.CTIMELEN_GNU      - offset 357
 char offset[12];       // TarConstants.OFFSETLEN_GNU     - offset 369
 char longnames[4];     // TarConstants.LONGNAMESLEN_GNU  - offset 381
 char unused_pad2;      // TarConstants.PAD2LEN_GNU       - offset 385
 struct sparse sp[4];   // TarConstants.SPARSELEN_GNU     - offset 386
 char isextended;       // TarConstants.ISEXTENDEDLEN_GNU - offset 482
 char realsize[12];     // TarConstants.REALSIZELEN_GNU   - offset 483
 char unused_pad[17];   // TarConstants.PAD3LEN_GNU       - offset 495
 };

Whereas, "struct sparse" is:

 struct sparse {
 char offset[12];   // offset 0
 char numbytes[12]; // offset 12
 };

The C structure for a xstar (Jrg Schilling star) Tar Entry's header is:

 struct star_header {
  char name[100];               // offset   0
  char mode[8];         // offset 100
  char uid[8];          // offset 108
  char gid[8];          // offset 116
  char size[12];                // offset 124
  char mtime[12];               // offset 136
  char chksum[8];               // offset 148
  char typeflag;                // offset 156
  char linkname[100];           // offset 157
  char magic[6];                // offset 257
  char version[2];              // offset 263
  char uname[32];               // offset 265
  char gname[32];               // offset 297
  char devmajor[8];             // offset 329
  char devminor[8];             // offset 337
  char prefix[131];             // offset 345
  char atime[12];             // offset 476
  char ctime[12];             // offset 488
  char mfill[8];              // offset 500
  char xmagic[4];             // offset 508  "tar"
 };

which is identical to new-style POSIX up to the first 130 bytes of the prefix.
