| /** | |||||
| * 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. <p> | |||||
| * | |||||
| * 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. <p> | |||||
| * | |||||
| * 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. <p> | |||||
| * | |||||
| * 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. <p> | |||||
| * | |||||
| * The C structure for a Tar Entry's header is: <pre> | |||||
| * struct header { | |||||
| * char name[NAMSIZ]; | |||||
| * char mode[8]; | |||||
| * char uid[8]; | |||||
| * char gid[8]; | |||||
| * char size[12]; | |||||
| * char mtime[12]; | |||||
| * char chksum[8]; | |||||
| * char linkflag; | |||||
| * char linkname[NAMSIZ]; | |||||
| * char magic[8]; | |||||
| * char uname[TUNMLEN]; | |||||
| * char gname[TGNMLEN]; | |||||
| * char devmajor[8]; | |||||
| * char devminor[8]; | |||||
| * } header; | |||||
