| Modifier and Type | Method and Description | 
|---|---|
| int | available()Get the available data that can be read from the current
 entry in the archive. | 
| boolean | canReadEntryData(ArchiveEntry ae)Whether this class is able to read the given entry. | 
| void | close()Closes this stream. | 
| TarArchiveEntry | getCurrentEntry()Get the current TAR Archive Entry that this input stream is processing | 
| protected byte[] | getLongNameData()Get the next entry in this tar archive as longname data. | 
| ArchiveEntry | getNextEntry()Returns the next Archive Entry in this Stream. | 
| TarArchiveEntry | getNextTarEntry()Get the next entry in this tar archive. | 
| int | getRecordSize()Get the record size being used by this stream's buffer. | 
| protected boolean | isAtEOF() | 
| protected boolean | isEOFRecord(byte[] record)Determine if an archive record indicate End of Archive. | 
| void | mark(int markLimit)Since we do not support marking just yet, we do nothing. | 
| boolean | markSupported()Since we do not support marking just yet, we return false. | 
| static boolean | matches(byte[] signature,
       int length)Checks if the signature matches what is expected for a tar file. | 
| int | read(byte[] buf,

| long | skip(long n)Skips over and discards  nbytes of data from this input
 stream. |

n bytes of data from this input
 stream. The skip method may, for a variety of reasons, end
 up skipping over some smaller number of bytes, possibly 0.
 This may result from any of a number of conditions; reaching end of file
 or end of entry before n bytes have been skipped; are only
 two possibilities. The actual number of bytes skipped is returned. If
 n is negative, no bytes are skipped.skip in class InputStreamn - the number of bytes to be skipped.IOException - if some other I/O error occurs.public boolean markSupported()
