Method Detail

parseOctal

public static long parseOctal(byte[] header,
                              int offset,
                              int length)

Parse an octal string from a header buffer. This is used for the file permission mode value.

Parameters:

header - The header buffer from which to parse.

offset - The offset into the buffer from which to parse.

length - The number of header bytes to parse.

Returns:

The long value of the octal string.

getOctalBytes

public static int getOctalBytes(long value,
                                byte[] buf,
                                int offset,
                                int length)

Parse an octal integer from a header buffer.

Parameters:

value -

buf - The header buffer from which to parse.

offset - The offset into the buffer from which to parse.

length - The number of header bytes to parse.

Returns:

The integer value of the octal bytes.

getCheckSumOctalBytes

public static int getCheckSumOctalBytes(long value,
                                        byte[] buf,
                                        int offset,
                                        int length)

Parse the checksum octal integer from a header buffer.

Parameters:

value -

buf - The header buffer from which to parse.

offset - The offset into the buffer from which to parse.

length - The number of header bytes to parse.

Returns:

The integer value of the entry's checksum.

getLongOctalBytes

public static int getLongOctalBytes(long value,
                                    byte[] buf,
                                    int offset,
                                    int length)

Parse an octal long integer from a header buffer.

Parameters:

value -

buf - The header buffer from which to parse.

offset - The offset into the buffer from which to parse.

length - The number of header bytes to parse.

Returns:

The long value of the octal bytes.
