Method Detail

• adjustToLong

   static long adjustToLong(int i)

  Assumes a negative integer really is a positive integer thathas wrapped around and re-creates the original value.

  Parameters:

  i - the value to treat as unsigned int.

• dosToJavaTime

   static long dosToJavaTime(long dosTime)

  Converts DOS time to Java time (number of milliseconds sinceepoch).

  Parameters:

  dosTime - time to convert

• fromDosTime

   static Date fromDosTime(ZipLong zipDosTime)

  Convert a DOS date/time field to a Date object.

  Parameters:

  zipDosTime - contains the stored DOS time.

• reverse

   static Array<byte> reverse(Array<byte> array)

  Reverses a byte[] array. Reverses in-place (thus provided array ismutated), but also returns same for convenience.

  Parameters:

  array - to reverse (mutated in-place, but also returned forconvenience).

• signedByteToUnsignedInt

   static int signedByteToUnsignedInt(byte b)

  Converts a signed byte into an unsigned integer representation(e.g., -1 becomes 255).

  Parameters:

  b - byte to convert to int

• toDosTime

   static ZipLong toDosTime(Date time)

  Convert a Date object to a DOS date/time field.

  Parameters:

  time - the {@code Date} to convert

• toDosTime

   static Array<byte> toDosTime(long t)

  Convert a Date object to a DOS date/time field.

  Stolen from InfoZip's {@code fileio.c}

  Parameters:

  t - number of milliseconds since the epoch

• toDosTime

   static void toDosTime(long t, Array<byte> buf, int offset)

  Convert a Date object to a DOS date/time field.

  Stolen from InfoZip's {@code fileio.c}

  Parameters:

  t - number of milliseconds since the epoch

  buf - the output buffer

  offset - The offset within the output buffer of the first byte to be written.

• unsignedIntToSignedByte

   static byte unsignedIntToSignedByte(int i)

  Converts an unsigned integer to a signed byte (e.g., 255 becomes -1).

  Parameters:

  i - integer to convert to byte
