## Class DateAndFlags

- java.lang.Object
- - net.i2p.data.DataStructureImpl
  - - net.i2p.data.DateAndFlags

- All Implemented Interfaces:
    DataStructure

      public class DateAndFlags
      extends DataStructureImpl

  A six-byte Date and 2 bytes of flags, since a Date won't encroach on the top two bytes until the year 10889. The flag format is not specified here. The bits may be used in an application-specific manner. The application should be designed so that a flags value of 0 is the default, for compatibility with an 8-byte Date. If we really need some more bits we could use the first few bits of the third byte.

    - #### DateAndFlags

          public DateAndFlags()

    - #### DateAndFlags

          public DateAndFlags(long date,
                      int flags)

      Parameters:
        `flags` - 0 - 65535

    - #### DateAndFlags

          public DateAndFlags(Date date,
                      int flags)

      Parameters:
        `flags` - 0 - 65535

  - ### Method Detail

    - #### getFlags

          public int getFlags()

    - #### setFlags

          public void setFlags(int flags)

      Parameters:
        `flags` - 0 - 65535

    - #### getDate

          public Date getDate()

      The Date object is created here, it is not cached. Use getTime() if you only need the long value.

    - #### getTime

          public long getTime()

    - #### setDate

          public void setDate(long date)

    - #### setDate

          public void setDate(Date date)

    - #### readBytes

          public void readBytes(InputStream in)
                         throws DataFormatException,
                                IOException

      Description copied from interface: `DataStructure`
      Load up the current object with data from the given stream. Data loaded this way must match the I2P data structure specification.
      Parameters:
        `in` - stream to read from
      Throws:
        `DataFormatException` - if the data is improperly formatted
        `IOException` - if there was a problem reading the stream

    - #### writeBytes

          public void writeBytes(OutputStream out)
                          throws DataFormatException,
                                 IOException

      Description copied from interface: `DataStructure`
      Write out the data structure to the stream, using the format defined in the I2P data structure specification.
      Parameters:
        `out` - stream to write to
      Throws:
        `DataFormatException` - if the data was incomplete or not yet ready to be written
        `IOException` - if there was a problem writing to the stream
