net.i2p.data.DateAndFlags

All Implemented Interfaces:: Serializable, DataStructure

Direct Known Subclasses:: SendMessageOptions

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. See extending class net.i2p.client.SendMessageOptions for more info. If we really need some more bits we could use the first few bits of the third byte.

  Parameters:
  
  flags - 0 - 65535
- DateAndFlags
  
  public DateAndFlags(Date date, int flags)
  
  Parameters:
  
  flags - 0 - 65535
Method Details
- 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. Warning - many classes will throw IllegalStateException if data is already set.
  
  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
- toByteArray
  
  public byte[] toByteArray()
  
  Overridden for efficiency.
  
  Specified by:
  
  toByteArray in interface DataStructure
  
  Overrides:
  
  toByteArray in class DataStructureImpl
  
  Returns:
  
  may be null if data is not set
- fromByteArray
  
  public void fromByteArray(byte[] data) throws DataFormatException
  
  Overridden for efficiency.
  
  Specified by:
  
  fromByteArray in interface DataStructure
  
  Overrides:
  
  fromByteArray in class DataStructureImpl
  
  Parameters:
  
  data - non-null
  
  Throws:
  
  DataFormatException - if null or wrong length
- equals
  
  public boolean equals(Object object)
  
  Overrides:
  
  equals in class Object
- hashCode
  
  public int hashCode()
  
  Overrides:
  
  hashCode in class Object
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class Object
