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.

Since:

0.8.4

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
