Field Details
- log
  
  protected static com.fishlib.io.logger.Logger log
- NO_VERSION
  
  protected static final int NO_VERSION
  
  The version of data items that predate systematic versioning.
  
  See Also:
  
  Constant Field Values
- BASELINE_VERSION
  
  protected static final int BASELINE_VERSION
  
  The version of any data item that isn't given an explicit version. This should never change.
  
  See Also:
  
  Constant Field Values
- VERSION_INDICATOR
  
  protected static final int VERSION_INDICATOR
  
  This sequence indicates that a version int follows. Where this might be expected, its absence indicates the default or baseline version will be assumed. The value should be negative to avoid any chance of confusion with a size.
  
  See Also:
  
  Constant Field Values
- version
  
  protected int version
Method Details
- prepareVersion
  
  protected void prepareVersion(@NotNull ByteBuffer bodyBuffer)
  
  Put the version bytes into the body buffer. Does not clear or flip the buffer. This is called only by PayloadDataImportChannelItem on behalf of derived classes.
  
  Parameters:
  
  bodyBuffer - the buffer to populate
- getPrimaryType
  
  public DataImportChannelType getPrimaryType()
  
  Description copied from interface: DataImportChannelItem
  
  Get the item type.
  
  Specified by:
  
  getPrimaryType in interface DataImportChannelItem
  
  Returns:
  
  The item type
- getAlternateTypes
  
  public DataImportChannelType[] getAlternateTypes()
  
  Description copied from interface: DataImportChannelItem
  
  Get all alternate types that this item can process as input.
  
  Specified by:
  
  getAlternateTypes in interface DataImportChannelItem
  
  Returns:
  
  The alternate Types
- read
  
  public void read(@NotNull ByteBuffer buffer, byte wireDataType)
  
  Description copied from interface: DataImportChannelItem
  
  Fill this item's contents from the supplied buffer.
  Header data as described in DataImportChannelItem.send(IOJob) will already have been consumed.
  
  Specified by:
  
  read in interface DataImportChannelItem
  
  Parameters:
  
  buffer - The buffer to read data from
  
  wireDataType - the data type from the stream.
- getVersion
  
  public int getVersion()
  
  Description copied from interface: DataImportChannelItem
  
  Get the version of this DataImportChannelItem.
  
  Specified by:
  
  getVersion in interface DataImportChannelItem
  
  Returns:
  
  the version of the DataImportChannelItem.
- getCurrentVersion
  
  public int getCurrentVersion()
  
  Description copied from interface: DataImportChannelItem
  
  Get the latest version supported by this DataImportChannelItem. This is used by abstract implementations to verify the version read off the wire.
  
  Specified by:
  
  getCurrentVersion in interface DataImportChannelItem
  
  Returns:
  
  the latest version supported by this DataImportChannelItem
