## net.i2p.data
Class TunnelId

    java.lang.Object
      net.i2p.data.DataStructureImpl
          net.i2p.data.TunnelId

All Implemented Interfaces:
  DataStructure

    public class TunnelId

extends DataStructureImpl

Defines the tunnel ID that messages are passed through on a set of routers. This is not globally unique, but must be unique on each router making up the tunnel (otherwise they would get confused and send messages down the wrong one).

  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

                           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

  Overrides:
    `fromByteArray` in class `DataStructureImpl`
  Parameters:
    `data` - non-null
  Throws:
    `DataFormatException` - if null or wrong length
