Class TunnelBuildMessageBase
java.lang.Object
net.i2p.data.DataStructureImpl
net.i2p.data.i2np.I2NPMessageImpl
net.i2p.data.i2np.TunnelBuildMessageBase
- All Implemented Interfaces:
- DataStructure, I2NPMessage
- Direct Known Subclasses:
- TunnelBuildMessage, TunnelBuildReplyMessage
public abstract class TunnelBuildMessageBase
- extends I2NPMessageImpl
Base for TBM, TBRM, VTBM, VTBRM
Retrofitted over them.
There's really no difference between the build and build reply.
TBM and VBTM (but not TBRM and VTBRM?) messages are modified
in-place by doing a single setRecord(), and retransmitted.
Therefore they are NOT good candidates to use FastI2NPMessageImpl;
the checksum would have to be invalidated with every setRecord().
Which we could do in TBM and VTBM but not TBRM and VTBRM,
but keep it simple for now.

- 0.8.8
