Class BuildRequestor

java.lang.Object

net.i2p.router.tunnel.pool.BuildRequestor

abstract class BuildRequestor
extends Object

Utility class for creating and dispatching tunnel build request messages.

This class handles:

• Preparation of tunnel hop IDs
• Selection of paired or exploratory tunnels for replies
• Construction of TunnelBuildMessage, including legacy and new-style (Short/Variable) formats
• Garlic encryption for inbound builds
• Timeout and failure handling

Paired tunnels are always used (as of 0.9.50+) to improve client isolation and prevent correlation across tunnel pools.
