Detailed Description

template<class Allocator = std::allocator<char>>
class ripple::PeerFinder::Livecache< Allocator >

The Livecache holds the short-lived relayed Endpoint messages.

Since peers only advertise themselves when they have open slots, we want these messags to expire rather quickly after the peer becomes full.

Addresses added to the cache are not connection-tested to see if they are connectible (with one small exception regarding neighbors). Therefore, these addresses are not suitable for persisting across launches or for bootstrapping, because they do not have verifiable and locally observed uptime and connectibility information.
