static final HostConfigEntryResolver EMPTY

An "empty" implementation that does not resolve any entry - i.e., uses the original entry as-is

Method Detail

resolveEffectiveHost

HostConfigEntry resolveEffectiveHost(String host,
                                     int port,
                                     SocketAddress localAddress,
                                     String username,
                                     AttributeRepository context)
                              throws IOException

Invoked when creating a new client session in order to allow for overriding of the original parameters

Parameters:

host - The requested host - never null/empty

port - The requested port

localAddress - Optional binding endpoint for the local peer

username - The requested username

context - An optional "context" provided during the connection request (to be attached to the established session if successfully connected)

Returns:

A HostConfigEntry for the actual target - null if use original parameters. Note: if any identity files are attached to the configuration then they must point to existing locations. This means that any macros such as ~, %d, %h, etc. must be resolved prior to returning the value

Throws:

IOException - If failed to resolve the configuration
