Parameters:

connection - the managed resource

removeConnection

public void removeConnection(reactor.core.Disposable connection)

Description copied from interface: McpTransportSession

Called when the resource is terminating by itself and the transport session does not need to track it anymore.

Specified by:

removeConnection in interface McpTransportSession<reactor.core.Disposable>

Parameters:

connection - the resource to remove from the monitored collection

close

public void close()

Description copied from interface: McpTransportSession
