  - select
```
void select(java.lang.Iterable<Node> nodes)
```
    Select the Nodes to which to send requests. This is called with a mutable Iterable of Nodes in the order that the rest client would prefer to use them and implementers should remove nodes from the that should not receive the request. Implementers may iterate the nodes as many times as they need.
    This may be called twice per request: first for "living" nodes that have not been denylisted by previous errors. If the selector removes all nodes from the list or if there aren't any living nodes then the ApacheHttpClient5Transport will call this method with a list of "dead" nodes.
    Implementers should not rely on the ordering of the nodes.
    
    Parameters:
    
    nodes - the Nodes targeted for the sending requests
