WireOutput
Classes inheriting WireOutput concern themselves with sending data back to the client using PG wire protocol. These classes function similarly to com.google.cloud.spanner.pgadapter.wireprotocol.WireMessage in that they use the constructor to instantiate items, but require send to be called to actually send data. Here, you must override postSend with data you wish to send. Note that this subclass will handle sending the identifier and length (provided you initialize them correctly through getIdentifier and he constructor respectively) via send, so you just have to implement payload sending.
