acquire

public C acquire()

process

public void process(C connection,
           boolean dispatch)

Processes a new connection making it idle or active depending on whether requests are waiting to be sent.

A new connection is created when a request needs to be executed; it is possible that the request that triggered the request creation is executed by another connection that was just released, so the new connection may become idle.

If a request is waiting to be executed, it will be dequeued and executed by the new connection.

Parameters:

connection - the new connection

dispatch - whether to dispatch the processing to another thread

send

protected abstract void send(C connection,
        HttpExchange exchange)
