Class AbstractServerTransport

java.lang.Object
  org.cometd.common.AbstractTransport
      org.cometd.server.AbstractServerTransport

All Implemented Interfaces:

ServerTransport, Transport

Direct Known Subclasses:

HttpTransport

public abstract class AbstractServerTransport
extends AbstractTransport
implements ServerTransport

The base class of all server transports.

Each derived Transport class should declare all options that it supports by calling AbstractTransport.setOption(String, Object) for each option. Then during the call the init(), each transport should call the variants of AbstractTransport.getOption(String) to obtained the configured value for the option.

Constructor Detail

AbstractServerTransport

protected AbstractServerTransport(BayeuxServerImpl bayeux,
                                  String name)

The constructor is passed the BayeuxServerImpl instance for the transport. The BayeuxServerImpl.getOptions() map is populated with the default options known by this transport. The options are then inspected again when init() is called, to set the actual values used. The options are arranged into a naming hierarchy by derived classes adding prefix by calling add AbstractTransport.setOptionPrefix(String). Calls to AbstractTransport.getOption(String) will use the list of prefixes to search for the most specific option set.

Parameters:

bayeux - the BayeuxServer implementation

name - the name of the transport
