  • public class ServerFactory
extends java.lang.Object
    The main P4Java server factory class. This class is used to obtain an IServer interface onto a particular Perforce server using a specific (or default) protocol. Usage is described below with the getServer method.

      Return an IOptionsServer onto an underlying Perforce server at the host address specified by serverUriString using the protocol implementation and passed-in properties and a default UsageOptions object.

      static IServer getServer​(java.net.URI serverUrl, java.util.Properties props)
      Deprecated.
      as of the 2009.2 release, use the getServer(String, Properties) method due to that Java's URI class does not accept hostnames with anything other than alphanumeric characters: even common hostnames like "perforce_p" will fail, often silently.
      static java.util.List<ZeroconfServerInfo> getZeroconfServers()
      Deprecated.
      As of release 2013.1, ZeroConf is no longer supported by the Perforce server 2013.1.
      static boolean isZeroConfAvailable()
      Deprecated.
      As of release 2013.1, ZeroConf is no longer supported by the Perforce server 2013.1.
      static void setRpcFileSystemHelper​(ISystemFileCommandsHelper fsCmdHelper)
      Register an ISystemFileCommandsHelper for the RPC implementations.

        public static final java.lang.String DEFAULT_PROTOCOL_NAME
        Default protocol name, i.e. the name used when the protocol name is specified as "p4java" in a suitable URL. Currently it always maps to the native RPC implementation, but this is not guaranteed.

      • getServer

        public static IServer getServer​(java.lang.String serverUriString,
                                java.util.Properties props)
                         throws java.net.URISyntaxException,
                                ConnectionException,
                                NoSuchObjectException,
                                ConfigException,
                                ResourceException
        Return an IServer interface onto an underlying Perforce server at the host address specified by serverUriString using the protocol implementation and passed-in properties. Note that we use the term "URL" here a lot when we typically mean "URI"; this is mostly done to pre-empt confusion, but we may tighten usage up a lot over time.

        The format of the server URI string is protocol + "://" + hostaddr [+ ":" + port] [+ queryString], e.g. "p4java://example.perforce.com:1666" or "p4java://192.168.1.2:1999" or p4jrpc://example.perforce.com:1199?progName=p4javaTest21&progVersion=Alpha203B The protocol, port, and hostaddr fields can't be missing, but the port and hostaddr fields can be anything acceptable to the protocol, e.g. typically something like an IP address or hostname coupled with a port number.

        The protocol part specifies which network implementation to use; the value "p4java" (DEFAULT_PROTOCOL_NAME) will tell the factory to use the default protocol, the details of which are not spelled out here, and which should always be used unless you have good reason to use an alternative (other protocol part values are possible, but should not generally be used unless suggested by Perforce support staff).

        To connect to an SSL-enabled Perforce server, use one of the SSL protocols defined in the IServerAddress.Protocol enum (i.e. "p4javassl", "p4rpcssl" or "p4jrpcntsssl").

        For advanced users, the optional queryString part can be used to set P4Java properties from the URI; these override any correspondingly-named properties sent programmatically through the props parameter (see next paragraph). These URI query strings are not interpreted, but are simply put as-is into the properties passed to the individual server implementation class. Note: this method does not do any query string replacement of things like %20 to spaces, etc. (this really isn't needed here as the query parts are passed as-is to the underlying implementation(s)).

        The props argument can be used to pass in any protocol-specific properties; these are typically described in usage or implementation notes supplied elsewhere, and are not typically used by end-users.

        IServer objects returned by this method may have been retrieved from a cache of previously-used objects, but they are guaranteed to be ready for use by the consumer, and to be for that consumer's exclusive use only.

        Parameters:
        serverUriString - non-null server address in URI form.
        props - protocol-specific properties; may be null
        Returns:
        a non-null IServer object ready for use by the consumer.
        Throws:
        java.net.URISyntaxException - if the passed-in URI string does not conform to the Perforce URI specs detailed above.
        ConnectionException - if the factory is unable to connect to the server named by serverUrl
        NoSuchObjectException - if no implementation class can be found for the protocol specified in the passed-in URI protocol (scheme part);
        ConfigException - if the underlying protocol supplier detects a misconfiguration
        ResourceException - if the factory does not have the resources available to service the request

      • setRpcFileSystemHelper

        public static void setRpcFileSystemHelper​(ISystemFileCommandsHelper fsCmdHelper)
        Register an ISystemFileCommandsHelper for the RPC implementations. See the documentation for the ISystemFileCommandsHelper interface for more semantic and usage details.

        Helper classes are needed for certain hosted implementations and for some JDK 5 installations, and are shared across an entire instance of P4Java. Please do not register a helper class unless you know what you're doing and you're OK with the dire consequences of getting a helper class implementation wrong.

        Note that if the fsCmdHelper parameter is null, the default internal implementation will be used, which is usually fine for JDK 6 systems.

        Parameters:
        fsCmdHelper - file helper interface implementation; if null, use the JVM default implementation(s).

        ISystemFileCommandsHelper

      • getRpcFileSystemHelper

        public static ISystemFileCommandsHelper getRpcFileSystemHelper()
        Returns:
        the current SystemFileCommands helper, if any.

      • getZeroconfServers

        @Deprecated
public static java.util.List<ZeroconfServerInfo> getZeroconfServers()
                                                             throws ConfigException
        Deprecated.
        As of release 2013.1, ZeroConf is no longer supported by the Perforce server 2013.1.
        Return a list of Perforce servers registered locally with zeroconf at the time the method was called. See the Perforce knowledge base articles at http://kb.perforce.com/AdminTasks/Zeroconf for an introduction to Perforce zeroconf usage, and zeroconf.org for zeroconf in general.

        This method uses the javax.jmdns JmDNS package (available through Sourceforge, etc.), and that package must be visible to the current class loader for this method to work. If the server factory is unable to find a suitable JmDNS package using the current class loader, this method will throw a ConfigException. The JmDNS package is not supplied with P4Java and must be downloaded and installed separately.

        Note that zeroconf discovery can take some time (in the order of tens of seconds in some cases), and only works for local subnets, so the first call to this method may return nothing even though there's a suitable server out there on the same subnet. Subsequent calls are usually more successful.

        Note also that we recommend you call the associated isZeroconfAvailable method first to check whether zeroconf is even available for this P4Java instance -- this can save a lot of overhead and / or annoying log messages.

        Returns:
        non-null (but possibly-empty) list of ZeroconfServerInfo objects for Perforce servers registered when this method is called.
        Throws:
        ConfigException - if the server factory can't load and use a suitable JmDNS zeroconf package using the current class loader.

      • isZeroConfAvailable

        @Deprecated
public static boolean isZeroConfAvailable()
        Deprecated.
        As of release 2013.1, ZeroConf is no longer supported by the Perforce server 2013.1.
        Returns true if the server factory has a suitable zeroconf service browsing implementation available to it. Should probably be used at least once before calling the getZeroConfServers method to avoid unnecessary overhead.
        Returns:
        true iff zeroconf browsing services are available to the server factory.
