Class Mongo

  • Direct Known Subclasses:
    MongoClient
    Deprecated. 
    Replaced by MongoClient. Any non-deprecated methods will be moved to MongoClient. The rest will be removed along with this class.

    @ThreadSafe
@Deprecated
public class Mongo
extends Object

    A database connection with internal connection pooling. For most applications, you should have one Mongo instance for the entire JVM.

    Note: This class has been superseded by MongoClient, and may be deprecated in a future release.

    MongoClient, ReadPreference, WriteConcern

        @Deprecated
public Mongo​()
        Deprecated. Replaced by MongoClient())
        Creates a Mongo instance based on a (single) mongodb node (localhost, default port)
        Throws:
        MongoException - if there's a failure

      • Mongo

        @Deprecated
public Mongo​(String host)
        Deprecated. Replaced by MongoClient(String)
        Creates a Mongo instance based on a (single) mongodb node (default port)
        Parameters:
        host - server to connect to

      • Mongo

        @Deprecated
public Mongo​(String host,
             int port)
        Deprecated. Replaced by MongoClient(String, int)
        Creates a Mongo instance based on a (single) mongodb node
        Parameters:
        host - the host address of the database
        port - the port on which the database is running

        @Deprecated
public Mongo​(List<ServerAddress> seeds)
        Deprecated. Replaced by MongoClient(java.util.List)

        Creates an instance based on a list of replica set members or mongos servers. For a replica set it will discover all members. For a list with a single seed, the driver will still discover all members of the replica set. For a direct connection to a replica set member, with no discovery, use the Mongo(ServerAddress) constructor instead.

        When there is more than one server to choose from based on the type of request (read or write) and the read preference (if it's a read request), the driver will randomly select a server to send a request. This applies to both replica sets and sharded clusters. The servers to randomly select from are further limited by the local threshold. See MongoClientOptions.getLocalThreshold()

        Parameters:
        seeds - Put as many servers as you can in the list and the system will figure out the rest. This can either be a list of mongod servers in the same replica set or a list of mongos servers in the same sharded cluster.

public Mongo​(List<ServerAddress> seeds,
             MongoOptions options)
        Deprecated. Replaced by MongoClient(java.util.List, MongoClientOptions)

        Creates an instance based on a list of replica set members or mongos servers. For a replica set it will discover all members. For a list with a single seed, the driver will still discover all members of the replica set. For a direct connection to a replica set member, with no discovery, use the Mongo(ServerAddress, MongoClientOptions) constructor instead.

        When there is more than one server to choose from based on the type of request (read or write) and the read preference (if it's a read request), the driver will randomly select a server to send a request. This applies to both replica sets and sharded clusters. The servers to randomly select from are further limited by the local threshold. See MongoClientOptions.getLocalThreshold()

        Parameters:
        seeds - Put as many servers as you can in the list and the system will figure out the rest. This can either be a list of mongod servers in the same replica set or a list of mongos servers in the same sharded cluster.

      • Mongo

        @Deprecated
public Mongo​(MongoURI uri)
        Deprecated. Replaced by MongoClient(MongoClientURI)

        Creates a Mongo described by a URI. If only one address is used it will only connect to that node, otherwise it will discover all nodes. If the URI contains database credentials, the database will be authenticated lazily on first use with those credentials.

        Examples:

        • mongodb://localhost
        • mongodb://fred:foobar@localhost/
        Parameters:
        uri - URI to connect to, optionally containing additional information like credentials
        Throws:
        MongoException - if there's a failure
