Method Detail

applySettings

public ClusterSettings.Builder applySettings(ClusterSettings clusterSettings)

Applies the clusterSettings to the builder

Note: Overwrites all existing settings

Parameters:

clusterSettings - the clusterSettings

Returns:

this

Since:

3.7

srvHost

public ClusterSettings.Builder srvHost(String srvHost)

Sets the host name to use in order to look up an SRV DNS record to find the MongoDB hosts.

Note that when setting srvHost via ClusterSettings.Builder, the driver will NOT process any associated TXT records associated with the host. In order to enable the processing of TXT records while still using MongoClientSettings, specify the SRV host via connection string and apply the connection string to the settings, e.g. MongoClientSettings.builder().applyConnectionString(new ConnectionString("mongodb+srv://host1.acme.com")) .

Parameters:

srvHost - the SRV host name

Returns:

this

See Also:

MongoClientSettings.Builder.applyConnectionString(ConnectionString), applyConnectionString(ConnectionString)

srvMaxHosts

public ClusterSettings.Builder srvMaxHosts(Integer srvMaxHosts)

Sets the maximum number of hosts to connect to when using SRV protocol.

Parameters:

srvMaxHosts - the maximum number of hosts to connect to when using SRV protocol

Returns:

this

Since:

4.4

hosts

public ClusterSettings.Builder hosts(List<ServerAddress> hosts)

Sets the hosts for the cluster. Any duplicate server addresses are removed from the list.

Parameters:

hosts - the seed list of hosts

Returns:

this

mode

public ClusterSettings.Builder mode(ClusterConnectionMode mode)

Sets the mode for this cluster.

Parameters:

mode - the cluster connection mode

Returns:

this;

requiredReplicaSetName

public ClusterSettings.Builder requiredReplicaSetName(String requiredReplicaSetName)

Sets the required replica set name for the cluster.

Parameters:

requiredReplicaSetName - the required replica set name.

Returns:

this

requiredClusterType

public ClusterSettings.Builder requiredClusterType(ClusterType requiredClusterType)

Sets the required cluster type for the cluster.

Parameters:

requiredClusterType - the required cluster type

Returns:

this

localThreshold

public ClusterSettings.Builder localThreshold(long localThreshold,
                                              TimeUnit timeUnit)

Sets the local threshold.

Parameters:

localThreshold - the acceptable latency difference, in milliseconds, which must be >= 0

timeUnit - the time unit

Returns:

this

Throws:

IllegalArgumentException - if localThreshold < 0

Since:

3.7

serverSelector

public ClusterSettings.Builder serverSelector(ServerSelector serverSelector)

Adds a server selector for the cluster to apply before selecting a server.

Parameters:

serverSelector - the server selector to apply as selector.

Returns:

this

See Also:

ClusterSettings.getServerSelector()

serverSelectionTimeout

public ClusterSettings.Builder serverSelectionTimeout(long serverSelectionTimeout,
                                                      TimeUnit timeUnit)

Sets the timeout to apply when selecting a server. If the timeout expires before a server is found to handle a request, a MongoTimeoutException will be thrown. The default value is 30 seconds.

A value of 0 means that it will timeout immediately if no server is available. A negative value means to wait indefinitely.

Parameters:

serverSelectionTimeout - the timeout

timeUnit - the time unit

Returns:

this

addClusterListener

public ClusterSettings.Builder addClusterListener(ClusterListener clusterListener)

Adds a cluster listener.

Parameters:

clusterListener - the non-null cluster listener

Returns:

this

Since:

3.3

applyConnectionString

public ClusterSettings.Builder applyConnectionString(ConnectionString connectionString)

Takes the settings from the given ConnectionString and applies them to the builder

Parameters:

connectionString - the connection string containing details of how to connect to MongoDB

Returns:

this

build

public ClusterSettings build()

Build the settings from the builder.

Returns:

the cluster settings
