Constructor Detail

ReplicaSets

public ReplicaSets(Collection<ReplicaSet> rsSpecs)

Create a set of replica set specifications.

Parameters:

rsSpecs - the replica set specifications; may be null or empty

Method Detail

parse

public static ReplicaSets parse(String hosts)

Parse the supplied string for the information about the replica set hosts. The string is a semicolon-delimited list of shard hosts (e.g., "shard01=replicaSet1/host1:27017,host2:27017"), replica set hosts (e.g., "replicaSet1/host1:27017,host2:27017"), and standalone hosts (e.g., "host1:27017" or "1.2.3.4:27017").

Parameters:

hosts - the hosts string; may be null

Returns:

the replica sets; never null but possibly empty

See Also:

hosts()

empty

public static ReplicaSets empty()

Get an instance that contains no replica sets.

Returns:

the empty instance; never null

replicaSetCount

public int replicaSetCount()

Get the number of replica sets.

Returns:

the replica set count

validReplicaSetCount

public int validReplicaSetCount()

Get the number of replica sets with names.

Returns:

the valid replica set count

onEachReplicaSet

public void onEachReplicaSet(Consumer<ReplicaSet> function)

Perform the supplied function on each of the replica sets

Parameters:

function - the consumer function; may not be null

subdivide

public void subdivide(int maxSubdivisionCount,
                      Consumer<ReplicaSets> subdivisionConsumer)

Subdivide this collection of replica sets into the maximum number of groups.

Parameters:

maxSubdivisionCount - the maximum number of subdivisions

subdivisionConsumer - the function to be called with each subdivision; may not be null

all

public List<ReplicaSet> all()

Get a copy of all of the ReplicaSet objects.

Returns:

the replica set objects; never null but possibly empty

validReplicaSets

public List<ReplicaSet> validReplicaSets()

Get a copy of all of the valid ReplicaSet objects that have names.

Returns:

the valid replica set objects; never null but possibly empty

unnamedReplicaSets

public List<ReplicaSet> unnamedReplicaSets()

Get a copy of all of the ReplicaSet objects that have no names.

Returns:

the unnamed replica set objects; never null but possibly empty

haveChangedSince

public boolean haveChangedSince(ReplicaSets priorState)

Determine if one or more replica sets has been added or removed since the prior state.

Parameters:

priorState - the prior state of the replica sets; may be null

Returns:

true if the replica sets have changed since the prior state, or false otherwise

hosts

public String hosts()

Get the string containing the host names for the replica sets. The result is a string with each replica set hosts separated by a semicolon.

Returns:

the host names; never null
