Constructor Detail

Topologies

public Topologies(TopologyDetails... details)

Create a new Topologies from a list of TopologyDetails.

Parameters:

details - the list of details to use.

Throws:

IllegalArgumentException - if duplicate topology ids are found.

Topologies

public Topologies(Map<String,TopologyDetails> topologies)

Create a new Topologies from a map of id to topology

Parameters:

topologies - a map of topology id to topology details.

Topologies

public Topologies(Topologies src)

Copy constructor.

Method Detail

getAllIds

public Collection<String> getAllIds()

getById

public TopologyDetails getById(String topologyId)

Get a topology given an ID

Parameters:

topologyId - the id of the topology to get

Returns:

the topology or null if it is not found.

getByName

public TopologyDetails getByName(String topologyName)

Get a topology given a topology name. Nimbus prevents multiple topologies from having the same name, so this assumes it is true.

Parameters:

topologyName - the name of the topology to look for

Returns:

the a topology with the given name.

getTopologies

public Collection<TopologyDetails> getTopologies()

getTopologiesOwnedBy

public Collection<TopologyDetails> getTopologiesOwnedBy(String user)

Get all topologies submitted/owned by a given user.

Parameters:

user - the name of the user

Returns:

all of the topologies submitted by this user.

toString

public String toString()

Overrides:

toString in class Object

iterator

public Iterator<TopologyDetails> iterator()

Specified by:

iterator in interface Iterable<TopologyDetails>
