DefaultGraphDescription

public DefaultGraphDescription(long nanos,
                               long millis,
                               java.lang.Iterable<Device> devices,
                               java.lang.Iterable<Link> links,
                               SparseAnnotations... annotations)

Creates a minimal topology graph description to allow core to construct and process the topology graph.

Parameters:

nanos - time in nanos of when the topology description was created

millis - time in millis of when the topology description was created

devices - collection of infrastructure devices

links - collection of infrastructure links

annotations - optional key/value annotations map

Method Detail

timestamp

public long timestamp()

Description copied from interface: GraphDescription

Returns the creation timestamp of the graph description. This is expressed in system nanos to allow proper sequencing.

Specified by:

timestamp in interface GraphDescription

Returns:

graph description creation timestamp

creationTime

public long creationTime()

Description copied from interface: GraphDescription

Returns the creation timestamp of the graph description. This is expressed in system millis to allow proper date and time formatting.

Specified by:

creationTime in interface GraphDescription

Returns:

graph description creation timestamp in millis

vertexes

public com.google.common.collect.ImmutableSet<TopologyVertex> vertexes()

Description copied from interface: GraphDescription

Returns the set of topology graph vertexes.

Specified by:

vertexes in interface GraphDescription

Returns:

set of graph vertexes

edges

public com.google.common.collect.ImmutableSet<TopologyEdge> edges()

Description copied from interface: GraphDescription

Returns the set of topology graph edges.

Specified by:

edges in interface GraphDescription

Returns:

set of graph edges
