Functions

func AddMetadata

func AddMetadata(g *graph.Graph, id, key string, value interface{}) error

AddMetadata will insert metadata into the graph at the provided node. It returns an error if the id doesn't exist or the metadata key does.

func DependsOn

func DependsOn(g *graph.Graph, source, target string) bool

DependsOn returns true if target and source both exist in the graph, and there is a direct or transative dependency on target from source.
