Types ¶

type GAPI ¶

type GAPI struct {
	// contains filtered or unexported fields
}

GAPI implements the main langpuppet GAPI interface. It wraps the Puppet and Lang GAPIs and receives graphs from both. It then runs a merging algorithm that mainly just makes a union of both the sets of vertices and edges. Some vertices are merged using a naming convention. Details can be found in the langpuppet.mergeGraphs function.

func (*GAPI) Cli ¶

func (obj *GAPI) Cli(info *gapi.Info) (*gapi.Deploy, error)

Cli takes an *Info struct, and returns our deploy if activated, and if there are any validation problems, you should return an error. If there is no deploy, then you should return a nil deploy and a nil error.

func (*GAPI) Close ¶

func (obj *GAPI) Close() error

Close shuts down the Puppet GAPI.

func (*GAPI) Graph ¶

func (obj *GAPI) Graph() (*pgraph.Graph, error)

Graph returns a current Graph.

func (*GAPI) Info ¶

func (obj *GAPI) Info() *gapi.InfoResult

Info returns some data about the GAPI implementation.

func (*GAPI) Init ¶

func (obj *GAPI) Init(data *gapi.Data) error

Init initializes the langpuppet GAPI struct.

func (*GAPI) Next ¶

func (obj *GAPI) Next() chan gapi.Next

Next returns nil errors every time there could be a new graph.
