Types

type Interface 

type Interface interface {
	Resolve(
		c component.Interface,
		id v1.SystemID,
		path tree.Path,
		ctx *git.CommitReference,
		depth int,
	) (*ResolutionTree, error)
	Versions(component.Interface, semver.Range) ([]string, error)
}

func NewComponentResolver 

func NewComponentResolver(
	gitResolver *git.Resolver,
	templateStore TemplateStore,
	secretStore SecretStore,
) Interface

type ResolutionInfo 

type ResolutionInfo struct {
	// Component contains the hydrated but unresolved version of the component.
	// That is, if the component is a v1/system, it may contain unresolved references.
	Component component.Interface
	Commit    *git.CommitReference
	// TODO(kevindrosendahl): probably want to move this out when we have a more
	// concrete theory on component resolution secrets.
	SSHKeySecret *tree.PathSubcomponent
}

ResolutionInfo contains information about the resolution of a subcomponent.

type ResolutionTree 

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

ResolutionTree provides efficient path-based access to info about the resolution of a given tree of components.

func NewResolutionTree 

func NewResolutionTree() *ResolutionTree

NewResolutionTree returns an initialized ResolutionTree.

func (*ResolutionTree) Delete 

func (t *ResolutionTree) Delete(p tree.Path) (*ResolutionInfo, bool)

func (*ResolutionTree) UnmarshalJSON 

func (t *ResolutionTree) UnmarshalJSON(data []byte) error

MarshalJSON fulfills the json.Unmarshaller interface.

func (*ResolutionTree) V1 

func (t *ResolutionTree) V1() *V1Tree

V1 returns a V1 tree allowing retrieval of v1 components in the tree.
