Functions

func Graft added in v0.17.0 

func Graft(root *yaml.Node, path string, toAdd []byte, graftedName string) (out []byte, err error)

Graft takes a root node, a path to a role in root, byte array with an existing role and appends this role asa child of the role in root where the path specifies.

func LeafWalk added in v0.20.2 

func LeafWalk(root Role, do func(role Role))

func LoadWorkflow added in v0.17.0 

func LoadWorkflow(in []byte) (out yaml.Node, err error)

func RoleToYAML added in v0.17.0 

func RoleToYAML(input Role) ([]byte, error)

RoleToYAML exists to avoid exporting aggregatorRole/iteratorRole. Simply put, this function is nothing but a wrapper which allows marshalling Roles outside the workflow package

func Walk added in v0.20.2 

func Walk(root Role, do func(role Role))

func WrapConstraints added in v0.19.90 

func WrapConstraints(items constraint.Constraints) template.Fields
