Preparer handles querying

func (*Preparer) Prepare

func (p *Preparer) Prepare(render resource.Renderer) (resource.Task, error)

Prepare creates a new query type

type Query

type Query struct {
	*shell.Shell
}

Query represents an environmental query

func (*Query) Apply

func (q *Query) Apply() (resource.TaskStatus, error)

Apply is a nop for queries. Because HasChanges always returns false this should never be executed.

func (*Query) HasChanges

func (q *Query) HasChanges() bool

HasChanges returns true if changes are required as determined by the the most recent run of check.

func (*Query) Messages

func (q *Query) Messages() (messages []string)

Messages returns a summary of the first execution of check and/or apply. Subsequent runs are surpressed.
