Types ¶

type Status ¶

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

Status holds a handle to the database where the status can be queried

func NewStatus ¶

func NewStatus(db *sql.DB) *Status

NewStatus returns a *Status structure to the user

func (*Status) Get ¶

func (status *Status) Get(name string) int

Get returns the value of the variable name requested (if found), or if not an error - note: we assume we have checked a variable first as there's no logic here to switch between I_S and P_S

type Variables ¶

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

Variables holds the handle and variables collected from the database

func NewVariables ¶

func NewVariables(db *sql.DB) *Variables

NewVariables returns a pointer to an initialised Variables structure with one collection done.

func (Variables) Get ¶

func (v Variables) Get(key string) string

Get returns the value of the given variable if found or an empty string if not.
