Types

type ApplyDefaultAgencyFilter

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

ApplDefaultAgencyFilter sets a default agency_id value in relevant fields when the value is empty, e.g. routes.txt agency_id. It will only set a default agency_id value when the feed contains a single agency.

func (*ApplyDefaultAgencyFilter) Filter

func (e *ApplyDefaultAgencyFilter) Filter(ent tt.Entity, emap *tt.EntityMap) error

type ApplyParentTimezoneFilter

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

ApplyParentTimezoneFilter sets timezone based on the default agency timezone or parent stop timezone Can be used with NormalizeTimezoneFilter

func (*ApplyParentTimezoneFilter) Filter

func (e *ApplyParentTimezoneFilter) Filter(ent tt.Entity, emap *tt.EntityMap) error

type ApplyTimezoneFilter

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

ApplyTimezoneFilter sets all timezones in the file to the specified value

func NewApplyTimezoneFilter

func NewApplyTimezoneFilter(timezone string) (*ApplyTimezoneFilter, error)

func (*ApplyTimezoneFilter) Filter

func (e *ApplyTimezoneFilter) Filter(ent tt.Entity, emap *tt.EntityMap) error

type BasicRouteTypeFilter

type BasicRouteTypeFilter struct{}

BasicRouteTypeFilter checks for extended route_type's and converts to basic route_types.

func (*BasicRouteTypeFilter) Filter

func (e *BasicRouteTypeFilter) Filter(ent tt.Entity, emap *tt.EntityMap) error

Filter converts extended route_types to basic route_types.

type NormalizeTimezoneFilter

type NormalizeTimezoneFilter struct{}

NormalizeTimezoneFilter changes a timezone alias to a normalized timezone, e.g. "US/Pacific" -> "America/Los_Angeles"

func (*NormalizeTimezoneFilter) Filter

func (e *NormalizeTimezoneFilter) Filter(ent tt.Entity, emap *tt.EntityMap) error
