Functions

func Apply

func Apply(flt Filter, in []geodb.Location, out []geodb.Location) int

* Apply a filter to a set of geographical locations to narrow it down.

func Evaluate

func Evaluate(flt Filter, locs []geodb.Location, result []bool)

* Evaluate whether a set of geographical locations matches filter criteria.

func ParseTime

func ParseTime(timestamp string, sloppy bool, utc bool) (time.Time, error)

* Creates a UTC time stamp from RFC3339 string representation.

Types

type Filter

type Filter interface {
	Evaluate(loc *geodb.Location) bool
}

* A filter for location data.

func Time

func Time(min time.Time, max time.Time) Filter

* Creates a filter which matches data points in a given time interval. * * Time values may be zero to leave either or both of the bounds open.
