type Type interface {
	IsScalar() bool
}

Type interface is the wrapper interface for all types

func TypeForName 

func TypeForName(name string) (Type, bool)

TypeForName returns the type corresponding to the given name. If name is not recognized, it returns nil.

type TypeID 

type TypeID byte

TypeID is the id used to identify a type. 

const (
	BytesID    TypeID = 0
	Int32ID    TypeID = 1
	FloatID    TypeID = 2
	BoolID     TypeID = 3
	DateTimeID TypeID = 4
	StringID   TypeID = 5
	DateID     TypeID = 6
	GeoID      TypeID = 7
)

Note: These ids are stored in the posting lists to indicate the type of the data. The order *cannot* be changed without breaking existing data. When adding a new type *always* add to the end of this list. Never delete anything from this list even if it becomes unused.

type Value 

type Value interface {
	encoding.TextMarshaler
	encoding.TextUnmarshaler
	encoding.BinaryMarshaler
	encoding.BinaryUnmarshaler
	json.Marshaler
	// Type returns the type of this value
