type Value

type Value interface {
	fmt.Stringer
	Comparable

	// AsInterface to return the value as interface
	AsInterface() interface{}
}

Value is our value object that implements comparable so that two values can be compared. This is used to build the keys(primary key or any other index key), or to build the selector filter. Note: if the field data type is byte/binary then the value object returned is base64 decoded. The reason is that JSON has encoded the byte array to base64 so to make sure we are using the user provided value in building the key and the filter we must first decode this field. This allows us later to perform prefix scans.

func NewValue

func NewValue(fieldType schema.FieldType, value []byte) (Value, error)

NewValue returns the value of the field from the raw json value. It uses schema to get the type of the field.

func NewValueUsingCollation

func NewValueUsingCollation(fieldType schema.FieldType, value []byte, collation *api.Collation) (Value, error)
