type Duration 

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

Duration naively implements the xsd:duration format defined by https://www.w3.org/TR/2004/REC-xmlschema-2-20041028/datatypes.html#duration N.B.: It is not intended to serve as a general xsd:duration as it does not implement the month side of xsd:duration.

func NewDuration 

func NewDuration(months int, d time.Duration) (Duration, error)

NewDuration returns an mpd.Duration corresponding to the length in months and time.Duration.

It returns an error if the sign of two arguments are different.

func (Duration) Add 

func (d Duration) Add(dur time.Duration) Duration

Add returns the mpd.Duration plus the given time.Duration.

func (Duration) AddToTime 

func (d Duration) AddToTime(t time.Time) time.Time

AddToTime returns the given time.Time plus the given mpd.Duration value..

func (Duration) Duration 

func (d Duration) Duration() (time.Duration, error)

Duration returns the mpd.Duration value as a time.Duration.

If Duration contains a non-zero value for the month side of the xsd:duration, then this function will return an error noting that the value is out of range..

func (Duration) MarshalXMLAttr 

func (d Duration) MarshalXMLAttr(name xml.Name) (xml.Attr, error)

MarshalXMLAttr implements xml.MarshalerAttr.

func (Duration) Scale 

func (d Duration) Scale(dur time.Duration) Duration

Scale returns the mpd.Duration scaled by the given time.Duration.

func (*Duration) UnmarshalXMLAttr 

func (d *Duration) UnmarshalXMLAttr(attr xml.Attr) error

UnmarshalXMLAttr implements xml.UnmarshalerAttr.

func (Duration) XMLString 

func (d Duration) XMLString() string

XMLString returns the XML representation of the Duration as a string.
