Types

type Body

type Body interface {
	Len() int
	Raw() interface{}
	String() string
	Bytes() []byte
	SerializeTo(w io.Writer) error
}

Body is an interface for manipulating binary PDU Tag-Length-Value field data.

func NewTLV

func NewTLV(tag Tag, value []byte) Body

NewTLV parses the given binary data and returns a Data object, or nil if the field Name is unknown.

type CString

type CString string

CString is a text string that is automatically null-terminated (e.g., final 00 byte at the end).

type Field

type Field struct {
	Tag  Tag
	Data []byte
}

Field is a PDU Tag-Length-Value (TLV) field

func (*Field) Bytes

func (t *Field) Bytes() []byte

Bytes implements the Data interface.

func (*Field) Len

func (t *Field) Len() int

Len implements the Data interface.

func (*Field) Raw

func (t *Field) Raw() interface{}

Raw implements the Data interface.

func (*Field) SerializeTo

func (t *Field) SerializeTo(w io.Writer) error

SerializeTo implements the Data interface.

func (*Field) String

func (t *Field) String() string

String implements the Data interface.

type Fields

type Fields map[Tag]interface{}

Fields is a map of tagged TLV fields

type Map

type Map map[Tag]Body

Map is a collection of PDU TLV field data indexed by tag.

func DecodeTLV

func DecodeTLV(r *bytes.Buffer) (Map, error)

DecodeTLV scans the given byte slice to build a Map from binary data.

func (Map) MarshalJSON

func (m Map) MarshalJSON() ([]byte, error)

func (Map) Set

func (m Map) Set(t Tag, v interface{}) error

Set updates the PDU map with the given tag and value, and returns error if the value cannot be converted to type Data.

This is a shortcut for m[t] = NewTLV(t, v) converting v properly.

func (*Map) UnmarshalJSON

func (m *Map) UnmarshalJSON(b []byte) error

type MessageStateType

type MessageStateType uint8

const (
	Enroute       MessageStateType = 1 // The message is in enroute
	Delivered     MessageStateType = 2 // Message is delivered
	Expired       MessageStateType = 3 // Message validity period has expired
	Deleted       MessageStateType = 4 // Message has been deleted
	Undeliverable MessageStateType = 5 // Message is undeliverable
	Accepted      MessageStateType = 6 // Message is in accepted state
	Unknown       MessageStateType = 7 // Message is in invalid state
	Rejected      MessageStateType = 8 // Message is in a rejected state
)

func (MessageStateType) String

func (m MessageStateType) String() string

type String

type String string

String is a text string that is not null-terminated.

type Tag

type Tag uint16

Tag is the tag of a Tag-Length-Value (TLV) field.
