Makes pdu be reply to the reply_to_pdu, i.e. assigns reply_to_pdu's sequence_number to pdu.

Checks if Pdu is a bind request.

Checks if Pdu is a bind response.

Returns Pdu's command_id.

Returns Pdu's symbolic command name as an atom or :unknown if Pdu's command_id do not correspond to any real SMPP command.

Returns Pdu's command_status.

Returns Pdu's :destination_addr, :dest_addr_ton and :dest_addr_npi fields in a tuple.

Get Pdu mandatory or optional(TLV) field by name or by integer id. If Pdu does not have the field or field name is unknown, nil is returned.

Get the whole set of mandatory fields as a map.

Construct a new Pdu from header, mandatory fields and optional(TLV) fields.

Get Pdu optional(TLV) field by name or by integer id. If Pdu does not have the field or field name is unknown, nil is returned.

Get the whole set of optional(TLV) fields as a map.

Returns Pdu's unique reference ref.

Checks if Pdu is a response Pdu.

Checks if two Pdus are copies of the same Pdu.

Returns Pdu's sequence_number.

Sets Pdu mandatory field. New Pdu is returned.

Sets Pdu optional field. New Pdu is returned.

View Source
@spec new(header(), map(), map()) :: t()

Header may be either an integer, then it is treated as command id, or a tuple {command_id, command_status, sequence_number}

Each Pdu is created with a unique ref field, by which one can later trace Pdu's identity.
