pynetdicom.pdu.A_ASSOCIATE_RJ

class pynetdicom.pdu.A_ASSOCIATE_RJ(primitive: A_ASSOCIATE | None = None)

An A-ASSOCIATE-RJ PDU.

An A-ASSOCIATE-RJ PDU is sent by an association acceptor to indicate that association negotiation has been unsuccessful.

pdu_type

The PDU Type field value (0x03).

Type:

int

reason_diagnostic

The Reason/Diagnostic field value.

Type:

int

result

The Result field value.

Type:

int

source

The Source field value.

Type:

int

Notes

An A-ASSOCIATE-RJ PDU requires the following parameters:

• PDU type (1, fixed value, 0x03)

• PDU length (1)

• Result (1)

• Source (1)

• Reason/Diagnostic (1)

Encoding

When encoded, an A-ASSOCIATE-RJ PDU has the following structure, taken from Table 9-21 (offsets shown with Python indexing). PDUs are always encoded using Big Endian.

Offset	Length	Description
0	1	PDU type
1	1	Reserved
2	4	PDU length
6	1	Reserved
7	1	Result
8	1	Source
9	1	Reason/diagnostic

__init__(primitive: A_ASSOCIATE | None = None) → None

Initialise a new A-ASSOCIATE-RJ PDU.

Parameters:

primitive (pynetdicom.pdu_primitive.A_ASSOCIATE) – The primitive to use to initialise the PDU.

Methods

__init__([primitive])	Initialise a new A-ASSOCIATE-RJ PDU.
decode(bytestream)	Decode bytestream and use the result to set the field values of the PDU.
encode()	Return the encoded PDU as bytes.
from_primitive(primitive)	Setup the current PDU using an A-ASSOCIATE (reject) primitive.
to_primitive()	Return an A-ASSOCIATE (reject) primitive from the current PDU.

Attributes

pdu_length	Return the PDU Length field value as an int.
pdu_type	Return the PDU Type field value as int.
reason_str	Return a str describing the Reason/Diagnostic field value.
result_str	Return a str describing the Result field value.
source_str	Return a str describing the Source field value.

from_primitive(primitive: A_ASSOCIATE) → None

Setup the current PDU using an A-ASSOCIATE (reject) primitive.

Parameters:

primitive (pdu_primitives.A_ASSOCIATE) – The primitive to use to set the current PDU field values.

property pdu_length: int

Return the PDU Length field value as an int.

property reason_str: str

Return a str describing the Reason/Diagnostic field value.

property result_str: str

Return a str describing the Result field value.

property source_str: str

Return a str describing the Source field value.

to_primitive() → A_ASSOCIATE

Return an A-ASSOCIATE (reject) primitive from the current PDU.

Returns:

The primitive representation of the current PDU.

Return type:

pdu_primitives.A_ASSOCIATE
