pynetdicom.pdu.A_ASSOCIATE_RJ¶

class pynetdicom.pdu.A_ASSOCIATE_RJ(primitive: Optional[A_ASSOCIATE] = None)[source]¶

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: Optional[A_ASSOCIATE] = None) → None[source]¶

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[source]¶

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[source]¶

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

Returns: The primitive representation of the current PDU.
Return type: pdu_primitives.A_ASSOCIATE
