pynetdicom.pdu.A_ASSOCIATE_RJ¶

class pynetdicom.pdu.A_ASSOCIATE_RJ[source][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_length¶

The number of bytes from the first byte following the PDU Length field to the last byte of the PDU.

Type:	int

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 [1] (offsets shown with Python indexing). PDUs are always encoded using Big Endian [2].

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__()[source][source]¶: Initialise a new A-ASSOCIATE-RJ PDU.

Methods

`__init__`()	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 an 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.

decode(bytestream)[source]¶

Decode bytestream and use the result to set the field values of the PDU.

Parameters:	bytestream (bytes) – The PDU data to be decoded.

encode()[source]¶

Returns:	The encoded PDU.
Return type:	bytes

from_primitive(primitive)[source][source]¶

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

pdu_length: Return the PDU Length field value as an int.

pdu_type: Return the PDU Type field value an 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.

to_primitive()[source][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
