pynetdicom.pdu.A_ABORT_RQ

class pynetdicom.pdu.A_ABORT_RQ

An A-ABORT-RQ PDU.

An A-ABORT-RQ PDU is used to abort the association.

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 (0x07).

Type

int

reason_diagnostic

The Reason/Diagnostic field value.

Type

int

source

The Source field value.

Type

int

Notes

An A-ABORT-RQ PDU requires the following parameters:

• PDU type (1, fixed value, 0x06)

• PDU length (1, fixed value, 4)

• Source (1)

• Reason/Diagnostic (1)

Encoding

When encoded, an A-ABORT-RQ PDU has the following structure, taken from Table 9-26 (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	Reserved
8	1	Source
9	1	Reason/Diagnostic

__init__()

Initialise a new A-ABORT-RQ PDU.

Methods

__init__()	Initialise a new A-ABORT-RQ 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-ABORT or A-P-ABORT primitive.
to_primitive()	Return an A-ABORT or A-P-ABORT 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 description of the Reason/Diagnostic field value.
source_str	Return a str description of the Source field value.

from_primitive(primitive)

Setup the current PDU using an A-ABORT or A-P-ABORT primitive.

Parameters

primitive (pdu_primitives.A_ABORT or pdu_primitives.A_P_ABORT) – The primitive to use to set the current PDU field values.

property pdu_length

Return the PDU Length field value as an int.

property reason_str

Return a str description of the Reason/Diagnostic field value.

property source_str

Return a str description of the Source field value.

to_primitive()

Return an A-ABORT or A-P-ABORT primitive from the current PDU.

Returns

The primitive representation of the current PDU.

Return type

pdu_primitives.A_ABORT or pdu_primitives.A_P_ABORT
