ait.core.evr module

AIT Event Record (EVR) Reader

The ait.core.evr module is used to read the EVRs from a YAML file.

class ait.core.evr.EVRDefn(*args, **kwargs)

Bases: ait.core.json.SlotSerializer, object

__init__(*args, **kwargs)

Creates a new EVR Definition.

format_message(evr_hist_data)

Format EVR message with EVR data

Given a byte array of EVR data, format the EVR’s message attribute printf format strings and split the byte array into appropriately sized chunks. Supports most format strings containing length and type fields.

Args:

evr_hist_data: A bytearray of EVR data. Bytes are expected to be in

MSB ordering.

Example formatting:

# This is the character '!', string 'Foo', and int '4279317316'
bytearray([0x21, 0x46, 0x6f, 0x6f, 0x00, 0xff, 0x11, 0x33, 0x44])

Returns:

The EVR’s message string formatted with the EVR data or the unformatted EVR message string if there are no valid format strings present in it.

Raises:

ValueError: When the bytearray cannot be fully processed with the

specified format strings. This is usually a result of the expected data length and the byte array length not matching.
