`PacketParser`

Static class for a parser that interprets packets representing data sent from the remote control app.

Inherits from: common.PacketParserBase

Members inherited from the base class are listed.

`is_valid()`

is_valid(bare_packet)

Checks whether the given raw packet is valid.

Arguments

Name	Type	Description
`bare_packet`	`common.BarePacket`	Raw packet data

Returns

Type	Value	Description
`bool`	`True`	Valid, parsable
	`False`	Invalid, not parsable

`parse()`

parse(bare_packet)

Parses the given raw packet.

Arguments

Name	Type	Description

Returns

Type	Value	Description
`optional ParsedPacket`	Data of type `ParsedPacket`	Parsed data
	`None`	Parsing failed

`ParsedPacket`

Data structure to store the result of interpreting packets representing data sent from the remote control app.

You can pass a dictionary unpacked with **.

In addition to the constructor arguments, the following @computed_field are available.

Name	Type	Description
`mwings_implementation`	`str`	MWings implementation (`"python"` only)
`mwings_version`	`str`	MWings version (PEP440 format)
`hostname`	`str`	Host machine name
`system_type`	`str`	System type (e.g., `"Linux"`)

Applicable field_validator

source_logical_id: Automatically validates the value range
- check_source_logical_id(lid)
time_parsed: Automatically validates that timezone is attached
- datetime_must_be_clear(dt)

Applicable field_serializer

packet_type: Serializes the enum name as is for JSON, etc.
- serialize_packet_type(packet_type)
source_serial_id: Serializes as a hexadecimal string for JSON, etc.
- serialize_source_serial_id(source_serial_id)
time_parsed: Serializes as ISO 8601 string for JSON, etc.
- serialize_time_parsed(dt)

`to_df()`

to_df(include=None, exclude=None, verbose=True)

Converts the parsed data to a pandas DataFrame.

Arguments

Name	Type	Description
`include`	`optional set[str]`	Set of columns (members) to include in the DataFrame
`exclude`	`optional set[str]`	Set of columns (members) to exclude from the DataFrame
`verbose`	`bool`	Include system information (only when other args are `None`)

Returns

Type	Value	Description
`pd.DataFrame`	-	Converted DataFrame

Exceptions

EnvironmentError if pandas is not installed

`to_dict()`

to_dict(include=None, exclude=None, verbose=True, spread=False, sort_keys=False)

Converts the parsed data to a dictionary.

Arguments

Name	Type	Description
`include`	`optional set[str]`	Set of keys (members) to include in the dictionary
`exclude`	`optional set[str]`	Set of keys (members) to exclude from the dictionary
`verbose`	`bool`	Include system information (only when other args are `None`)
`spread`	`bool`	Whether to split non-time-series list-like data
`sort_keys`	`bool`	Whether to sort keys

When spread is set, data of type common.CrossSectional[T] is split.

Returns

Type	Value	Description
`dict[str, Any]`	-	Converted dictionary

`to_json()`

to_json(include=None, exclude=None, verbose=True, spread=False, indent=2, sort_keys=False)

`exclude`	`optional set[str]`	Set of keys (members) to exclude from the JSON
`verbose`	`bool`	Include system information (only when other args are `None`)
`spread`	`bool`	Whether to split non-time-series list-like data
`indent`	`optional int`	Number of spaces for indentation (`None` for no newline)
