Makes use of the socket library.
- class Tcp(configuration)[source]
Bases:
CommunicationProtocol
Tcp Communication Protocol.
- static config_cls() type[hvl_ccb.comm.tcp.TcpCommunicationConfig] [source]
Return the default configdataclass class.
- Returns:
a reference to the default configdataclass class
- class TcpCommunicationConfig(host: str | IPv4Address | IPv6Address, port: int = 54321, bufsize: int = 1024)[source]
Bases:
object
Configuration dataclass for
TcpCommunication
.- bufsize: int = 1024
- force_value(fieldname, value)
Forces a value to a dataclass field despite the class being frozen.
NOTE: you can define post_force_value method with same signature as this method to do extra processing after value has been forced on fieldname.
- Parameters:
fieldname – name of the field
value – value to assign
- host: str | IPv4Address | IPv6Address
- is_configdataclass = True
- classmethod keys() Sequence[str]
Returns a list of all configdataclass fields key-names.
- Returns:
a list of strings containing all keys.
- classmethod optional_defaults() dict[str, object]
Returns a list of all configdataclass fields, that have a default value assigned and may be optionally specified on instantiation.
- Returns:
a list of strings containing all optional keys.
- port: int = 54321
- classmethod required_keys() Sequence[str]
Returns a list of all configdataclass fields, that have no default value assigned and need to be specified on instantiation.
- Returns:
a list of strings containing all required keys.
