RelayBoolGate

Defined in module: wield.declarative.callbacks.state_booleans.RelayBoolGate

class RelayBoolGate(*args, **kwargs)

Bases: RelayBoolBase, ReprMixin

Base class to implement the logic needed for syncronous action of logic gates of RelayBools.

These gates are all based on monitoring sub-bools using a count. Subclasses set the values of

__init__(relay_bools=(), **kwargs)

Parameters:

relay_bools – iterable of Relays Bools to set up initial gate value

Methods

__init__([relay_bools])
bool_register(relay_bool[, name, remove])
bool_unregister(relay_bool[, name])
register([key, callback, assumed_value, ...])	Register a function for callback when this bool's state changes.
register_via(reg_call, callback[, key, remove])

Attributes

monitored_bools_count
monitored_bools
callbacks_ontoggle
is_set	Returns T/F status of the bool

bool_unregister(relay_bool, name=None)

register(key=None, callback=None, assumed_value=('<UNIQUE VALUE>', <function unique_generator.<locals>.UNIQUE_CLOSURE>), call_immediate=False, remove=False)

Register a function for callback when this bool’s state changes.

Parameters:

• callback – function to register

• call_immediate – call as the function is added

• remove – (False) set to remove a callback

Raises:

KeyError on missing callback

The function should have the signature

callback(bool_state):

Parameters:

bool_state – state of the RelayBool’s new value

callbacks_ontoggle

property is_set

Returns T/F status of the bool
