lisa.wlgen.rta.AndProperty#

class lisa.wlgen.rta.AndProperty[source]#

Bases: PropertyBase

Semigroup property with the & operation.

Classes

Metaclass for properties.

Attributes

Subclasses can override this attribute so that PropertyBase.from_key() knows that it can call their _from_key() method for that key.

Properties

`key` ^inherited	Key of the instance.
`val` ^inherited	Value “payload” of the property.

Methods

`__and__()`	Combine values of the properties using `_SEMIGROUP_OP()`, except when one of the value is `None`, in which case the other value is used as is and wrapped into an instance using `from_key()`.
`HASH_COERCE()` ^inherited	Used to coerce the values of `self.__dict__` to hashable values.
`find_cls()` ^inherited	Find which subclass can handle `key`.
`from_key()` ^inherited	Alternative constructor that is available with the same signature for all properties.

Classes#

AndProperty.KEY = None#: Subclasses can override this attribute so that PropertyBase.from_key() knows that it can call their _from_key() method for that key.

Note

This class attribute will not be inherited automatically so that each class can be uniquely identified by its key. Subclass that do not override the value explicitly will get None.

property AndProperty.key#

Inherited property, see lisa.wlgen.rta.PropertyBase.key

Key of the instance.

abstract property AndProperty.val#

Inherited property, see lisa.wlgen.rta.PropertyBase.val

Value “payload” of the property.

AndProperty.__and__(other)#: Combine values of the properties using _SEMIGROUP_OP(), except when one of the value is None, in which case the other value is used as is and wrapped into an instance using from_key().

AndProperty.HASH_COERCE(x, coerce)#

Used to coerce the values of self.__dict__ to hashable values.

classmethod AndProperty.find_cls(key)#

Find which subclass can handle key.

classmethod AndProperty.from_key(key, val)#

Alternative constructor that is available with the same signature for all properties.
