| def | __new__ (mcs, name, bases, dct) |
A PClass is a python class with a fixed set of specified fields. PClasses are declared as python classes inheriting from PClass. It is defined the same way that PRecords are and behaves like a PRecord in all aspects except that it is not a PMap and hence not a collection but rather a plain Python object. More documentation and examples of PClass usage is available at https://github.com/tobgu/pyrsistent

| def create | ( | cls, | |
| kwargs, | |||
_factory_fields = None, |
|||
ignore_extra = False |
|||
| ) |
Factory method. Will create a new PClass of the current type and assign the values
specified in kwargs.
:param ignore_extra: A boolean which when set to True will ignore any keys which appear in kwargs that are not
in the set of fields on the PClass.
| def evolver | ( | self | ) |
Returns an evolver for this object.
| def remove | ( | self, | |
| name | |||
| ) |
Remove attribute given by name from the current instance. Raises AttributeError if the attribute doesn't exist.
| def serialize | ( | self, | |
format = None |
|||
| ) |
Serialize the current PClass using custom serializer functions for fields where such have been supplied.
Reimplemented from CheckedType.
| def set | ( | self, | |
| * | args, | ||
| ** | kwargs | ||
| ) |
Set a field in the instance. Returns a new instance with the updated value. The original instance remains
unmodified. Accepts key-value pairs or single string representing the field name and a value.
>>> from pyrsistent import PClass, field
>>> class AClass(PClass):
... x = field()
...
>>> a = AClass(x=1)
>>> a2 = a.set(x=2)
>>> a3 = a.set('x', 3)
>>> a
AClass(x=1)
>>> a2
AClass(x=2)
>>> a3
AClass(x=3)
| def transform | ( | self, | |
| * | transformations | ||
| ) |
Apply transformations to the currency PClass. For more details on transformations see the documentation for PMap. Transformations on PClasses do not support key matching since the PClass is not a collection. Apart from that the transformations available for other persistent types work as expected.
