We consider addresses to be self-complete "labels" for locations.
It does not depend on any people actually living there. Thus
an address can get attached to as many people as we want to

This class acts on the address as an entity. Therefore it can
modify the address fields. Think carefully about *modifying*
addresses attached to people, though. Most times when you think
person.modify_address() what you *really* want is as sequence of
person.unlink_address(old) and person.link_address(new).
Modifying an address may or may not be the proper thing to do as
it will transparently modify the address for *all* the people to
whom it is attached. In many cases you will want to create a *new*
address and link it to a person instead of the old address.

Classes
class cAddress (aPK_obj: int | dict = None, row: dict = None, link_obj=None)-
A class representing an address as an entity in itself.
We consider addresses to be self-complete "labels" for locations. It does not depend on any people actually living there. Thus an address can get attached to as many people as we want to signify that that is their place of residence/work/…
This class acts on the address as an entity. Therefore it can modify the address fields. Think carefully about modifying addresses attached to people, though. Most times when you think person.modify_address() what you really want is as sequence of person.unlink_address(old) and person.link_address(new).
Modifying an address may or may not be the proper thing to do as it will transparently modify the address for all the people to whom it is attached. In many cases you will want to create a new address and link it to a person instead of the old address.
Call init from child classes like so:
super().__init__(aPK_obj = aPK_obj, row = row, link_obj = link_obj)Args
aPK_obj- retrieve data from backend
- a simple value the primary key WHERE condition must be a simple column
- a dictionary of values the primary key WHERE condition must be a subselect consuming the dict and producing the single-value primary key
row- must hold the fields
- idx: a dict mapping field names to position
- data: the field values in a list (as returned by cursor.fetchone() in the DB-API)
- pk_field: the name of the primary key field OR
- pk_obj: a dictionary suitable for passed to cursor.execute and holding the primary key values, used for composite PKs
- for example:

aPK_obj- retrieve data from backend
- a simple value the primary key WHERE condition must be a simple column
- a dictionary of values the primary key WHERE condition must be a subselect consuming the dict and producing the single-value primary key
row- must hold the fields
- idx: a dict mapping field names to position
- data: the field values in a list (as returned by cursor.fetchone() in the DB-API)
- pk_field: the name of the primary key field OR
- pk_obj: a dictionary suitable for passed to cursor.execute and holding the primary key values, used for composite PKs
- for example:

class cPersonTag (aPK_obj: int | dict = None, row: dict = None, link_obj=None)-
Represents business objects in the database.
Rules
- instances ARE ASSUMED TO EXIST in the database
- PK construction (aPK_obj): DOES verify its existence on instantiation (fetching data fails)
- Row construction (row): allowed by using a dict of pairs of field name: field value (PERFORMANCE improvement)
- does NOT verify FK target existence
- does NOT create new entries in the database
- does NOT lazy-fetch fields on access
Class scope SQL commands and variables:
_cmd_fetch_payload:
- must return exactly one row
- WHERE clause argument values are expected in self.pk_obj (taken from init(aPK_obj))
- must return xmin of all rows that _cmds_store_payload will be updating, so views must support the xmin columns of their underlying tables
_cmds_store_payload:
- one or multiple "update … set … where xmin_ = … and pk = …" statements which actually update the database from the data in self._payload,
- the last query must refetch at least the XMIN values needed to detect concurrent updates, their field names had better be the same as in _cmd_fetch_payload,
- the last query CAN return other fields which is particularly useful when those other fields are computed in the backend and may thus change upon save but will not have been set by the client code explicitly - this is only really of concern if the saved subclass is to be reused after saving rather than re-instantiated
- when subclasses tend to live a while after save_payload() was called and they support computed fields (say, _(some_column) you need to return all columns (see cEncounter)
