py2store.utils.mappify

Utils to wrap any object into a mapping interface

Functions

bracket_getter(obj, k)
dot_str_key_iterator(p)
simple_glom(target, spec[, node_types, ...])

Classes

LeafMappify(target[, node_types, ...])	A dict-like interface to glom.
Mappify(target[, node_types, key_concat, ...])

class py2store.utils.mappify.LeafMappify(target, node_types=(<class 'dict'>, ), key_concat=<function Mappify.<lambda>>, names_of_literals=(), **kwargs)

Bases: Mappify

A dict-like interface to glom. Here, only leaf keys are taken into account.
