class tiled.trees.in_memory.Tree(mapping, metadata=None, access_policy=None, authenticated_identity=None, entries_stale_after=None, metadata_stale_after=None, must_revalidate=True)

A Tree backed by a mapping.

__init__(mapping, metadata=None, access_policy=None, authenticated_identity=None, entries_stale_after=None, metadata_stale_after=None, must_revalidate=True)

Create a simple Tree from any mapping (e.g. dict, OneShotCachedMap).

Parameters

entries_stale_after: timedelta

This server uses this to communite to the client how long it should rely on a local cache before checking back for changes.

metadata_stale_after: timedelta

This server uses this to communite to the client how long it should rely on a local cache before checking back for changes.

must_revalidatebool

Whether the client should strictly refresh stale cache items.

Methods

__init__(mapping[, metadata, access_policy, ...])	Create a simple Tree from any mapping (e.g.
authenticated_as(identity)
get(k[,d])
items()
keys()
new_variation(*args[, mapping, metadata, ...])
register_query(class_, translator)
register_query_lazy(toplevel, register)	Register a registration function which will be called if the toplevel module (e.g.
search(query)	Return a Tree with a subset of the mapping.
