py3dtiles.tilers.point.node.shared_node_store module

class py3dtiles.tilers.point.node.shared_node_store.SharedNodeStore(folder: Path)

Bases: object

A class that implements a compressed storage for arbitrary data, that is able to limit the amount of ram it uses by temporary storing part of the storage on disk for later retrieval.

The memory limit is not automatic at the moment, but instead is done by calling self.control_memory_usage.

control_memory_usage(max_size_mb: int, verbose: int) → None

Limit the memory usage of this instance.

get(name: bytes, stat_inc: int = 1) → bytes

Get a node storage.

Parameters:

name – the name of the node

print_statistics() → None

put(name: bytes, data: bytes) → None

Insert or change

remove(name: bytes) → None

Remove a node from this storage.

remove_oldest_nodes(percent: float = 100) → Tuple[int, int]
