LabelMapping

core.mapping.LabelMapping(name_to_label=None)

A simplified label mapping class that provides bidirectional mapping functionality.

This class maintains two mappings: 1. Forward mapping (name -> label): Maps semantic names to label values. 2. Reverse mapping (label -> name): Maps label values back to semantic names.

The mapping ensures uniqueness of both names and labels.

Methods

Name	Description
from_json	Initialize a label mapping from a JSON string.
has_label	Check if a label exists in the mapping.
inverse	Get semantic name by label value (reverse mapping).
items	Get an iterator of name-label pairs.
to_json	Convert the mapping to a JSON string.

from_json

core.mapping.LabelMapping.from_json(json_str)

Initialize a label mapping from a JSON string.

Args: json_str: JSON string representation of the mapping.

Returns: LabelMapping: A new instance initialized with data from JSON.

has_label

core.mapping.LabelMapping.has_label(label)

Check if a label exists in the mapping.

Args: label: Label value to check.

Returns: bool: True if the label exists, False otherwise.

inverse

core.mapping.LabelMapping.inverse(label)

Get semantic name by label value (reverse mapping).

Args: label: Label value.

Returns: str: Corresponding semantic name.

Raises: KeyError: If label is not found in the mapping.

items

core.mapping.LabelMapping.items()

Get an iterator of name-label pairs.

Returns: Iterator[Tuple[str, int]]: Iterator of (name, label) pairs.

to_json

core.mapping.LabelMapping.to_json()

Convert the mapping to a JSON string.

Returns: str: JSON string representation of the mapping.
