grapa.parse.curve_subclasses_utils.FileLoaderOnDemand

class grapa.parse.curve_subclasses_utils.FileLoaderOnDemand(filename, call_index=None)

Bases: object

A class to handle loading data from external files (e.g. configuration information, reference datasets), that we do not want to parse systematically at run-time, only once, on demand when actually needed. The instance can be called (), accessed by index [], and .get(“label abc”). Also, .labels() provide list of possible labels (or other key)

__init__(filename, call_index=None)

filename: file where data are located call_index: call on object instance will return Object[call_index]

Methods

__init__(filename[, call_index])	filename: file where data are located call_index: call on object instance will return Object[call_index]
get(value[, key])	Returns the first Curve with key==value
labels([key])	Returns the list of possible labels corresponding to each Curve in content

get(value, key='label')

Returns the first Curve with key==value

labels(key='label')

Returns the list of possible labels corresponding to each Curve in content
