Read-only dictionary-like interface to user-named heparchy datasets.

Parameters¶

reader : HdfProcessReader | HdfEventReader

The reader instance to which the MapReader will be attached.

iter_func : callable

The strategy used to iterate through the keys for the MapReader interface.

Raises¶

ReadOnlyError – Dictionary-like behaviour which requires write-access for datasets, as access to the data is strictly read-only.

Notes

This is a concrete subclass of collections.abc.MutableMapping, and thus includes all functionality expected of a dictionary, including iteration over keys and values, subscriptable access to datasets, etc.

Public members¶

MapReader(reader: HdfEventReader | HdfProcessReader, ...)[source]

Initialize self. See help(type(self)) for accurate signature.

__repr__() → str[source]

Return repr(self).

__getitem__(name: str) → MapValue[source]

__setitem__(name: str, data: MapValue)[source]

MapReader[params][source]

classmethod __init_subclass__(*args, **kwargs)[source]

This method is called when a class is subclassed.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.[source]

keys() → a set-like object providing a view on D's keys[source]

items() → a set-like object providing a view on D's items[source]

values() → an object providing a view on D's values[source]

__eq__(other)[source]

Return self==value.

classmethod __subclasshook__(C)[source]

Abstract classes can override this to customize issubclass().
