GeoEco.Datasets.Dataset

class GeoEco.Datasets.Dataset(parentCollection=None, queryableAttributes=None, queryableAttributeValues=None, lazyPropertyValues=None)

Bases: CollectibleObject

Base class for objects representing tabular and gridded datasets, principally Table and Grid.

Dataset is a base class that should not be instantiated directly; instead, users should instantiate one of the many derived classes representing the type of dataset they’re interested in.

Parameters:

• parentCollection (DatasetCollection, optional) – Parent DatasetCollection that this object is part of (if any).

• queryableAttributes (tuple of QueryableAttribute, optional) – Queryable attributes defined for this object.

• queryableAttributeValues (dict mapping str to object, optional) – Values of the queryable attributes, expressed as a dictionary mapping the case-insensitive names of queryable attributes to their values.

• lazyPropertyValues (dict mapping str to object, optional) – Lazy properties to set when this object is constructed, expressed as a dictionary mapping the names of lazy properties to their values.

Returns:

CollectibleObject instance.

Return type:

CollectibleObject

Properties

property DisplayName

(str) Informal name of this object, suitable to be displayed to the user. Read only. Minimum length꞉ 1.

property ParentCollection

(DatasetCollection or None) Parent DatasetCollection that this object is part of (if any). Read only.
