Loading from and Writing into Storage

One can also omit the arguments in the constructor and load the specification from a storage, using the method load(). It takes the following arguments:

resources

- an object of class Resources. If the remaining arguments are given, they will have priority over entries of the same name in resources.

in_storage

- an object of class Storage that overwrites the one given in the constructor.

in_table_name

- name of the table/file where the specification should be loaded from.

variables

- if this argument is given, it serves as a filter for the variables loaded from the store.

For each of the class properties variables, coefficients, equations, and submodels, respectively, a table column is expected on the storage. The column names are given in the resources entries field_variable_name, field_coefficient_name, field_equation_id, and field_submodel_id, respectively. Default values are 'variable_name, 'coefficient_name, 'equation_id, and 'sub_model_id.

The variables and coefficients are stored in the class attributes variables and coefficients. Equations and submodels are stored only if their maximum value is not negative.

To store a specification into a storage, use the method write(resources, out_storage, out_table_name). The behavior is analogous to the load() method. If equations or/and submodels are not used, the method stores values $-2$ in those columns.
