An S4 class to represent model input

modInp class is used to store interpolated date for the model input parameters. It includes all the model sets, mappings, and parameters, interpolated to the scenario's calendar and horizon. The class is automatically created during the interpolation step and is not intended to be created by users.

Slots

sets

list. named list of character vectors with sets used in the model.

parameters

list. named list of parameter objects with three tipes - set: detailed description of the set - parameter: all model parameters, interpolated for every milestone year in the model horizon if applicable. Names of parameters start with 'p'

• mapping sets: auxiliary, automatically created sets used to narrow the dimension of variables and constraints

user_constraints

list. named list of user-defined constraints compiled from constraint objects: solver-agnostic equation code (GAMS-flavored intermediate representation) that each backend writer translates into its language. One entry per constraint.

user_costs

character. character vector of user cost terms compiled from costs objects, in the same solver-agnostic representation; the write step sums them into the eqTotalUserCosts equation of the objective.

misc

list. Any additional information or data to store in the object. Also used to store paths to the data files of objects stored on the disk.
