idf_object {eplusr}R Documentation

Create an IdfObject object.


idf_object() takes a parent Idf object, an object name or class name, and returns a corresponding IdfObject.


idf_object(parent, object = NULL, class = NULL)



An Idf object.


A valid object ID (an integer) or name (a string). If NULL and class is not NULL, an empty IdfObject is created with all fields fill with default values if possible. Default: NULL.


A valid class name (a string). If object is not NULL, class is used to further specify what class is the target object belongs to. If object is NULL, an empty IdfObject of class is created.


If object is not given, an empty IdfObject of specified class is created, with all field values filled with defaults, if possible. Note that validation is performed when creating, which means that an error may occur if current validate level does not allow empty required fields.

The empty IdfObject is directly added into the parent Idf object. It is recommended to use ⁠$validate()⁠ method in IdfObject to see what kinds of further modifications are needed for those empty fields and use ⁠$set()⁠ method to set field values.


An IdfObject object.

# different class
