ObjectStorage.RdR6Class for storing similar R6 objects. These objects all need to implement the method get_id() and get_name(). The id of an object is unique in a storage whereas multiple objects can share the same name.
storage = ObjectStorage$new(allowed_classes = NULL) storage$add_object(object) storage$get_object(id)
new(allowed_classes = NULL)Initialize the storage.
allowed_classes | Character vector. class(object) has to
return at least one of these classes for being added to the storage. |
add_object(object)Add an object to the storage:
object | R6 object with public methods get_id(),
and get_name(). |
get_ids()Get the ids of the stored objects as a character vector named with the object's names.
get_length()Get the length of the storage.
get_names()Get the objects' names, which aren't necessarily
unique. See also this$get_ids().
get_nth_object(n)Get the object with index n going
from 1 to this$get_length().
get_object(id)Get an object from the storage
with object$get_id() == id.
id | id of an R6 object. |
get_objects(ids)Get a list of objects from the storage
with object$get_id() %in% ids. If ids is missing get
a list with all objects.
ids | Character vector. Each element has to be a id of an object in the storage. |
remove_object(id)Remove an object with id == id.
remove_objects(ids)Remove objects with id %in% ids.
