Predefined task generators are stored in the mlr3misc::Dictionary mlr_task_generators,
e.g. xor.
R6::R6Class object.
g = TaskGenerator$new(id, task_type, packages = character(), param_set = ParamSet$new(), man = NA_character_)
id :: character(1)
Identifier for the learner.
task_type :: character(1)
Type of the task the learner can operator on. E.g., "classif" or "regr".
packages :: character()

All variables passed to the constructor, and additionally:
task_type :: character(1)

A complete list of task types is stored in mlr_reflections$task_types$type.
