This class is responsible for managing the callbacks and holding the tree structure of an estimator's tasks. Each instance corresponds to a task of the estimator. This class should not be instantiated directly, but through the `_init_callback_context` method of the estimator to create the root context or using the `subcontext` method of this class to create sub-contexts. These contexts are passed to the callback hooks to be able to keep track of the position of a task in the task tree from within the callbacks. Attributes ---------- task_name : str The name of the task this context is responsible for. task_id : int The identifier of the task this context is responsible for. It uniquely identifies the task among its siblings. max_subtasks : int or None The maximum number of children tasks for this task. 0 means it's a leaf. None means the maximum number of subtasks is not known in advance. sequential_subtasks : bool Whether this context's subtasks are sequential. When True, children contexts' have consecutive integer task_ids starting from 0. estimator_name : str The name of the estimator that holds this context. parent : CallbackContext or None The parent context of this context. None if this context is the root. root_uuid : uuid.UUID instance The UUID of the root context. All contexts in the same task tree have the same root UUID that is used to identify the task tree itself. init_time : datetime.datetime The time when the context was initialised, in the UTC timezone. source_estimator_name : str or None The name of the estimator that holds the parent task this task was merged with. None if it was not merged with another context. source_task_name : str or None The task name of the parent task this task was merged with. None if it was not merged with another context. c|j|}t|dg|_|jj|_||_||_||_||_ d|_ tj|_ tjt j"|_i|_d|_d|_t-|dr3|j.}|j1||j2dz|_|Sd|_|S)a#Private constructor to create a root context.

This method is called on a sub-estimator's root task to merge it with a meta-estimator's leaf task. The sub-estimator's task tree is therefore attached to the meta-estimator's task tree. The root node of the sub-estimator's task tree and the leaf node of the meta-estimator's task tree are both represented by a single node in this combined task tree. rz$Cannot merge callback context (task r<z) with callback context (task z#) because the latter is not a leaf.N) rr>rrrrrr"r$r#)r5 other_contexts r,r&zCallbackContext._merge_withs  % % *6t~~6H&&'(&003> //00SU $** $,, &00;? **4<<8!. 7 7%2%A%A"r.Nc @|jr+|)td|jd|d|jd|js+|)td|jd|d|jd|t |j }t j|||||S)aCreate a context for a subtask of the current task.
