# Google Tasks API . tasks

## Instance Methods

Clears all completed tasks from the specified task list. The affected tasks will be marked as 'hidden' and no longer be returned by default when retrieving all tasks for a task list.

Close httplib2 connections.

Deletes the specified task from the task list. If the task is assigned, both the assigned task and the original task (in Docs, Chat Spaces) are deleted. To delete the assigned task only, navigate to the assignment surface and unassign the task from there.

Returns the specified task.

Creates a new task on the specified task list. Tasks assigned from Docs or Chat Spaces cannot be inserted from Tasks Public API; they can only be created by assigning them from Docs or Chat Spaces. A user can have up to 20,000 non-hidden tasks per list and up to 100,000 tasks in total at a time.

Returns all tasks in the specified task list. Doesn't return assigned tasks by default (from Docs, Chat Spaces). A user can have up to 20,000 non-hidden tasks per list and up to 100,000 tasks in total at a time.

Retrieves the next page of results.

Moves the specified task to another position in the destination task list. If the destination list is not specified, the task is moved within its current list. This can include putting it as a child task under a new parent and/or move it to a different position among its sibling tasks. A user can have up to 2,000 subtasks per task.

Updates the specified task. This method supports patch semantics.

Updates the specified task.

`list_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

            Returns:
              A request object that you can call 'execute()' on to request the next
              page. Returns None if there are no more items in the collection.

`move(tasklist, task, destinationTasklist=None, parent=None, previous=None, x__xgafv=None)`

    Moves the specified task to another position in the destination task list. If the destination list is not specified, the task is moved within its current list. This can include putting it as a child task under a new parent and/or move it to a different position among its sibling tasks. A user can have up to 2,000 subtasks per task.

    Args:
      tasklist: string, Task list identifier. (required)
      task: string, Task identifier. (required)
      destinationTasklist: string, Optional. Destination task list identifier. If set, the task is moved from tasklist to the destinationTasklist list. Otherwise the task is moved within its current list. Recurrent tasks cannot currently be moved between lists.
      parent: string, Optional. New parent task identifier. If the task is moved to the top level, this parameter is omitted. The task set as parent must exist in the task list and can not be hidden. Exceptions: 1. Assigned and repeating tasks cannot be set as parent tasks (have subtasks), or be moved under a parent task (become subtasks). 2. Tasks that are both completed and hidden cannot be nested, so the parent field must be empty.
      previous: string, Optional. New previous sibling task identifier. If the task is moved to the first position among its siblings, this parameter is omitted. The task set as previous must exist in the task list and can not be hidden. Exceptions: 1. Tasks that are both completed and hidden can only be moved to position 0, so the previous field must be empty.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
