Retrieve all of the child events for a given parent event.
|
|
|
|
|
|
|
|
|
|
Note that when paginating the `from` token should be "after" the `to` token in
|
|
|
|
|
terms of topological ordering, because it is only possible to paginate "backwards"
|
|
|
|
|
through events, starting at `from`.
|
|
|
|
|
|
|
|
|
|
For example, passing a `from` token from page 2 of the results, and a `to` token
|
|
|
|
|
from page 1, would return the empty set. The caller can use a `from` token from
|
|
|
|
|
page 1 and a `to` token from page 2 to paginate over the same range, however.
