All Known Implementing Classes:

ProcessInstanceHistoryLogQueryImpl
```
@Internal
public interface ProcessInstanceHistoryLogQuery
```
Allows to fetch the ProcessInstanceHistoryLog for a process instance. Note that every includeXXX() method below will lead to an additional query. This class is actually a convenience on top of the other specific queries such as HistoricTaskInstanceQuery, HistoricActivityInstanceQuery, ... It will execute separate queries for each included type, order the data according to the date (ascending) and wrap the results in the ProcessInstanceHistoryLog.
