HistoryService (camunda BPM Javadocs 7.3.7-ee)

All Known Implementing Classes:

HistoryServiceImpl
```
public interface HistoryService
```
Service exposing information about ongoing and past process instances. This is different from the runtime information in the sense that this runtime information only contains the actual runtime state at any given moment and it is optimized for runtime process execution performance. The history information is optimized for easy querying and remains permanent in the persistent storage.

    Throws:
    
    AuthorizationException - If the user has no Permissions.DELETE_HISTORY permission on Resources.PROCESS_DEFINITION.
  - deleteHistoricProcessInstance
```
void deleteHistoricProcessInstance(String processInstanceId)
```
    Deletes historic process instance. All historic activities, historic task and historic details (variable updates, form properties) are deleted as well.
    
    Throws:
    
    AuthorizationException - If the user has no Permissions.DELETE_HISTORY permission on Resources.PROCESS_DEFINITION.
  - deleteUserOperationLogEntry
```
void deleteUserOperationLogEntry(String entryId)
```
    Deletes a user operation log entry. Does not cascade to any related entities.
    
    Throws:
    
    AuthorizationException - If the user has no Permissions.DELETE_HISTORY permission on Resources.PROCESS_DEFINITION.
  - deleteHistoricCaseInstance
```
void deleteHistoricCaseInstance(String caseInstanceId)
```
    Deletes historic case instance. All historic case activities, historic task and historic details are deleted as well.
  - createNativeHistoricProcessInstanceQuery
```

```
String getHistoricJobLogExceptionStacktrace(String historicJobLogId)
```
    Returns the full stacktrace of the exception that occurs when the historic job log with the given id was last executed. Returns null when the historic job log has no exception stacktrace.
