ChangeContext (Gerrit Review Plugin API Documentation)

All Superinterfaces:

Context
```
public interface ChangeContext
extends Context
```
Context for performing the BatchUpdateOp.updateChange(com.google.gerrit.server.update.ChangeContext) phase.
A single ChangeContext corresponds to updating a single change; if a BatchUpdate spans multiple changes, then multiple ChangeContext instances will be created.

- Method Detail
  - getUpdate
```
ChangeUpdate getUpdate(PatchSet.Id psId)
```
    Get an update for this change at a given patch set.
    A single operation can modify changes at different patch sets. Commits in the NoteDb graph within this update are created in patch set order.
    To get the current patch set ID, use PatchSetUtil.current(com.google.gerrit.reviewdb.server.ReviewDb, com.google.gerrit.server.notedb.ChangeNotes).
    
    Parameters:
    
    psId - patch set ID.
    
    Returns:
    
    handle for change updates.
  - getNotes
```
ChangeNotes getNotes()
```
    Get the up-to-date notes for this change.
    The change data is read within the same transaction that BatchUpdateOp.updateChange(ChangeContext) is executing.
    
    Returns:
    
    notes for this change.
  - dontBumpLastUpdatedOn
```
void dontBumpLastUpdatedOn()
```
    Don't bump the value of Change.getLastUpdatedOn().
    If called, don't bump the timestamp before storing to ReviewDb. Only has an effect in ReviewDb, and the only usage should be to match the behavior of NoteDb. Specifically, in NoteDb the timestamp is updated if and only if the change meta graph is updated, and is not updated when only drafts are modified.
  - deleteChange
```
void deleteChange()
```
    Instruct BatchUpdate to delete this change.
    If called, all other updates are ignored.
  - getChange
```
default Change getChange()
```
    Returns:
    
    change corresponding to getNotes().
