Checkpoints Tab
The Checkpoints tab displays a list of saved checkpoints that preserve a snapshot of the state of objects in memory at the time the checkpoint was reached.
Checkpoints
This list displays the checkpoints currently available for review. Select to only display checkpoints you’ve created since opening the Developer Console. Deselect this option to display all checkpoints currently saved for your organization, including newly-generated ones created by other users.
Each checkpoint in the list displays this information:
| Column | Description |
|---|---|
| Namespace | The namespace of the package containing the checkpoint. |
| Class | The Apex class containing the checkpoint. |
| Line | The line number marked with the checkpoint. |
| Time | The time the checkpoint was reached. |
Right click any column header to sort the information in the column. You can also select which columns you want displayed in the Checkpoints list.
To open a checkpoint, double-click it. The checkpoint opens in the Checkpoint Inspector.
Checkpoint Locations
This list provides the location of each checkpoint in the source code. Each item in the list displays this information:
| Column | Description |
|---|---|
| File | The name of the Apex class that contains the checkpoint. |
| Line | The line number marked with the checkpoint. |
| Iteration | If the checkpoint is in a loop, this value indicates the iteration at which the checkpoint is captured. |
By default, the iteration is 1, which means that the checkpoint is saved the first time the line of source code executes. You can use a different iteration, for example, to investigate why a loop does not terminate when expected. To change the iteration, click the cell you want to change and enter a new number. Only one checkpoint will be captured for a specific line of code, no matter how many times it’s executed during a request.
Set checkpoints locations from the Source Code Editor. Checkpoint locations persist until you click Clear or until you close the Developer Console.
