Snapshot Preview
Using the preview changes button on the snapshots page of the ModelBuilder wizard (see Step 6 - Specify Snapshot Settings), you can preview the differences before performing the synchronization into the model.
The snapshot preview presents the differences between the selected snapshot and the current state of the GIS in a tabular view.
The Tables
On the left is a list of the tables that are part of the ModelBuilder configuration.
The icon indicates the state of the table as follows:
The Differences Table
In the table on the right shows the differences for the selected table.
The first column is always the "Accept?" column. For an element with a modified state of ADDED, DELETED OR MODIFIED, this will be editable. For those elements with an UNMODIFIED state, this cell will be read-only.
Icons in the second column is a visual indicator of the state of that row as follows:
The third column is the key field of the table. The label can vary depending on the settings.
The columns following the key field are the mapped fields for the table. Differences are highlighted. A difference is considered a change between the selected snapshot and the current GIS state. The default highlight color is light pink. You can change the highlight color by opening the options dialog. See for additional details.
If an element has a difference in its geometry, it will show the appropriate icon in the second column. Any differences in the mapped fields will highlight as well. The geometry change icon supersedes the value change icon.
Global Edit
Above the differences table is the global edit button. You can also access global edit by right-clicking the "Accept?" column and clicking Global Edit. You can also select in the table and right-click and click Global Edit.
If you select in the table, the global edit operation will apply to the selection but only for rows with a state of ADDED, DELETED or MODIFIED. If only a single cell is selected the global edit operation applies to all rows in the current view with a state of ADDED, DELETED or MODIFIED.
When global editing, it only applies to rows currently in view.
Toolbar
- Save: The save button will write to the snapshot files the "Accept?" state for each row with a state of ADDED, DELETED or MODIFIED.
- Toggle Filter: This button
has a drop-down menu with five options. Checking one or more options will
include those changes in the table. Unchecking an option has the opposite
effect: Unchecking "Show Value Changes" will exclude rows where at least one
mapped field has changed. Note that if you check "Show Geometry Changes" but
exclude "Show Value Changes" you may see rows where mapped fields have changed
but the geometry has also changed. The options are as follows:
- Apply Filter: Toggles the currently defined filter on/off.
- Show Value Changes: Include rows where at least one mapped field has changed.
- Show Geometry Changes: Include rows where geometry has changed.
- Show Adds: Include those elements added to the model.
- Show Deletes: Include those elements removed from the model.
- Options: The options button opens the options dialog (see Snapshot Preview Options).
