Resumen

Refreshes the map views containing the specified layers.

Debate

Use the RefreshLayer function to refresh the map view after edits have taken place. This can be useful to run when updates to a table, such as with a cursor, do not trigger a refresh of the map view. This will refresh all visible layers in the map view containing the specified layer.
