getEditFeature

Feature getEditFeature()

Returns:

the layer that is "currently" selected

isEditing

boolean isEditing()

Returns true if there is a currently active transaction (editing has occured and not been committed). false is returned if there is no current transaction. If false is returned it is understood that no editing is occurring.
