The get() method reads the contents of a region object and converts it into an array of strings (because any region may contain several lines). How the region is defined, depends on the type of source data; see region and createRegion().
get(in_Region)
in_Region
A region object. What type of object this is depends on the type of source data, however in any case the region object can be created with a call to region.createRegion(); see createRegion().
