Examples

Get all elements in the range from entity 1 to entity 4

final GetElementsInRanges operation = new GetElementsInRanges.Builder()
        .input(new Pair<>(new EntitySeed(1), new EntitySeed(4)))
        .build();

{
  "class" : "GetElementsInRanges",
  "input" : [ {
    "class" : "Pair",
    "first" : {
      "EntitySeed" : {
        "class" : "EntitySeed",
        "vertex" : 1
      }
    },
    "second" : {
      "EntitySeed" : {
        "class" : "EntitySeed",
        "vertex" : 4
      }
    }
  } ]
}

g.GetElementsInRanges( 
  input=[

The results are:
