Expand description

Create expression that selects map items nearest to key and greater by index. Expression returns selected data specified by returnType.

Examples for ordered map [{0=17},{4=2},{5=15},{9=10}]:

  • (value,index) = [selected items]
  • (5,0) = [{5=15},{9=10}]
  • (5,1) = [{9=10}]
  • (5,-1) = [{4=2},{5=15},{9=10}]
  • (3,2) = [{9=10}]
  • (3,-2) = [{0=17},{4=2},{5=15},{9=10}]
