Class UnflatTupleOperator

java.lang.Object

org.thales.punch.libraries.punchlang.operator.UnflatTupleOperator

public class UnflatTupleOperator
extends Object

The ToTuple operator performs the opposite action than the ToFlatTuple operator.

Say you have an input tuple containing

 
    { "top.a"="1" "top.b"="hello world" "c"="[1,2,3]" }
 

If you run :

 
        Tuple nested  = unflatTuple().on(input);
 
 

it produces a tuple 'nested' containing:

 
        * { "top" : { "a"=1, "b"="hello world"}, "c"=[1,2,3] }
