This class represents context variable and register value of a functional type A => B. When variable or register is accessed using
getVar[A => B](id).get
orbox.getReg[A => B].get an instance of this class is returned.
It internally transforms a given
tree
into executable function. This it similar to what happens during validation of propositions in the input boxes: - size check of underlying ErgoTree against limits - construction ofcalcF
andcostF
graphs, both are stored together with resulting function. - check the types ofcalcF
graph to be compatible with expected types A and B If anything goes wrong, this operation fails and if it is used in the script, the script also fails.When f is obtained as
val f = getVar[Int => Int](id).get
then any applicationf(x)
involves size estimation using underlyingcostF(x)
.
