public class Program
extends Node

A program is the first-class citizen in JSONiq scripting syntax. A program corresponds to the body of a block expression. The final expression may be omitted. In this case, the final expression is considered the empty expression. The result of a program is the result of executing, if present, an expression. A program forms a tree of statements and possibly an expression.
