public class WideningConversionNode extends Node
A node for the widening primitive conversion operation. See JLS 5.1.2 for the definition of widening primitive conversion.

A WideningConversionNode does not correspond to any tree node in the parsed AST. It is introduced when a value of some primitive type appears in a context that requires a different primitive with more bits of precision.

      Type Parameters:
      R - result type of the operation
      P - parameter type
      Parameters:
