Class ShortLiteralNode

java.lang.Object

org.checkerframework.dataflow.cfg.node.Node

org.checkerframework.dataflow.cfg.node.ValueLiteralNode

org.checkerframework.dataflow.cfg.node.ShortLiteralNode

public class ShortLiteralNode
extends ValueLiteralNode

A node for a short literal. For example:

   5
   0x8fff
 

Java source and the AST representation do not have "short" literals. They have integer literals that may be narrowed to shorts depending on context. If we use explicit NarrowingConversionNodes, do we need ShortLiteralNodes too? TODO: Decide this question.
