Class NarrowingConversionNode

java.lang.Object

org.checkerframework.dataflow.cfg.node.Node

org.checkerframework.dataflow.cfg.node.NarrowingConversionNode

public class NarrowingConversionNode
extends Node

A node for the narrowing primitive conversion operation. See JLS 5.1.3 for the definition of narrowing primitive conversion.

A NarrowingConversionNode 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.
