Class DeferredAttr

java.lang.Object

com.sun.tools.javac.tree.JCTree.Visitor

com.sun.tools.javac.comp.DeferredAttr

public class DeferredAttr
extends JCTree.Visitor

This is an helper class that is used to perform deferred type-analysis. Each time a poly expression occurs in argument position, javac attributes it with a temporary 'deferred type' that is checked (possibly multiple times) against an expected formal type.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
