A sequence of dot-separated identifiers, followed by any number of array square brackets. Represents a fully-qualified name as defined in the Java Language Specification, section 6.7.

Examples:

int
MyClass
java.lang.Integer
int[][]
MyClass[]
java.lang.Integer[][][]

in

 package org.checkerframework.checker.signature;
 public class SignatureChecker {
   private class Inner {}
 }

the fully-qualified names for the two types are org.checkerframework.checker.signature.SignatureChecker and org.checkerframework.checker.signature.SignatureChecker.Inner.

Fully-qualified names and binary names are the same for top-level classes and only differ by a '.' vs. '$' for inner classes.
