Examples of com.sun.tools.javac.code.Symbol

com.sun.tools.javac.code.Symbol
Root class for Java symbols. It contains subclasses for specific sorts of symbols, such as variables, methods and operators, types, packages. Each subclass is represented as a static inner class inside Symbol.
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.
