Examples of com.sun.tools.javac.parser.Parser

com.sun.tools.javac.parser.Parser
The parser maps a token sequence into an abstract syntax tree. It operates by recursive descent, with code derived systematically from an LL(1) grammar. For efficiency reasons, an operator precedence scheme is used for parsing binary operation expressions.
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.
