--
-- This Java grammar is almost identical to the grammar defined in
-- chapter 19 of the Java Language Specification manual together with
-- the additional rules found in the 1.1 document. It is written here
-- in JIKES PG format with semantic actions following each rule. In
-- specifying the rules we enclosed all terminal symbols in single
-- quotes so that they can be quickly distinguished from
-- non-terminals. Optional symbols are suffixed with a question mark (?)
-- and the rules expanding such definitions can be found at the end.
--
-- This grammar is totally faithful to the original rules except that
-- some syntactic markers: PackageHeaderMarker, MethodHeaderMarker and
-- BodyMarker, were added to allow the parser to skip certain irrelevant
-- syntactic components when they are not needed.
--
-- The file javaact.h produced by JIKESPG from this file (java.g) contains a
-- very readable definition of the grammar rules together with their
-- associated semantic actions. That file is marked with appropriate
-- location directives (automatically generated) which instructs the C++
-- compiler to issue error messages in terms of this file (java.g).
-- Therefore, though the user is encouraged to read javaact.h, no
-- change should ever be made to that file. Instead, changes should
-- always be made in this file and javaact.h should be regenerated
-- using JIKESPG.
