00004  *
00005  * We reserve no LEGAL rights to the Purdue Compiler Construction Tool
00006  * Set (PCCTS) -- PCCTS is in the public domain.  An individual or
00007  * company may do whatever they wish with source code distributed with
00008  * PCCTS or the code generated by PCCTS, including the incorporation of
00009  * PCCTS, or its output, into commerical software.
00010  *
00011  * We encourage users to develop software with PCCTS.  However, we do ask
00012  * that credit is given to us for developing PCCTS.  By "credit",
00013  * we mean that if you incorporate our source code into one of your
00014  * programs (commercial product, research project, or otherwise) that you
00015  * acknowledge this fact somewhere in the documentation, research report,
00016  * etc...  If you like PCCTS and have developed a nice tool with the
00017  * output, please mention that you developed it using PCCTS.  In
00018  * addition, we ask that this header remain intact in our source code.
00019  * As long as these guidelines are kept, we expect to continue enhancing
00020  * this system and expect to make other tools available as they are
00021  * completed.

00033 /* This is really a behavior or protocol; it merely indicates the behavior
00034  * required of the input and output of an ANTLRTokenBuffer.  You could
00035  * subclass it, but you can also just pass any old pointer to ANTLRTokenBuffer
00036  * with a type cast (in which case, your getANTLRToken() would have to
00037  * explicitly cast the input pointer to your REAL type (typically your lexer)).
