From 70299a3eb281d3083829a0f97c809e2f4af59fe2 Mon Sep 17 00:00:00 2001 From: bjculkin Date: Mon, 20 Mar 2017 19:18:27 -0400 Subject: Work more on parser This does more work on the parser, including moving from the old LineReader/Scanner combo to BlockReader. It includes more syntax checking, but still doesn't actually do anything. With some dummy methods in RGrammarBuilder, should be able to see if the basic file parser is working correctly. Where blocks and their syntax still need to implemented, and actual pragma implementations need to be provided. --- .../java/bjc/rgens/newparser/GrammarException.java | 39 ++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 RGens/src/main/java/bjc/rgens/newparser/GrammarException.java (limited to 'RGens/src/main/java/bjc/rgens/newparser/GrammarException.java') diff --git a/RGens/src/main/java/bjc/rgens/newparser/GrammarException.java b/RGens/src/main/java/bjc/rgens/newparser/GrammarException.java new file mode 100644 index 0000000..c9f2723 --- /dev/null +++ b/RGens/src/main/java/bjc/rgens/newparser/GrammarException.java @@ -0,0 +1,39 @@ +package bjc.rgens.newparser; + +/** + * The exception thrown when something goes wrong while parsing a + * grammar. + * + * @author student + * + */ +public class GrammarException extends RuntimeException { + /* + * Serialization ID. + */ + private static final long serialVersionUID = -7287427479316953668L; + + /** + * Create a new grammar exception with the specified message. + * + * @param msg + * The message for this exception. + */ + public GrammarException(String msg) { + super(msg); + } + + /** + * Create a new grammar exception with the specified message and + * cause. + * + * @param msg + * The message for this exception. + * + * @param cause + * The cause of this exception. + */ + public GrammarException(String msg, Exception cause) { + super(msg, cause); + } +} \ No newline at end of file -- cgit v1.2.3
