java.lang.Object

org.antlr.v4.parse.ScopeParser

public class ScopeParser
extends Object

Parse args, return values, locals rule[arg1, arg2, ..., argN] returns [ret1, ..., retN] text is target language dependent. Java/C#/C/C++ would use "int i" but ruby/python would use "i".

Method Detail

parseTypedArgList

public static AttributeDict parseTypedArgList(String s,
                              ErrorManager errMgr)

Given an arg or retval scope definition list like Map, int[] j3, char *foo32[3] or int i=3, j=a[34]+20 convert to an attribute scope.

parse

public static AttributeDict parse(String s,
                  char separator,
                  ErrorManager errMgr)

parseAttributeDef

public static Attribute parseAttributeDef(String decl,
                          ErrorManager errMgr)

For decls like "String foo" or "char *foo32[]" compute the ID and type declarations. Also handle "int x=3" and 'T t = new T("foo")' but if the separator is ',' you cannot use ',' in the initvalue unless you escape use "\," escape.

splitDecls

public static List<String> splitDecls(String s,
                      int separatorChar)

Given an argument list like x, (*a).foo(21,33), 3.2+1, '\n', "a,oo\nick", {bl, "fdkj"eck}, ["cat\n,", x, 43] convert to a list of attributes. Allow nested square brackets etc... Set separatorChar to ';' or ',' or whatever you want.

_splitArgumentList

public static int _splitArgumentList(String actionText,
                     int start,
                     int targetChar,
                     int separatorChar,
                     List<String> args)
