      • getTargetCharLiteralFromANTLRCharLiteral

        public String getTargetCharLiteralFromANTLRCharLiteral​(CodeGenerator generator,
                                                               String literal)
        Description copied from class: Target
        Convert from an ANTLR char literal found in a grammar file to an equivalent char literal in the target language. For most languages, this means leaving 'x' as 'x'. Actually, we need to escape ' ' so that it doesn't get converted to \n by the compiler. Convert the literal to the char value and then to an appropriate target char literal. Expect single quotes around the incoming literal.

      • getMaxCharValue

        public int getMaxCharValue​(CodeGenerator generator)
        Description copied from class: Target
        Some targets only support ASCII or 8-bit chars/strings. For example, C++ will probably want to return 0xFF here.

      • isValidActionScope

        public boolean isValidActionScope​(int grammarType,
                                          String scope)
        Description copied from class: Target
        Is scope in @scope::name {action} valid for this kind of grammar? Targets like C++ may want to allow new scopes like headerfile or some such. The action names themselves are not policed at the moment so targets can add template actions w/o having to recompile ANTLR.
        Overrides:
        isValidActionScope in class Target
