                      throws CompileError
        Inserts a cast operator to the return type. If the return type is void, this does nothing.
        Throws:
        CompileError

      • isParamListName

        public boolean isParamListName​(ASTList args)

      • recordReturnType

        public int recordReturnType​(CtClass type,
                            java.lang.String castName,
                            java.lang.String resultName,
                            SymbolTable tbl)
                     throws CompileError
        Makes a cast to the return type ($r) available. It also enables $_.

        If the return type is void, ($r) does nothing. The type of $_ is java.lang.Object.

        Parameters:
        resultName - null if $_ is not used.
        Returns:
        -1 or the variable index assigned to $_.
        Throws:
        CompileError

      • recordType

        public void recordType​(CtClass t)
        Makes $type available.

      • recordParams

        public int recordParams​(CtClass[] params,
                        boolean isStatic,
                        java.lang.String prefix,
                        java.lang.String paramVarName,

                        SymbolTable tbl)
                 throws CompileError
        Makes method parameters $0, $1, ..., $args, $$, and $class available. $0 is equivalent to THIS if the method is not static. Otherwise, if the method is static, then $0 is not available.
        Throws:
        CompileError

      • recordParams

        public int recordParams​(CtClass[] params,
                        boolean isStatic,
                        java.lang.String prefix,
                        java.lang.String paramVarName,

                        java.lang.String target,
                        SymbolTable tbl)
                 throws CompileError
        Makes method parameters $0, $1, ..., $args, $$, and $class available. $0 is available only if use0 is true. It might not be equivalent to THIS.
        Parameters:
        params - the parameter types (the types of $1, $2, ..)
        prefix - it must be "$" (the first letter of $0, $1, ...)
        paramVarName - it must be "$args"
        paramsName - it must be "$$"
        use0 - true if $0 is used.
        paramBase - the register number of $0 (use0 is true) or $1 (otherwise).
        target - the class of $0. If use0 is false, target can be null. The value of "target" is also used as the name of the type represented by $class.
        isStatic - true if the method in which the compiled bytecode is embedded is static.
        Throws:
        CompileError

      • recordVariable

                           int varNo,
                           SymbolTable tbl)
                    throws CompileError
        Makes the given variable name available.
        Parameters:
