protected Option

The protected method option indicates that the method can be referenced only by methods in the same class or its subclasses.

Alternatively, you can specify this method option by using the Protected check box in the Jade Method Definition or External Method Definition dialog.

As the protected option is unset by default, you can use the methods access option on the Schema sheet of the Preferences dialog to change the default options for your schemas. (For details, see "Maintaining Schema Options", in Chapter 2 of the Development Environment User's Guide.)

The following examples show methods with the protected option specified in the signature.

backupException(ex: Exception): Integer updating, protected;
begin
    if ex.errorCode = JErr_DbFileNotFound or
             ex.errorCode = JErr_DbUserAbort then
        return Ex_Resume_Next;
    endif;
    // pass all other exceptions to the next handler in the chain
    return Ex_Pass_Back;
end;

addressLine(line: Integer): String protected;
// returns a specific line of an address
vars
    addr1, addr2 : Integer;
    addressOut   : String;
    char         : Character;
begin
    addr1 := 0;
    addr2 := 1;
    while addr1 < address.length do
        addr1 := addr1 + 1;
        char  := address[addr1:1].Character;
        if char <> Cr and char <> Lf  and char <> ',' then
            addressOut := addressOut & char;
        else
            if addr2 = line then
                break;
            else
                addressOut := "";
                addr2 := addr2 + 1;
            endif;
        endif;
    endwhile;
    if addr2 = line then
        return addressOut.trimLeft;
    endif;
end;
