Inherited by IWvStream, WvBdbHashBase, WvMagicCircle, WvRSAKey, and WvShmZone.
Collaboration diagram for WvError:
It can have either a system error value, like those defined in errno.h, or an arbitrary error string. In either case, it can return a string representation of the error message.

Public Member Functions | |
WvError () | |
virtual | ~WvError () |
virtual bool | isok () const |
By default, returns true if geterr() == 0. | |
virtual int | geterr () const |
If isok() is false, return the system error number corresponding to the error, -1 for a special error string (which you can obtain with errstr()) or 0 on end of file. | |
virtual WvString | errstr () const |
virtual void | seterr (int _errnum) |
Set the errnum variable -- we have an error. | |
void | seterr (WvStringParm specialerr) |
void | seterr (WVSTRING_FORMAT_DECL) |
void | seterr (const WvError &err) |
void | noerr () |
Reset our error state - there's no error condition anymore. | |

If isok() is false, return the system error number corresponding to the error, -1 for a special error string (which you can obtain with errstr()) or 0 on end of file.

By default, returns true if geterr() == 0. Might be overridden so that isok() == false even though no error code has been specified.

Set the errnum variable -- we have an error. If called more than once, seterr() doesn't change the error code away from the previous one. That way, we remember the _original_ cause of our problems. Subclasses may want to override seterr(int) to shut themselves down (eg. WvStream::close()) when an error condition is set. Note that seterr(WvString) will call seterr(-1). Reimplemented in WvStream.
