All exceptions thrown by Xapian are subclasses of Xapian::Error.
This class can not be instantiated directly - instead a subclass should be used.
|
default |
Default copy constructor.
We explicitly specify this to avoid warnings from GCC 9 (from -Wdeprecated-copy which is enabled by -Wextra).
|
inlinenoexcept |
Optional context information.
This context is intended for machine use (for example to know which remote server an error came from), but it is typically a plain-text string, and so also fit for human consumption.
const char* Xapian::Error::get_error_string | ( | ) | const |
Returns any system error string associated with this exception.
The system error string may come from errno, h_errno (on UNIX), or GetLastError() (on MS Windows). If there is no associated system error string, NULL is returned.
