Public Member Functions | |
void | addMessage (char const *file, int line, char const *func, std::string const &message) |
Add a tracepoint and a message to an exception before rethrowing it (access via LSST_EXCEPT_ADD). | |
Traceback const & | getTraceback (void) const noexcept |
Retrieve the list of tracepoints associated with an exception. | |
virtual std::ostream & | addToStream (std::ostream &stream) const |
Add a text representation of this exception, including its traceback with messages, to a stream. | |
virtual char const * | what (void) const noexcept |
Return a character string summarizing this exception. | |
T | what (T... args) |
virtual char const * | getType (void) const noexcept |
Return the fully-specified C++ type of a pointer to the exception. | |
virtual Exception * | clone (void) const |
Return a copy of the exception as an Exception pointer. | |
Reports attempts to access elements using an invalid key.
This exception may represent lookup failures in classes that resemble C++ maps or Python dictionaries, but it may also be used when the relationship between an identifier and a resource is more abstract.
In Python, this exception inherits from builtins.LookupError
.
py::key_error
when appropriate. Some Python language constructs check for exceptions that are exactly KeyError
rather than a sub- or superclass.

Add a tracepoint and a message to an exception before rethrowing it (access via LSST_EXCEPT_ADD).
[in] | file | Filename (automatically passed in by macro). |
[in] | line | Line number (automatically passed in by macro). |
[in] | func | Function name (automatically passed in by macro). |
[in] | message | Additional message to associate with this rethrow. |

virtualinherited |
Add a text representation of this exception, including its traceback with messages, to a stream.
[in] | stream | Reference to an output stream. |
Definition at line 81 of file Exception.cc.
|
virtualinherited |
Return a copy of the exception as an Exception pointer.
Can be overridden by derived classes that add data or methods.
Reimplemented in lsst::meas::base::MeasurementError.
Definition at line 103 of file Exception.cc.
|
noexceptinherited |
Retrieve the list of tracepoints associated with an exception.
Definition at line 79 of file Exception.cc.
|
virtualnoexceptinherited |
Return the fully-specified C++ type of a pointer to the exception.
This is overridden by derived classes (automatically if the LSST_EXCEPTION_TYPE macro is used). It is used by the Python interface.
Reimplemented in lsst::meas::base::MeasurementError.
Definition at line 101 of file Exception.cc.
|
virtualnoexceptinherited |
Return a character string summarizing this exception.
This combines all the messages added to the exception, but not the type or traceback (use the stream operator to get this more detailed information).
Not allowed to throw any exceptions.
Definition at line 99 of file Exception.cc.
