Exception to be thrown when a measurement algorithm experiences a known failure mode.
In addition to the usual message, MeasurementError must be constructed with the bit of the algorithm-specific flag that indicates the known failure mode. This allows the measurement framework to set that flag upon failure. Typically, this flag bit is also used to look up the message from the algorithm classes FlagDefinition list; the common pattern is:

Return a copy of the exception as an Exception pointer.
Can be overridden by derived classes that add data or methods.
Reimplemented from lsst.pex::exceptions::Exception.

Return the flag bit associated with the error.

Retrieve the list of tracepoints associated with an exception.

inlinevirtual |
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 from lsst.pex::exceptions::Exception.

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.
