annotate libinterp/corefcn/symrec.h @ 31855:1daf8bfceac3

default or disable more ctors, dtors, and assignment ops In most classes in liboctave and libinterp (except for the files in octave-value subdirectory) that had at least one of the following functions defined default constructor copy constructor copy assignment operator destructor declare all of them. In most cases, this means declaring default or deleted functions. In some cases, explicit definitions have been replaced by equivalent default functions. In some cases, default or deleted move constructors and move assignment operators have also been declared.
