bsl::ostream & | print (bsl::ostream &stream, int level=0, int spacesPerLevel=4) const |
Utility for printing bsl::optional
to standard output streams. This class has operator<<
defined for it, so it can be used, for example, in ball
logs.

Format this object to the specified output stream
at the (absolute value of) the optionally specified indentation level
and return a reference to stream
. If level
is specified, optionally specify spacesPerLevel
, the number of spaces per indentation level for this and all of its nested objects. If level
is negative, suppress indentation of the first line. If spacesPerLevel
is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level
). If stream
is not valid on entry, this operation has no effect.
