NAME

       FBB::X2a - Objects performing x-to-Ascii conversions

SYNOPSIS

       #include <bobcat/x2a>
       Linking option: -lbobcat

DESCRIPTION

       FBB:X2a  objects convert values of any (insertable) type to text. The returned text is automatically made
       available as a standard C++ string.

NAMESPACE

       FBB
       All constructors, members, operators and manipulators, mentioned in this man-page,  are  defined  in  the
       namespace FBB.

INHERITS FROM

       std::ostringstream

CONSTRUCTORS

       o      X2a(T const &value):
              In this constructor T may be any type that can be inserted into an o[string]stream.

       o      X2a(double value, size_t behind):
              Double  value  is  truncated  to  behind digits behind the decimal dot.  If a value doesn’t occupy
              behind digits behind the decimal point, then missing digits are added as 0. For example,  a  value
              of 7.1, will be displayed as 7.10 if two digits behind the decimal dot are requested. A value of 7
              will be displayed as 7.00.

       o      X2a(double value, size_t width, size_t behind, std::ios::fmtflags flags = std::ios::right):
              The  value  is  displayed  over  width  character  positions, extending the amount if the value so
              requires. The converted value is placed right-aligned into the field  of  width  characters.   The
              copy constructor is available as well.

STATIC MEMBER FUNCTION

       o      bool lastFail():
              This  member returns true if the last conversion failed (i.e., the object’s fail() member returned
              true  and  returns  false  otherwise).   This  member  allows  checks  on  the  success   of   the
              extraction/conversion  using  anonymous  A2x  objects.  The  member  also  returns  true  when  no
              conversions have as yet been performed.
              Note that this member is a thread-unsafe static member: in a multithreaded program  locks  may  be
              required to ensure that the proper conversion result is inspected.

MEMBER FUNCTIONS

       All  members  of  std::ostringstream  are  available, as FBB::X2a inherits from this class. In particular
       ostringstream::str() can be used to obtain the contents of an X2a object’s text buffer.

OVERLOADED OPERATORS

       o      operator std::ostream &operator<<(std::ostream &ostr, X2a const &x2a):
              This conversion operator inserts the textual representation of the x2a parameter  value  into  the
              provided ostream.

       o      operator std::string const() const:
              this  conversion operator returns the information stored inside the FBB::X2a object.  The standard
              overloaded assignment operator is available as well.

EXAMPLE

           string is(X2a(5));      // initializes `is’ with "5"
           string ds(X2a(5.25));   // initializes `ds’ with "5.25"

           cout << X2a(7.0 / 3, 4) << endl;
                                   // display a value using 4 digits behind the
                                   // decimal dot.
           cout << X2a(7.0 / 3, 8, 4) << endl;
                                   // display a value over 8 positions, right
                                   // adjusted, 4 digits behind the decimal dot.
           cout << X2a(7.0 / 3, 8, 4, std::ios::left) << endl;
                                   // display a value over 8 positions, left
                                   // adjusted, 4 digits behind the decimal dot.
