FBB::X2a(3bobcat)					      X-to-ASCII conversions						 FBB::X2a(3bobcat)

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.
