FBB::X2a - Objects performing x-to-Ascii conversions
#include <bobcat/x2a> Linking option: -lbobcat
FBB:X2a objects convert values of any (insertable) type to text. The returned text is automatically made available as a standard C++ string.
FBB All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
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 and the copy assignment operator are available.
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.
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.
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.
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.
bobcat/x2a - defines the class interface
The functionality of this class is to a large extent also offered by the C++ function std::to_string.
