COMMENT(manpage, section, releasedate, archive, short name)
manpage(FBB::X2a)(3bobcat)(_CurYrs_)(libbobcat1-dev__CurVers_-x.tar.gz)
(X-to-ASCII conversions)
manpagename(FBB::X2a)(Objects performing x-to-Ascii conversions)
manpagesynopsis()
bf(#include <bobcat/x2a>)nl()
Linking option: tt(-lbobcat)
manpagedescription()
bf(FBB:X2a) objects convert values of any (insertable) type to text. The
returned text is automatically made available as a standard bf(C++) string.
includefile(include/namespace)
manpagesection(INHERITS FROM)
bf(std::ostringstream)
manpagesection(CONSTRUCTORS)
itemization(
itb(X2a(T const &value))
In this constructor tt(T) may be any type that can be inserted into an
tt(o[string]stream).
itb(X2a(double value, size_t behind))
Double tt(value) is truncated to tt(behind) digits behind the decimal
dot. If a value doesn't occupy tt(behind) digits behind the decimal point,
then missing digits are added as tt(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.
itb(X2a(double value, size_t width, size_t behind, std::ios::fmtflags
flags = std::ios::right))
The value is displayed over tt(width) character positions, extending
the amount if the value so requires. The converted value is placed
right-aligned into the field of tt(width) characters.
)
The copy constructor is available as well.
manpagesection(STATIC MEMBER FUNCTION)
itemization(
itb(bool lastFail())
This member returns tt(true) if the last conversion failed (i.e., the
object's tt(fail()) member returned tt(true) and returns tt(false) otherwise).
This member allows checks on the success of the extraction/conversion using
anonymous tt(A2x) objects. The member also returns tt(true) when no
conversions have as yet been performed.nl()
Note that this member is a thread-unsafe em(static) member: in a
multithreaded program locks may be required to ensure that the proper
conversion result is inspected.
)
manpagesection(MEMBER FUNCTIONS)
All members of bf(std::ostringstream) are
available, as bf(FBB::X2a) inherits from this class. In particular
tt(ostringstream::str()) can be used to obtain the contents of an tt(X2a)
object's text buffer.
manpagesection(OVERLOADED OPERATORS)
itemization(
itb(operator std::ostream &operator<<(std::ostream &ostr, X2a const &x2a))
This conversion operator inserts the textual representation of the
tt(x2a) parameter value into the provided tt(ostream).
itb(operator std::string const() const)
this conversion operator returns the information stored inside the
bf(FBB::X2a) object.
)
The standard overloaded assignment operator is available as well.
manpagesection(EXAMPLE)
verb(
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.
)
manpagefiles()

manpagebugs()
None Reported.
