FBB::StringLine(3) extracting lines using operator>>

SYNOPSIS

#include <bobcat/stringline>

DESCRIPTION

The standard operator>>(std::istream &, std::string &) string extracion operator extracts the first `word' from a stream. In cases where the intent it to extract lines from the stream this operator cannot be used, but getline(std::istream &, std::string &) is usually called.

However, getline is not called by many tools of generic algorithms, like the istream_iterator.

The class (actually: struct) StringLine was simply derived from std::string, and defines its own operator>>, reading the next line from the specified std::istream.

NAMESPACE

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

INHERITS FROM

std::string

CONSTRUCTORS

StringLine is an empty shell around std::string. It does not explicitly define constructors. The default and copy constructors are available.

OVERLOADED OPERATOR

  • std::istream &operator>>(std::istream &in, StringLine &str):
    The extraction operator returns the next line on in in str, calling getline(std::istream &, std::string &).

MEMBER FUNCTIONS

All members of std::string are available, as FBB::StringLine inherits from these classes.

EXAMPLE

The following example extracts all lines from std::cin and adds them to the std::vector<std::string> lines:
#include <iostream>
#include <algorithm>
#include <iterator>
#include <vector>
#include <bobcat/stringline>
using namespace std;
using namespace FBB;
int main()
{
    vector<string> lines;
    
    copy(
        istream_iterator<StringLine>(cin), istream_iterator<StringLine>(), 
        back_inserter(lines)
    );
}
        

FILES

bobcat/stringline - defines the class interface and operator>>.

There are StringLine object files in the Bobcat library, so linking to Bobcat when using StringLine is not necessary.

BUGS

None Reported.
