template<typename _BiIter>class std::sub_match< _BiIter >

A sequence of characters matched by a particular marked sub-expression.

An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression.

The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

template<typename _BiIter> int \fBstd::sub_match\fP< _BiIter >::compare (const \fBsub_match\fP< _BiIter > &__s) const\fC [inline]\fP

Compares this and another matched sequence.

Parameters:

__s Another matched sequence to compare to this one.

Return values:

<0 this matched sequence will collate before __s.

=0 this matched sequence is equivalent to __s.

<0 this matched sequence will collate after __s.

template<typename _BiIter> int \fBstd::sub_match\fP< _BiIter >::compare (const \fBstring_type\fP &__s) const\fC [inline]\fP

Compares this sub_match to a string.

Parameters:

__s A string to compare to this sub_match.

Return values:

<0 this matched sequence will collate before __s.

=0 this matched sequence is equivalent to __s.

<0 this matched sequence will collate after __s.

template<typename _BiIter> int \fBstd::sub_match\fP< _BiIter >::compare (const value_type *__s) const\fC [inline]\fP

Compares this sub_match to a C-style string.

Parameters:

__s A C-style string to compare to this sub_match.

Return values:

<0 this matched sequence will collate before __s.

=0 this matched sequence is equivalent to __s.

<0 this matched sequence will collate after __s.

template<typename _BiIter> difference_type \fBstd::sub_match\fP< _BiIter >::length () const\fC [inline]\fP

Gets the length of the matching sequence.

Definition at line 853 of file regex.h.

template<typename _BiIter> \fBstd::sub_match\fP< _BiIter >::operator \fBstring_type\fP () const\fC [inline]\fP

Gets the matching sequence as a string.

Returns:

the matching sequence as a string.

This is the implicit conversion operator. It is identical to the str() member function except that it will want to pop up in unexpected places and cause a great deal of confusion and cursing from the unwary.

Definition at line 866 of file regex.h.

template<typename _BiIter> \fBstring_type\fP \fBstd::sub_match\fP< _BiIter >::str () const\fC [inline]\fP

Gets the matching sequence as a string.

Returns:

the matching sequence as a string.
