This procedure assumes that you have control over the types that should
be made conformant to a Range concept. If not, see < a class = "link" href = "method_2.html" title = "Method 2: provide free-standing functions and specialize metafunctions" > method
2</ a > .

< p >
The primary templates in this library are implemented such that standard
2010-04-05 17:36:10 +00:00
containers will work automatically and so will < a href = "../../../../../../../libs/array/index.html" target = "_top" > boost::array</ a > .

Below is given an overview of which member functions and member types a
class must specify to be useable as a certain Range concept.

</ tr ></ thead >
< tbody >

< td >
< p >
< code class = "computeroutput" >< span class = "identifier" > begin</ span >< span class = "special" > ()</ span ></ code >
</ p >
</ td >
< td >
< p >
< a class = "link" href = "../../concepts/single_pass_range.html" title = "Single Pass Range" > Single Pass
Range</ a >
</ p >
</ td >
</ tr >
< tr >
< td >
< p >
< code class = "computeroutput" >< span class = "identifier" > end</ span >< span class = "special" > ()</ span ></ code >
</ p >
</ td >
< td >
< p >
< a class = "link" href = "../../concepts/single_pass_range.html" title = "Single Pass Range" > Single Pass
Range</ a >
</ p >
</ td >
</ tr >
</ tbody >
</ table ></ div >
< p >
Notice that < code class = "computeroutput" >< span class = "identifier" > rbegin</ span >< span class = "special" > ()</ span ></ code >
and < code class = "computeroutput" >< span class = "identifier" > rend</ span >< span class = "special" > ()</ span ></ code >
member functions are not needed even though the container can support bidirectional
iteration.
</ p >
< p >
The required member types are:
</ p >
< div class = "informaltable" >< table class = "table" >
< colgroup >
< col >
< col >
</ colgroup >
< thead >< tr >
< th >
< p >

< th >

</ th >
</ tr ></ thead >
< tbody >
< tr >
< td >
< p >
< code class = "computeroutput" >< span class = "identifier" > iterator</ span ></ code >
</ p >
</ td >
< td >
< p >
< a class = "link" href = "../../concepts/single_pass_range.html" title = "Single Pass Range" > Single Pass
Range</ a >
</ p >
</ td >
</ tr >
< tr >
< td >
< p >
< code class = "computeroutput" >< span class = "identifier" > const_iterator</ span ></ code >
</ p >
</ td >
< td >
< p >
< a class = "link" href = "../../concepts/single_pass_range.html" title = "Single Pass Range" > Single Pass
Range</ a >
</ p >
</ td >
</ tr >
</ tbody >
</ table ></ div >
< p >
Again one should notice that member types < code class = "computeroutput" >< span class = "identifier" > reverse_iterator</ span ></ code >
and < code class = "computeroutput" >< span class = "identifier" > const_reverse_iterator</ span ></ code >
are not needed.
