Detailed Description

Abstract base class for array dimension tags supplied to the Array template class.

A derived array dimension tag class must provide the name method and tag singleton method as in the following example.

struct MyTag : public shards::ArrayDimTag {
  const char * name() const ;
  static const MyTag & tag();
};

An example implementation of these methods is as follows.

const char * MyTag::name() const
{ static const char my_name[] = "MyTag" ; return my_name ; }

const MyTag & MyTag::tag()
{ static const MyTag my_tag ; return my_tag ; }
