# \_\_gnu\_pbds::sample\_trie\_access\_traits(3cxx)

A sample trie element access traits.

## NAME

\_\_gnu\_pbds::sample\_trie\_access\_traits - A sample trie element access traits.

## SYNOPSIS

`#include <sample_trie_access_traits.hpp>`

### Public Types

enum { **max\_size** }\
 typedef std::string::const\_iterator **const\_iterator**\
 typedef char **e\_type**\
 Element type.  typedef rebind\_traits\< \_Alloc, **key\_type** \>::const\_reference **key\_const\_reference**\
 typedef **std::string** **key\_type**\
 typedef std::size\_t **size\_type**\

### Static Public Member Functions

static const\_iterator **begin** (key\_const\_reference)\
 Returns a const\_iterator to the first element of r\_key.  static size\_type **e\_pos** (**e\_type**)\
 Maps an element to a position.  static const\_iterator **end** (key\_const\_reference)\
 Returns a const\_iterator to the after-last element of r\_key.
