boost::mpl::Bidirectional Sequence

# Bidirectional Sequence

### Description

A Bidirectional Sequence is a Forward Sequence, which provides iterators that satisfy the Bidirectional Iterator requirements.

### Refinement of

Forward Sequence

### Valid expressions

Bidirectional Sequence does not define any new expressions beyond those defined in Forward Sequence. However, it refines the expression requirements.

Expression | Expression type
--- | ---
`typename begin<s>::type` | A model of Bidirectional Iterator
`typename end<s>::type` | A model of Bidirectional Iterator

### Models

- `vector`
- `vector_c`
- `range_c`

### See also
