Shared Array Property Map

##

    shared_array_property_map<ValueType, OffsetMap>

This property map is an adaptor that contains a boost::shared_array and uses that array to store the property map's data. The resulting property map is a model of Lvalue Property Map. The `OffsetMap` type is responsible for converting key objects to integers that can be used as offsets into the array.

### Where Defined

`boost/property_map/shared_array_property_map.hpp`

### Model Of

Lvalue Property Map

### Template Parameters

Parameter | Description | Default
--- | --- | ---
`ValueType` | The value type of the property map. |
`OffsetMap` | Must be a model of Readable Property Map and the value type must be convertible to `std::size_t`. |

### Members

In addition to the methods and functions required by Lvalue Property Map, this class has the following members.

    property_traits<shared_array_property_map>::value_type

This is the same type as `ValueType`.

    shared_array_property_map(size_t n)

Constructor. Builds the property map with a size of `n` elements. The `OffsetMap` is default constructed.

    shared_array_property_map(size_t n, OffsetMap m)

Constructor. Builds the property map with a size of `n` elements.

### Non-Member functions

      template <class ValueType, class OffsetMap>
      shared_array_property_map<ValueType, OffsetMap>
      make_shared_array_property_map(size_t n, const ValueType&, OffsetMap omap)

A function for conveniently creating a shared array map.
