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

ParameterDescriptionDefault
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.
