The type
field provides a function object that extracts a key from the VertexProperty
.
The function object type must have a nested result_type
that provides the type of the key. For more information, see the KeyExtractor
concept in the Boost.MultiIndex documentation: type
must either be void
(if VertexProperty
does not have an internal vertex name) or a model of KeyExtractor
.
