A Property type is a type used to name or identify properties that are
|
|
attached to the vertices and edges of a graph. A Property type is not
|
|
the type of the actual property values. Objects of the Property type
|
|
are not used except to carry the type information which specifies the
|
|
property.
|
|
|
|
<h3>Associated Types</h3>

<tr>
|
|
<td>Property Kind </td>
|
|
<td><TT>property_kind<Property>::type</TT> </td>
|
|
<td>
|
|
|
|
This specifies whether the property is a <a
|
|
name="VertexProperty">VertexProperty</a>
|
|
(<tt>vertex_property_tag</tt>), an <a
|
|
name="EdgeProperty">EdgeProperty</a> (<tt>edge_property_tag</tt>), or
|
|
a <a name="GraphProperty">GraphProperty</a> which is attached to the
|
|
graph object itself (<tt>graph_property_tag</tt>). The tags are
|
|
defined in <a
|
|
href="../../../boost/graph/properties.hpp"><tt>boost/graph/properties.hpp</tt></a>

<h3>Models</h3>

The following models of the Property concept are defined
|
|
in <a

|
|
|
|
<ul>
|

<h3>Notes</h3>
|
|
|
|
On compilers that do not support partial specialization, each Property
|
|
type is also required to specialize
|
|
<tt>property_num<Property></tt> to contain an enum named
|
|
<tt>value</tt> which uniquely identifies the property type.
