87 /// @brief Generic Attribute Interface class to get/set data as index
88 /// pairs.
89 ///
90 /// This class provides an interface to access attribute data. Each
91 /// attribute type may provide this interface if it makes sense.
92 ///
93 /// Index pair data can also contain a set of primary objects corresponding to
94 /// the indices. These objects should be used to hold information about the
95 /// capture region for the associated index. If the object contains a string
96 /// property, it should be unique (eg. capture path). Use s=0 to manipulate
97 /// primary objects. For example:
98 /// @code
99 /// // create primary object set
100 /// aif->setObjectSetCount(attrib, 1);
101 /// const GA_AIFIndexPairObjects *objects = aif->setObjects(attrib);
102 /// // create a string property for the objects called "path"
103 /// UT_StringArray sdef;
104 /// sdef.append("");
105 /// objects->addProperty("path", sdef);
106 /// // create a float16 property for the objects called "transform"
107 /// UT_FloatArray fdef;
108 /// for(int i = 0; i < 16; ++i)
109 /// fdef.append((i % 5 == 0) ? 1.0 : 0.0);
110 /// objects->addProperty("transform", fdef);
111 /// // add a new object
112 /// objects->setObjectCount(1);
113 /// @endcode
114 ///
115 /// Index pair data can also contain a secondary set of objects for holding
116 /// multiple bits of subdata per index. These objects should be used to hold
117 /// supplimentary data about objects such as the individual metaballs that make
118 /// up a muscle. These secondary objects should also contain an integer
119 /// property identifying the index of the primary object. Use s>0 to
120 /// manipulate secondary objects.
