\typedef igraph_attribute_record_t \brief An attribute record holding the name, type and values of an attribute.

This composite data type is used in the attribute interface to specify a name-type-value triplet where the name is the name of a graph, vertex or edge attribute, the type is the corresponding igraph type of the attribute and the value is a \em vector of attribute values. Note that for graph attributes we use a vector of length 1. The type of the vector depends on the attribute type: it is \ref igraph_vector_t for numeric attributes, \c igraph_strvector_t for string attributes and \c igraph_vector_bool_t for Boolean attributes.

The record also stores default values for the attribute. The default values are used when the value vector of the record is resized with \ref igraph_attribute_record_resize(). It is important that the record stores \em one default value only, corresponding to the type of the attribute record. The default value is \em cleared when the type of the record is changed.
