 * @class   vtkInformationQuadratureSchemeDefinitionVectorKey
 * @brief   Key for vtkQuadratureSchemeDefinition vector values.
 *
 * vtkInformationQuadratureSchemeDefinitionVectorKey is used to represent keys for double
 * vector values in vtkInformation.h. NOTE the interface in this key differs
 * from that in other similar keys because of our internal use of smart
 * pointers.
