unsigned int | component |
Extractor for a single scalar component of a vector-valued element. The result of applying an object of this type to an FEValues, FEFaceValues or FESubfaceValues object is of type FEValuesViews::Scalar. The concept of extractors is defined in the documentation of the namespace FEValuesExtractors and in the Handling vector valued problems topic.

Default constructor. Initialize the object with an invalid component. This leads to an object that can not be used, but it allows objects of this kind to be put into arrays that require a default constructor upon resizing the array, and then later assigning a suitable object to each element of the array.
