Constructor & Destructor Documentation

FEValuesExtractors::Scalar::Scalar ( )

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.

FEValuesExtractors::Scalar::Scalar ( const unsigned int  component)

Constructor. Take the selected vector component as argument.
