Detailed Description
template<typename T>
class Hermes::Hermes2D::DiscontinuousFunc< T >
This class represents a function with jump discontinuity on an interface of two elements.
We will refer to one of the elements sharing the interface of discontinuity as to the central element, while to the other one as to the neighbor element.
Instance of the class may be constructed either with two Func objects, which represent the continuous components on the central and the neighbor element, respectively, or with only one Func object and information about its support (where it attains non-zero value). The discontinuous function is in the latter case constructed by extending the supplied function by zero to the other element. Values and derivatives from both elements may then be obtained by querying the corresponding Func object, using methods get_val_central, get_val_neighbor, etc.
