Detailed Description

template<class ParameterImpl>
class Dune::ACFem::ParameterInterface< ParameterImpl >

Parameters are quasi-constant quantities, like the time-step size in one time-step when solving transient problems with finite element methods.

One of their purpose is to inject such parameters into expression-templates without losing access to the parameter. Good examples are the TimeStepParameter and InverseTimeStepParameter classes.

value()

ValueType Dune::ACFem::ParameterInterface< ParameterImpl >::value ( ) const

inline

Return the current value of the parameter.

The value is always returned as a copy. Parameters are intentionally scalars or (very) small Dune::FieldVector classes, although this is not defined by the interface.
