◆ getNumberOfGlobalComponents()

int ParameterLib::TimeDependentHeterogeneousParameter::getNumberOfGlobalComponents ( ) const

overridevirtual

Returns the number of components this Parameter has at every position and point in time.

Implements ParameterLib::Parameter< double >.

Definition at line 28 of file TimeDependentHeterogeneousParameter.cpp.

{
    return _time_parameter_mapping[0].second->getNumberOfGlobalComponents();
}

References _time_parameter_mapping, and ParameterLib::Parameter< T >::getNumberOfGlobalComponents().

◆ initialize()

void ParameterLib::TimeDependentHeterogeneousParameter::initialize ( std::vector< std::unique_ptr< ParameterBase > > const & parameters )

overridevirtual

The TimeDependentHeterogeneousParameter depends in each time step on a parameter. Since, at construction time of the TimeDependentHeterogeneousParameter other parameter needs not to be constructed and hence can't be used to setup the object this is done later on in the initialize method.

Reimplemented from ParameterLib::ParameterBase.
