.. cpp:class:: PointIntegralSolver

    *Parent class(es)*
    
        * :cpp:class:`Variable`
        
    This class is a time integrator for general Runge Kutta forms
    It only includes Point integrals with piecewise linear test
    functions. Such problems are disconnected at the vertices and
    can therefore be solved locally.


    .. cpp:function:: explicit PointIntegralSolver(std::shared_ptr<MultiStageScheme> scheme)
    
        Constructor
        FIXME: Include version where one can pass a Solver and/or
        Parameters


    .. cpp:function:: void step(double dt)
    
        Step solver with time step dt


    .. cpp:function:: void step_interval(double t0, double t1, double dt)
    
        Step solver an interval using dt as time step


    .. cpp:function:: std::shared_ptr<MultiStageScheme> scheme() const
    
        Return the MultiStageScheme


    .. cpp:function:: static Parameters default_parameters()
    
        Default parameter values


    .. cpp:function:: void reset_newton_solver()
    
        Reset newton solver


    .. cpp:function:: void reset_stage_solutions()
    
        Reset stage solutions


    .. cpp:function:: std::size_t num_jacobian_computations() const
    
        Return number of computations of jacobian
