[in] | _prm | Parameter class for this local operator |
[in] | _superintegration_order | This number will be added to the order of quadrature in every integration. It is only needed, when one of the parameters (e.g rho, mu) is not constant or the mappings from the reference elements to the cells are nonlinear. Boundary conditions are assumed to have the same order as the corresponding finite element. |

set time for subsequent evaluation
This method set the time for subsequent calls to the alpha_*(), lambda_*(), jacobian_*() and jacobian_apply_*() methods.

to be called after stage 1
This may be called on the spatial local operator in the case of an explicit one step scheme. It is called after stage 1 has been assembled (so the time given to preStep() may not apply anymore in this case). All the alpha_*() and lambda_*() methods should have been called, so they are a good place to generate the information returned here.
