The class providing the scrapbook to fill with results of local integration. Depending on the task the mesh worker loop is performing, local results can be of different types. They have in common that they are the result of local integration over a cell or face. Their actual type is determined by the Assember using them. It is also the assembler setting the arrays of local results to the sizes needed. Here is a list of the provided data types and the assembers using them:
n_values() numbers accessed with value(), and stored in the data member J.
false. These are stored in M1, and they are the matrices coupling degrees of freedom in the same cell. For fluxes across faces, there is an additional set M2 of matrices of the same size, but the dimension of the matrices being according to the degrees of freedom on both cells. These are accessed with matrix(), using the second argument true. The local matrices initialized by reinit() of the info object and then assembled into the global system by Assembler classes.
