template<typename inType = double, typename outType = double>
struct exahype2::FaceData< inType, outType >

Represents the sides of one face, with 2 sides (left and right) to a face For ADER QIn will contain the values, QOut would contain the fluxes QIn[faceId][0][...] will contain the values of the left side relative to the face QIn[faceId][1][...] will contain the values of the right side relative to the face.

Construct patch data object for one single cell.

Usually, I do so only to be able to use the same kernels everywhere: Kernels accept FaceData, i.e. multiple patches. Even if we have only one cell, we thus wrap this cell's data into an instance of FaceData and pass it in. The id can be set to any dummy in this case, as we know which task has wrapped this single cell, i.e. we usually do not read it later.

Required when we fuse many enclave tasks and load them off to the GPU, as we have to know afterwards which outcome corresponds to which task.
