Detailed Description

template<int size>
struct TRIVertexTwoParticleAccessBuffer< size >

Buffer for frequency interpolation information.

The buffer contains a list of memory offsets (number of elements) in the frequency dimensions of the two-particle vertex that correspond to all the support values that are part of the interpolation. The memory offset in frequency space must be complemented with the linear memory offset in the lattice site dimension. Each support value is assigned a weight factor. Each support value is also complemented by a sign factor that is either +1 or -1 (and depends on the two vertex channel arguments) and by the information whether a lattice site exchange should be performed upon accessing the support value.

Template Parameters

size	Number of support sites for the interpolation.
