Detailed Description

template<typename RealType>
class UE::Solvers::TSparseMatrixAssembler< RealType >

Generic adapter for building a Sparse Matrix. Generally sparse-matrix assembly code emits matrix entries as tuples of form (i,j,Value).

AddEntriesFunc

template<typename RealType >

TUniqueFunction<void(const FTupleData*, int32)> UE::Solvers::TSparseMatrixAssembler< RealType >::AddEntriesFunc

Initial value:

= [this](const FTupleData* DataStart, int32 Num)
            {
                if (!AddEntryFunc)
                {
                    return;
                }
                for (int32 i = 0; i < Num; ++i)
                {
                    const FTupleData& Tuple = DataStart[Num];
                    AddEntryFunc(Tuple.I, Tuple.J, Tuple.Value);
                }
            }

Add matrix entries (i,j,Value) and size of tuples

AddEntryFunc

template<typename RealType >

TUniqueFunction<void(int32, int32, RealType)> UE::Solvers::TSparseMatrixAssembler< RealType >::AddEntryFunc

Add matrix entry tuple (i,j,Value)

ReserveEntriesFunc

template<typename RealType >

TUniqueFunction<void(int32)> UE::Solvers::TSparseMatrixAssembler< RealType >::ReserveEntriesFunc

Hint to reserve space for at least this many entries
