Detailed Description

Function Documentation

template<typename MT , bool SO>
void clear ( SparseRow< MT, SO > &  row)
inlineprivate

Clearing the given sparse row.

Parameters
rowThe sparse row to be cleared.
Returns
void

Clearing a sparse row is equivalent to resetting it via the reset() function.

template<typename MT , bool SO>
bool isDefault ( const SparseRow< MT, SO > &  row)
inlineprivate

Returns whether the given sparse row is in default state.

Parameters
rowThe sparse row to be tested for its default state.
Returns
true in case the given row is component-wise zero, false otherwise.

This function checks whether the sparse row is in default state. For instance, in case the row is instantiated for a built-in integral or floating point data type, the function returns true in case all row elements are 0 and false in case any vector element is not 0. The following example demonstrates the use of the isDefault function:

// ... Resizing and initialization
if( isDefault( row( A, 0UL ) ) ) { ... }
template<typename MT , bool SO>
void reset ( SparseRow< MT, SO > &  row)
inlineprivate

Resetting the given sparse row.

Parameters
rowThe sparse row to be resetted.
Returns
void
