◆ swap()

void SharedOffset::swap ( const std::vector< std::size_t > & component_keys )

When calculating an unbinned likelihood with square weights applied, a different offset is necessary.

Similar situations may ask for a separate offset as well. This function switches between the two sets of offset values for the given component keys.

Note: Currently we do not recalculate the offset value, so in practice swapped offsets are zero.
