Should always be used if more than 50% of the data is sparse. As fast (or even faster than map implementation) but needs considerably less memory. This implementation uses byte arrays instead of double arrays which will reduce the used memory even more.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: ByteSparseArrayDataRow.java,v 1.3 2008/05/09
