Method Summary

Modifier and Type	Method	Description
long	toColumnIndex(C columnKey)
C	toColumnKey(long index)
long	toIndex(Structure2D.RowColumnKey<R,C> key)	For each key (any instance of that type) there is a corresponding index value – 1 or more key instances will be mapped to each index value.
long	toIndex(R rowKey, C colKey)
Structure2D.RowColumnKey<R,C>	toKey(long index)	In most cases it should be safe to assume that the input index value is valid (matching what would be created by Structure1D.IndexMapper.toIndex(Object)).
long	toRowIndex(R rowKey)
R	toRowKey(long index)
