public class StaticDoubleBin1D extends AbstractDoubleBin1D
The data streamed into a SimpleBin1D is not preserved! As a
consequence infinitely many elements can be added to this bin. As a further
consequence this bin cannot compute more than basic statistics. It is also
not rebinnable. If these drawbacks matter, consider to use a
DynamicDoubleBin1D, which overcomes them at the expense of increased
memory requirements.
This class is fully thread safe (all public methods are synchronized). Thus, you can have one or more threads adding to the bin as well as one or more threads reading and viewing the statistics of the bin while it is filled. For high performance, add data in large chunks (buffers) via method addAllOf rather than piecewise via method add.
Implementation: Incremental maintainance. Performance linear in the number of elements added.
