public class StaticDoubleBin1D
1-dimensional non-rebinnable bin consuming double elements; Efficiently computes basic statistics of data sequences. First see the package summary and javadoc tree view to get the broad picture.
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.
