- Direct Known Subclasses:
public class StaticBin1D extends AbstractBin1D1-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
DynamicBin1D, 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.

public void add(double element)Adds the specified element to the receiver.
public void addAllOfFromTo(DoubleArrayList list, int from, int to)Adds the part of the specified list between indexes from (inclusive) and to (inclusive) to the receiver.
list- the list of which elements shall be added.
from- the index of the first element to be added (inclusive).
to- the index of the last element to be added (inclusive).
IndexOutOfBoundsException- if list.size()>0 && (from<0 || from>to || to>=list.size()).
public void clear()Removes all elements from the receiver. The receiver will be empty after this call returns.
public boolean isRebinnable()Returns false. Returns whether a client can obtain all elements added to the receiver. In other words, tells whether the receiver internally preserves all added elements. If the receiver is rebinnable, the elements can be obtained via elements() methods.
public int size()Returns the number of elements contained in the receiver.
public double sum()Returns the sum of all elements, which is Sum( x[i] ).
