AbstractDoubleBin (Parallel Colt 0.10.1

java.lang.Object
- cern.colt.PersistentObject
- - hep.aida.tdouble.bin.AbstractDoubleBin

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

AbstractDoubleBin1D
```
public abstract class AbstractDoubleBin
extends PersistentObject
```
Abstract base class for all arbitrary-dimensional bins consumes double elements. First see the package summary and javadoc tree view to get the broad picture.
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.

Method Summary

Methods
Modifier and Type	Method and Description
`double`	`center()` Returns `center(0)`.
`double`	`center(int dimension)` Returns a custom definable "center" measure; override this method if necessary.
`abstract void`	`clear()` Removes all elements from the receiver.
`boolean`	`equals(Object otherObj)` Returns whether two objects are equal; This default implementation returns true if the other object is a bin and has the same size, value, error and center.
`double`	`error()` Returns `error(0)`.
`double`	`error(int dimension)` Returns a custom definable error measure; override this method if necessary.
`abstract boolean`	`isRebinnable()` Returns whether a client can obtain all elements added to the receiver.
`double`	`offset()` Returns `offset(0)`.
`double`	`offset(int dimension)` Returns the relative or absolute position for the center of the bin; override this method if necessary.
`abstract int`	`size()` Returns the number of elements contained.
`String`	`toString()` Returns a String representation of the receiver.
`void`	`trimToSize()` Trims the capacity of the receiver to be the receiver's current size.
`double`	`value()` Returns `value(0)`.
`double`	`value(int dimension)` Returns a custom definable "value" measure; override this method if necessary.

- Method Detail
  - center
```
public final double center()
```
    Returns center(0).
  - center
```
public double center(int dimension)
```
    Returns a custom definable "center" measure; override this method if necessary. Returns the absolute or relative center of this bin. For example, the center of gravity. The real absolute center can be obtained as follow: partition(i).min(j) * bin(j).offset() + bin(j).center(i), where i is the dimension. and j is the index of this bin.
    This default implementation always returns 0.5.
    
    Parameters:
    dimension - the dimension to be considered (zero based).
  - clear
```
public abstract void clear()
```
    Removes all elements from the receiver. The receiver will be empty after this call returns.
  - equals
```
public boolean equals(Object otherObj)
```
    Returns whether two objects are equal; This default implementation returns true if the other object is a bin and has the same size, value, error and center.
    
    Overrides:
    
    equals in class Object
  - error
```
public final double error()
```
    Returns error(0).
  - error
```
public double error(int dimension)
```
    Returns a custom definable error measure; override this method if necessary. This default implementation always returns 0.
    
    Parameters:
    dimension - the dimension to be considered.
  - isRebinnable
```
public abstract boolean isRebinnable()
```
    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.
  - offset
```
public final double offset()
```
    Returns offset(0).
  - offset
```
public double offset(int dimension)
```
    Returns the relative or absolute position for the center of the bin; override this method if necessary. Returns 1.0 if a relative center is stored in the bin. Returns 0.0 if an absolute center is stored in the bin.
    This default implementation always returns 1.0 (relative).
    
    Parameters:
    dimension - the index of the considered dimension (zero based);
  - size
```
public abstract int size()
```
    Returns the number of elements contained.
    
    Returns:
    the number of elements contained.
  - toString
```
public String toString()
```
    Returns a String representation of the receiver.
    
    Overrides:
    
    toString in class Object
  - trimToSize
```
public void trimToSize()
```
    Trims the capacity of the receiver to be the receiver's current size. Releases any superfluos internal memory. An application can use this operation to minimize the storage of the receiver. This default implementation does nothing.
  - value
```
public final double value()
```
    Returns value(0).
  - value
```
public double value(int dimension)
```
    Returns a custom definable "value" measure; override this method if necessary.
    This default implementation always returns 0.0.
    
    Parameters:
    dimension - the dimension to be considered.
