FloatCollectionToCollectionAdapter
public class FloatCollectionToCollectionAdapter extends AbstractCollection (Code)
This class represents adaptions of primitive collections of float values to Java Collections Framework collections. The adapter is implemented as a wrapper around a primitive collection. Thus, changes to the underlying collection are reflected by this collection and vice versa.

Field Summary
protected  FloatCollectioncollection
     The underlying primitive collection.

Constructor Summary
public  FloatCollectionToCollectionAdapter(FloatCollection collection)
     Creates a new adaption of a collection of float values to a Java Collections Framework collection.

Method Summary
public  booleanadd(Object o)
     Adds an element to this collection.
public  voidclear()
     Clears this collection.
public  booleancontains(Object o)
     Indicates whether this collection contains a specified element.
public  inthashCode()
     Returns a hash code value for this collection.
public  Iteratoriterator()
     Returns an iterator over this collection.
public  booleanremove(Object o)
     Removes a specified element from this collection. The unwrapped element is removed from the underlying collection.

Note that this collection can never contain null values or values of other classes than Float Float . In those cases, this method will return false.
Parameters:
  o - the Float value to remove from this collection.

public  booleanremoveAll(Collection c)
     Removes all the elements of a specified collection from this collection.
public  booleanretainAll(Collection c)
     Retains only the elements of a specified collection in this collection.
public  intsize()
     Returns the number of elements in this collection.

Field Detail
collection
protected FloatCollection collection(Code)
The underlying primitive collection.




Constructor Detail
FloatCollectionToCollectionAdapter
public FloatCollectionToCollectionAdapter(FloatCollection collection)(Code)
Creates a new adaption of a collection of float values to a Java Collections Framework collection.
Parameters:
  collection - the underlying primitive collection.
throws:
  NullPointerException - if collection is null.




Method Detail
add
public boolean add(Object o)(Code)
Adds an element to this collection. The element is added to the underlying collection.
Parameters:
  o - the element to add to this collection. true if this collection was modifiedas a result of adding o; returnsfalse otherwise.
throws:
  IllegalArgumentException - if o is null.
throws:
  ClassCastException - if o is not of class Float Float.
throws:
  UnsupportedOperationException - if the operation is not supported by theunderlying collection.



clear
public void clear()(Code)
Clears this collection. The underlying collection is cleared.
throws:
  UnsupportedOperationException - if the operation is not supported by theunderlying collection.



contains
public boolean contains(Object o)(Code)
Indicates whether this collection contains a specified element. For this collection to contain an object, the underlying collection must contain its unwrapped value.

Note that this collection can never contain null values or values of other classes than Float Float . In those cases, this method will return false.
Parameters:
  o - the element to test for containment. true if o is contained in thiscollection; returns false otherwise.




hashCode
public int hashCode()(Code)
Returns a hash code value for this collection. The hash code returned is that of the underlying collection. a hash code value for this collection.



iterator
public Iterator iterator()(Code)
Returns an iterator over this collection. an iterator over this collection.



remove
public boolean remove(Object o)(Code)
Removes a specified element from this collection. The unwrapped element is removed from the underlying collection.

Note that this collection can never contain null values or values of other classes than Float Float . In those cases, this method will return false.
Parameters:
  o - the Float value to remove from this collection. true if this collection was modifiedas a result of removing o; returnsfalse otherwise.
throws:
  UnsupportedOperationException - if the operation is not supported by the underlying collection.




removeAll
public boolean removeAll(Collection c)(Code)
Removes all the elements of a specified collection from this collection. The unwrapped elements are removed from the underlying collection.

This method is only overridden to work around a bug in AbstractCollection AbstractCollection , which does not throw a NullPointerException NullPointerException when the argument is null and the collection is empty.
Parameters:
  c - the collection whose elements to remove from thiscollection. true if this collection was modifiedas a result of removing the elements of c;returns false otherwise.
throws:
  UnsupportedOperationException - if the operation is not supported by the underlyingcollection.
throws:
  NullPointerException - if c is null.




retainAll
public boolean retainAll(Collection c)(Code)
Retains only the elements of a specified collection in this collection. The unwrapped elements are removed from the underlying collection.

This method is only overridden to work around a bug in AbstractCollection AbstractCollection , which does not throw a NullPointerException NullPointerException when the argument is null and the collection is empty.
Parameters:
  c - the collection whose elements to retain in thiscollection. true if this collection was modifiedas a result of removing the elements not containedin c;returns false otherwise.
throws:
  UnsupportedOperationException - if the operation is not supported by the underlyingcollection.
throws:
  NullPointerException - if c is null.




size
public int size()(Code)
Returns the number of elements in this collection. The number of elements is the same as that of the underlying collection. the number of elements in this collection.
