java.lang.Objectorg.apache.commons.collections.primitives.AbstractFloatCollection
org.apache.commons.collections.primitives.RandomAccessFloatList
Abstract base class for FloatLists backed
by random access structures like arrays.
get(int)
and size(). Mutable subclasses
should also override set(int, float). Variably-sized
subclasses should also override add(int, float)
and removeElementAt(int). All other methods
have at least some base implementation derived from
these. Subclasses may choose to override these methods
to provide a more efficient implementation.

public abstract float get(int index)
FloatList
get in interface FloatListindex - the index of the element to return
public abstract int size()
FloatCollection
size in interface FloatCollectionsize in class AbstractFloatCollectionpublic float removeElementAt(int index)
removeElementAt in interface FloatListindex - the index of the element to remove
java.lang.UnsupportedOperationException - since this method is not supported
public float set(int index,
float element)
set in interface FloatListindex - the index of the element to changeelement - the value to be stored at the specified position
java.lang.UnsupportedOperationException - since this method is not supported
public void add(int index,
float element)
add in interface FloatListindex - the index at which to insert the elementelement - the value to insert
java.lang.UnsupportedOperationException - since this method is not supportedpublic boolean add(float element)
FloatListtrue
iff I changed as a result of this call.
If a collection refuses to add the specified
element for any reason other than that it already contains
the element, it must throw an exception (rather than
simply returning false). This preserves the invariant
that a collection always contains the specified element after
this call returns.
add in interface FloatListadd in class AbstractFloatCollection
public boolean addAll(int index,
FloatCollection collection)
FloatListiterator.
addAll in interface FloatListindex - the index at which to insert the first element from
the specified collectioncollection - the FloatCollection of elements to add
true iff I changed as a result of this callpublic int indexOf(float element)
FloatList-1 if I do not contain
the element.
indexOf in interface FloatListelement - the element to search for
-1 if no such matching element can be foundpublic int lastIndexOf(float element)
FloatList
lastIndexOf in interface FloatListelement - the element to search for
-1 if no such matching element can be foundpublic FloatIterator iterator()
FloatListiterator over all my elements,
in the appropriate sequence.
iterator in interface FloatListiterator in class AbstractFloatCollectionpublic FloatListIterator listIterator()
FloatListbidirectional iterator
over all my elements, in the appropriate sequence.
listIterator in interface FloatListpublic FloatListIterator listIterator(int index)
FloatListbidirectional iterator
over all my elements, in the appropriate sequence,
starting at the specified position. The
specified index indicates the first
element that would be returned by an initial
call to the
next
method. An initial call to the
previous
method would return the element with the specified
index minus one.
listIterator in interface FloatList
public FloatList subList(int fromIndex,
int toIndex)
FloatListFloatList
is backed by me, so that any changes in
the returned list are reflected in me, and vice-versa.
The returned list supports all of the optional operations
that I support.
Note that when fromIndex == toIndex,
the returned list is initially empty, and when
fromIndex == 0 && toIndex == size()
the returned list is my "improper" sublist, containing all my elements.
The semantics of the returned list become undefined
if I am structurally modified in any way other than
via the returned list.
subList in interface FloatListfromIndex - the smallest index (inclusive) in me that appears in
the returned listtoIndex - the largest index (exclusive) in me that appears in the
returned list
public boolean equals(java.lang.Object that)
FloatListtrue iff that is an FloatList
that contains the same elements in the same order as me.
In other words, returns true iff that is
an FloatList that has the same size as me,
and for which the elements returned by its
iterator are equal (==) to
the corresponding elements within me.
(This contract ensures that this method works properly across
different implementations of the FloatList interface.)
equals in interface FloatListpublic int hashCode()
FloatListFloatList is defined to be the
result of the following calculation:
int hash = 1;
for(FloatIterator iter = iterator(); iter.hasNext(); ) {
float value = iter.next();
hash = 31*hash + (int)(value ^ (value >>> 32));
}
This contract ensures that this method is consistent with
equals and with the
hashCode
method of a List of Floats.
