Method Detail

wrap

public static final org.apache.commons.collections.primitives.FloatList wrap(org.apache.commons.collections.primitives.FloatList list)

add

public final void add(int index,
                      float element)

Description copied from interface: FloatList

Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.

Specified by:

add in interface FloatList

Overrides:

add in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

Parameters:

index - the index at which to insert the element

element - the value to insert

addAll

public final boolean addAll(int index,
                            org.apache.commons.collections.primitives.FloatCollection collection)

Description copied from interface: FloatList

Inserts all of the elements in the specified collection into me, at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices. The new elements will appear in the order that they are returned by the given collection's iterator.

Specified by:

addAll in interface FloatList

Overrides:

addAll in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

Parameters:

index - the index at which to insert the first element from the specified collection

collection - the FloatCollection of elements to add

Returns:

true iff I changed as a result of this call

removeElementAt

public final float removeElementAt(int index)

Description copied from interface: FloatList

Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.

Specified by:

removeElementAt in interface FloatList

Overrides:

removeElementAt in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

Parameters:

index - the index of the element to remove

Returns:

the value of the element that was removed

set

public final float set(int index,
                       float element)

Description copied from interface: FloatList

Replaces the element at the specified position in me with the specified element (optional operation).

Specified by:

set in interface FloatList

Overrides:

set in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

Parameters:

index - the index of the element to change

element - the value to be stored at the specified position

Returns:

the value previously stored at the specified position

add

public final boolean add(float element)

Description copied from interface: FloatList

Appends the specified element to the end of me (optional operation). Returns true 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.

Specified by:

add in interface FloatList

Overrides:

add in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Parameters:

element - the value whose presence within me is to be ensured

Returns:

true iff I changed as a result of this call

addAll

public final boolean addAll(org.apache.commons.collections.primitives.FloatCollection c)

Description copied from interface: FloatCollection

Adds all of the elements in the specified collection to me (optional operation).

Specified by:

addAll in interface FloatCollection

Overrides:

addAll in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Parameters:

c - the collection of elements whose presence within me is to be ensured

Returns:

true iff I changed as a result of this call

clear

public final void clear()

Description copied from interface: FloatCollection

Removes all my elements (optional operation). I will be empty after this method successfully returns.

Specified by:

clear in interface FloatCollection

Overrides:

clear in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

removeAll

public final boolean removeAll(org.apache.commons.collections.primitives.FloatCollection c)

Description copied from interface: FloatCollection

Removes all of my elements that are contained in the specified collection (optional operation). The behavior of this method is unspecified if the given collection is modified while this method is executing. Note that this includes the case in which the given collection is this collection, and it is not empty.

Specified by:

removeAll in interface FloatCollection

Overrides:

removeAll in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Parameters:

c - the collection of elements to remove

Returns:

true iff I contained the at least one of the specified elements, in other words, returns true iff I changed as a result of this call

removeElement

public final boolean removeElement(float element)

Description copied from interface: FloatCollection

Removes a single occurrence of the specified element (optional operation).

Specified by:

removeElement in interface FloatCollection

Overrides:

removeElement in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Parameters:

element - the element to remove, if present

Returns:

true iff I contained the specified element, in other words, iff I changed as a result of this call

retainAll

public final boolean retainAll(org.apache.commons.collections.primitives.FloatCollection c)

Description copied from interface: FloatCollection

Removes all of my elements that are not contained in the specified collection (optional operation). (In other words, retains only my elements that are contained in the specified collection.) The behavior of this method is unspecified if the given collection is modified while this method is executing.

Specified by:

retainAll in interface FloatCollection

Overrides:

retainAll in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Parameters:

c - the collection of elements to retain

Returns:

true iff I changed as a result of this call

subList

public final org.apache.commons.collections.primitives.FloatList subList(int fromIndex,
                                                                         int toIndex)

Description copied from interface: FloatList

Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. The returned FloatList 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.

Specified by:

subList in interface FloatList

Overrides:

subList in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

Parameters:

fromIndex - the smallest index (inclusive) in me that appears in the returned list

toIndex - the largest index (exclusive) in me that appears in the returned list

Returns:

a view of this list from fromIndex (inclusive) to toIndex (exclusive)

iterator

public final org.apache.commons.collections.primitives.FloatIterator iterator()

Description copied from interface: FloatList

Returns an iterator over all my elements, in the appropriate sequence.

Specified by:

iterator in interface FloatList

Overrides:

iterator in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatCollection

Returns:

an iterator over all my elements.

listIterator

public org.apache.commons.collections.primitives.FloatListIterator listIterator()

Description copied from interface: FloatList

Returns a bidirectional iterator over all my elements, in the appropriate sequence.

Specified by:

listIterator in interface FloatList

Overrides:

listIterator in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

listIterator

public org.apache.commons.collections.primitives.FloatListIterator listIterator(int index)

Description copied from interface: FloatList

Returns a bidirectional 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.

Specified by:

listIterator in interface FloatList

Overrides:

listIterator in class org.apache.commons.collections.primitives.decorators.BaseProxyFloatList

get

public float get(int index)

Description copied from interface: FloatList

toArray

public float[] toArray()

Description copied from interface: FloatCollection

Returns an array containing all of my elements. The length of the returned array will be equal to my size.

The returned array will be independent of me, so that callers may modify that returned array without modifying this collection.

When I guarantee the order in which elements are returned by an iterator, the returned array will contain elements in the same order.

Specified by:

toArray in interface FloatCollection

Parameters:

a - an array that may be used to contain the elements
