public class FloatList extends java.lang.Object implements java.lang.Cloneable, java.io.Serializable, FloatConsumer, VoidToFloatGenerator
FloatList represents a list of float values.
It provides list- and stack-oriented methods for insertion, addition,
and removal, of values. The methods are not thread-safe.| Modifier and Type | Field and Description |
|---|---|
float[] |
elements
The array holding the elements.
|
int |
size

FloatList()
Constructs a new
FloatList. |
FloatList(float[] elements)
Constructs a new

This generator method yields all values to
cons. |
float |
get(int index)
Returns the list element at
index. |
int |
hashCode() |
int |
indexOf(float o)
Returns the index of
o in this list. |
boolean |
isEmpty()
Returns if this list is empty, i.e., if its size is zero.
|
int |
lastIndexOf(float o)
Returns the last index of
o in this list. |
float |
peek(int index)
Returns the list element at
index as seen from
the top, i.e., at absolute position size - index. |
float |
pop()
Removes and returns the object at the top of this list.
|
FloatList |
push(float o)
Pushes
o on top of this list, i.e., as last element. |
FloatList |
push(float o1,
float o2)
Pushes
o1 and o2 on top of this list,
i.e., as last elements. |
FloatList |
push(float o1,
float o2,
float o3)
Pushes
o1 ... o3 on top of this list,
i.e., as last elements. |
boolean |
remove(float o)
Removes the element
o. |
float |
removeAt(int index)

index. |
float |
set(int index,
float o)
Sets the element at position
index to o. |
