java.lang.Objectgoodsjpi.Persistent
goodslib.AnyArray
goodslib.ArrayOfInt
ArrayOfInt
is just that, an array of ints. It is fully
persistent, as it it's derived from Persistent. All reads cause a fetch of the
data, all writes mark it dirty and to be saved.

public ArrayOfInt(int size)
ArrayOfInt
instance.
size
- is the initial size, (length)public ArrayOfInt(int size, int allocatedSize)
ArrayOfInt
instance. (Full of false)
size
- , or length of the arrayallocatedSize
- is the size it can grow to without re-sizingpublic ArrayOfInt(int[] src)
ArrayOfInt
instance, as a copy of the given
int[]
src
- a int[]
that will be copiedMethod Detail |
public void putAt(int index, int value)
index
- an int
value, where the value should be setvalue
- the int
value to be setpublic int getAt(int index)
index
- of the int you want
int
value, at index "index"public void changeSize(int newSize)
newSize
- an int
denoting the new size.public void insert(int index, int count, int value)
insert
a "count" amount of values at a given index. Throws an
IndexOutOfBoundsException for too small (<0) or too big (>length) count or index.
index
- , where to start inserting value(s)count
- , how many values to insertvalue
- a int
value to insertpublic void remove(int index, int count)
remove
a number of values. The array shrinks in it's length, but no
resizing is done. Get an IndexOutOfBoundsException for inappropriate index or
count values.

method.
value
- , a int
to push to the stackpublic int pop()
pop
a value. (Value is removed)
IndexOutOfBoundsExceptions comes when array has hit 0 length.

top
method. This returns what
pop
returns, just it doesn't remove the value. In other stack
implementations it may be called peek()
int

append
add the given values to the end of the array
tail
- a int[]
that will be appendedpublic int[] toArray()
toArray
converts the internal representation to a int[] , of
correct size. Ie: the .length of the return == this.size()

Get a IndexOutOfBounds if the src or count don't fit
dstIndex
- , the index (of this array) where to copy tosrc
- a int[]
, where to copy fromsrcIndex
- an int
, where to start copying fromcount

, how many values to copypublic int indexOf(int val)
indexOf
returns the first occurrence of val
val
- a int
to be looked for
int
, where the value was found, or -1public int lastIndexOf(int val)
lastIndexOf
a given value
val
- a int
value to be found (from the back)
