java.lang.Objectgoodsjpi.Persistent
goodslib.AnyArray
goodslib.ArrayOfShort
ArrayOfShort
is just that, an array of shorts. 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 ArrayOfShort(int size)
ArrayOfShort
instance.
size
- is the initial size, (length)public ArrayOfShort(int size, int allocatedSize)
ArrayOfShort
instance. (Full of false)
size
- , or length of the arrayallocatedSize
- is the size it can grow to without re-sizingpublic ArrayOfShort(short[] src)
ArrayOfShort
instance, as a copy of the given
short[]
src
- a short[]
that will be copiedMethod Detail |
public void putAt(int index, short value)
index
- an int
value, where the value should be setvalue
- the short
value to be setpublic short getAt(int index)
index
- of the short you want
short
value, at index "index"public void changeSize(int newSize)
newSize
- an int
denoting the new size.public void insert(int index, int count, short 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 short
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 short
to push to the stackpublic short 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()
short

append
add the given values to the end of the array
tail
- a short[]
that will be appendedpublic short[] toArray()
toArray
converts the internal representation to a short[] , 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 short[]
, where to copy fromsrcIndex
- an int
, where to start copying fromcount

indexOf
returns the first occurrence of val
val
- a short

int
, where the value was found, or -1public int lastIndexOf(short val)
lastIndexOf
a given value
val
- a short
value to be found (from the back)
