Package lava.array Description

Array manipulation and conversion

Details: This package contains functions for manipulating arrays, grouped into classes by similarity.

Most of the array conversion functions in this package take on the form

desttype[] funcname (srctype[] src, int from, desttype[] dest, int to, int amount)

where

funcname

is the name of the static method

srctype

is the primitive type of the source array (byte, short, int, float, etc.)

src

is the source array

from

is the starting index in the source array

desttype

is the primitive type of the destination array (byte, short, int, float, etc.)

dest

is the destination array

to

is the starting index in the destination array

amt

is the number of elements from the source array to process

the return value

is dest, returned for convenience

If src is null, no action is taken and null is returned. If dest is null, a new array of the correct destination type is created whose length is just long enough to accomodate the requested operation, and that new array is returned.

This package also contains ByteArray32, a class that efficiently simulates a sparsely populated 32-bit-addressable memory space. ByteArray32 has turned out to be useful in several computer science research applications and in other situations where large byte caches are required.
