public class Memory

extends java.lang.Object

Class Memory has static utility methods for allocating, clearing, and dumping an Object-valued memory array.

Constructor Summary

Memory()

Method Summary

static java.lang.Object[]	allocate(int size) Allocate an Object-valued memory array of the given size.
static void	clear(java.lang.Object[] mem) Set all elements of the given memory to null.
static void	dump(java.lang.Object[] mem, int numElems) Dump the given number of elements in the given memory to stdout.
static void	dump(java.lang.Object[] mem, int startElem, int endElem) Dump the given memory to stdout, from the given startElem to endElem indices, inclusive.
static void	dump(java.lang.Object[] mem, int startElem, int endElem, int indent) Same as dump(Object[], int, int), but with indent of locations.
static void	dumpRelative(java.lang.Object[] mem, int startElem, int endElem) Dump the given memory to stdout, from the given startElem to endElem indices, inclusive.
static void	dumpRelative(java.lang.Object[] mem, int startElem, int endElem, int indent) Same as dumpRelative, but with indent of locations.

public Memory()

Method Detail

allocate

public static java.lang.Object[] allocate(int size)

Allocate an Object-valued memory array of the given size.

clear

public static void clear(java.lang.Object[] mem)

Set all elements of the given memory to null.

dump

public static void dump(java.lang.Object[] mem,
                        int numElems)

Dump the given number of elements in the given memory to stdout. The dump starts at memory location 0. The dump of each element is started on a separate line, prefixed with "Location n: ", for n = the index of that location. The number of lines dumped per element is dependent on the toString method for the type of element being dumped.

dump

public static void dump(java.lang.Object[] mem,
                        int startElem,
                        int endElem)

Dump the given memory to stdout, from the given startElem to endElem indices, inclusive. Note that in the "Location n: " dump prefixes, the value of n is an absolute address relative to overall location 0. Cf. dumpRelative.

dumpRelative

public static void dumpRelative(java.lang.Object[] mem,
                                int startElem,
                                int endElem)

Dump the given memory to stdout, from the given startElem to endElem indices, inclusive. The difference between this method and the other three-argument version of dump is that here the "Location n: " prefixes start at 0, so this dump is relative to the given startElem beginning at 0 instead of its absolute value.

dump

public static void dump(java.lang.Object[] mem,
                        int startElem,
                        int endElem,
                        int indent)

Same as dump(Object[], int, int), but with indent of locations.

dumpRelative

public static void dumpRelative(java.lang.Object[] mem,
                                int startElem,
                                int endElem,
                                int indent)

Same as dumpRelative, but with indent of locations.
