public class Debug

extends java.lang.Object

This class encapsulates a small collection of hopefully useful debug utilities. All methods are static to keep performance up and memory usage down. We don't want these things to get in the way of the application we're trying to debug.

Method Summary

static boolean	arrayComp(byte[] str1, int offset1, byte[] str2, int offset2, int length) Quick function to compare two byte arrays.
static boolean	arrayComp(char[] str1, int offset1, char[] str2, int offset2, int length) Deprecated.
static void	arrayCopyByteChar(byte[] str1, int offset1, char[] str2, int offset2, int length)
static void	arrayCopyCharByte(char[] str1, int offset1, byte[] str2, int offset2, int length)
static void	debugDump(byte[] arr, int length) Dump an array to info port.
static void	debugDump(int b) Dump a byte to info port.
static void	debugDump(java.lang.String out) Dump a string to info port.
static void	hexDump(byte[] b) Dump hex representation of a byte array to System.out.
static void	hexDump(byte[] b, int length) Dump hex representation of a byte array to System.out.
static void	hexDump(int i) Dump hex representation of a four byte int to System.out.
static void	intDump(int iVal) Dump hex representation of a four byte int to System.out.

                                int length)

Quick function to compare two byte arrays.

Parameters:

str1 - first array

offset1 - first array starting offset

str2 - second array

offset2 - second array starting offset

length - number of bytes to compare

Returns:

true if arrays compare favorably.

arrayComp

public static boolean arrayComp(char[] str1,
                                int offset1,
                                char[] str2,

                                int length)

Deprecated.

Quick function to compare a character array to a byte array. This only looks at the LSB of the character vs. the byte in the other array.

Parameters:

str1 - first array

offset1 - first array starting offset

str2 - second array

offset2 - second array starting offset

length - number of bytes to compare

Returns:

true if arrays compare favorably.

setDefaultStreams

public static void setDefaultStreams()

Sets the old TINI default streams to Serial port 0. Binds System.out, System.err, and System.in.
