oracle.ifs.utils.io.Dump

public class Dump
extends Object

The Dump class provides a mechanism to "dump" bytes to a PrintStream in a human-readable format. The bytes are displayed in hexadecimal, 16 bytes to a line, followed by an ASCII (actually 1-byte unicode) representation.

Method Detail

main

public static void main(String[] args)

Tests the Dump class. If no arguments are given, this method dumps 256 random bytes. Otherwise, the first argument is interpreted as a file to dump.

dumpData

public static void dumpData(byte[] buf,
                            int offset,
                            int len,
                            PrintStream out)

Outputs a byte array to a PrintStream.

Parameters:

buf - array to dump

offset - the offset in the stream (for display purposes, not offset into the byte array)

len - the number of bytes to display

dumpData

public static void dumpData(byte[] buf,
                            int offset,
                            int len,
                            PrintWriter out)

Outputs a byte array to a PrintWriter.

Parameters:

buf - array to dump

offset - the offset in the stream (for display purposes, not offset into the byte array)

len - the number of bytes to display

dumpData

public static void dumpData(byte[] buf,
                            PrintStream out)

Outputs a byte array to a PrintStream.

Parameters:

buf - the byte array to dump.

dumpData

public static void dumpData(byte[] buf,
                            PrintWriter out)

Outputs a byte array to a PrintWriter.

Parameters:

buf - the byte array to dump.

toString

public static String toString(byte[] buf,
                              int off,
                              int len)

Outputs a byte array to a String.

Parameters:

buf - the byte array to dump.

off - the offset into the byte array to start from.

len - the length of data to output.

Returns:

the String dump of the byte array.

toString

public static String toString(byte[] buf)

Outputs a byte array to a String.

Parameters:

buf - the byte array to dump.

Returns:

the String dump of the byte array.

toString

public static String toString(byte[] buf,
                              String header)

Outputs a byte array to a String, including a header line.

Parameters:

buf - the byte array to dump.

header - the header that will come before the byte array dump.

Returns:

the String dump of the byte array.

toString

public static String toString(byte[] buf,
                              int off,
                              int len,
                              String header)

Outputs a byte array to a String, including a header line.

Parameters:

buf - the byte array to dump.

off - the offset into the byte array to start from.

len - the length of data to output.

header - the header that will come before the byte array dump.

Returns:

the String dump of the byte array.
