Method Details

getHexDumpSlice

public static String getHexDumpSlice(IoBuffer buf,
 int offset,
 int length)

Dumps an IoBuffer to a hex formatted string.

Parameters:

buf - the buffer to dump

offset - the starting position to begin reading the hex dump

length - the number of bytes to dump

Returns:

a hex formatted string representation of the in IoBuffer.

getPrettyHexDumpSlice

public static final String getPrettyHexDumpSlice(IoBuffer buf,
 int offset,
 int length)

Produces a verbose hex dump

Parameters:

offset - initial position which to read bytes

length - number of bytes to display

Returns:

The formatted String representing the content between (offset) and (offset+count)

toPrettyHexDump

public static final String toPrettyHexDump(byte[] data,
 int pos,
 int len)

Generates a hex dump with line numbers, hex, volumes, and ascii representation

Parameters:

data - source data to read for the hex dump

pos - index position to begin reading

len - number of bytes to read

Returns:

string hex dump

toPrettyHexDumpLine

private static final String toPrettyHexDumpLine(byte[] data,
 int pos,
 int len,
 int col,
 int line)

Generates the hex dump line with hex values, columns, and ascii representation

Parameters:

data - source data to read for the hex dump

pos - index position to begin reading

len - number of bytes to read; this can be less than the line width

col - number of bytes in a column

line - line width in bytes which pads the output if len is less than line

Returns:

string hex dump

toHex

public static final String toHex(byte b)
