Constructor Summary

HexDumpOutputStream(java.io.OutputStream out, int width)
Creates an output stream filter built on top of the specified underlying output stream.

Method Summary

void	flush() Flushes this output stream and forces any buffered output bytes to be written out to the stream.
static java.lang.String	toHexString(byte[] buf, int length) Returns a hex representation of the buffer.

Constructor Detail

HexDumpOutputStream

public HexDumpOutputStream(java.io.OutputStream out,
                           int width)

Creates an output stream filter built on top of the specified underlying output stream.

Parameters:

out - the underlying output stream to be assigned to the field this.out for later use, or null if this instance is to be created without an underlying stream.

width - The number of bytes to print in a line of output.

Method Detail

toHexString

public static java.lang.String toHexString(byte[] buf,
                                           int length)

Returns a hex representation of the buffer.

Parameters:

buf - The buffer.

length - The length

Returns:

String - a hex representation of the buffer.

write

public void write(int b)
           throws java.io.IOException

Writes the specified byte to this output stream.

The write method of FilterOutputStream calls the write method of its underlying output stream, that is, it performs out.write(b).

Implements the abstract write method of OutputStream.

Overrides:

write in class HexEncodingOutputStream

Parameters:

b - the byte.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out to the stream.

The flush method of FilterOutputStream calls the flush method of its underlying output stream.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException - if an I/O error occurs.
