Constructor Detail

HexDumpOutputStream

public HexDumpOutputStream(java.io.Writer writer)
                    throws java.lang.NullPointerException
Create a new HexDumpWriter with the given core writer. This constructor will use a default block pattern with 8, 8, 0, 8, 8 bytes width.

Parameters:
out - The underlying writer object (must not be null).
Throws:
java.lang.NullPointerException - If the passed stream is null.

HexDumpOutputStream

public HexDumpOutputStream(java.io.Writer writer,
                           int[] blockSizes)
                    throws java.lang.NullPointerException,
                           java.lang.IllegalArgumentException
Create a new HexDumpWriter with the given core writer. The passed blockSizes-array should contain a set of int elements - each >= 0 - where each specify the byte-size for each block to be printed. Zero-elements (0) are allowed to create spacer columns but the sum of all must not be null.

Parameters:
out - The underlying writer object (must not be null).
blockSizes - The desired output block size (in bytes, not in chars).
Throws:
java.lang.NullPointerException - If the passed writer or blockSizes array is null.
java.lang.IllegalArgumentException - If the blockSizes array is empty or has no non-zero element sum.
Method Detail

isClosed

public boolean isClosed()

Throws:
java.io.IOException

flush

public void flush()
           throws java.io.IOException
Specified by:
flush in interface java.io.Flushable
Overrides:
flush in class java.io.OutputStream
Throws:
java.io.IOException

write

public void write(int b)
           throws java.io.IOException
Specified by:
write in class java.io.OutputStream
Throws:
java.io.IOException

main
