Method Detail

getTokens

protected List<byte[]> getTokens(byte[] buf,
                                 int off,
                                 int len)
                          throws IOException

Splits the current buffer into tokens; the criteria for splitting consists in considering each new line as a token and everything else as another token. If we have e.g.: "AAAA\nBBBB", we would have 3 tokens: "AAAA","\n","BBBB"; Note that a buffer not containing any new line is considered a single token e.g. buffer "AAAA" is considered as the single token "AAAA"

Parameters:

buf - the data.

off - the start offset in the data.

len - the number of bytes to write.

Returns:

the list of tokens in the data; joining the tokens you get the original data.

Throws:

IOException - in case something goes wrong while managing streams internally

write

public void write(int b)

Overrides:

write in class PrintStream

write

public void write(byte[] buf,
                  int off,
                  int len)

Prints the data with properly colored background and foreground; takes care of adding a line header to each line

Overrides:

write in class PrintStream

Parameters:

buf - the data.

off - the start offset in the data.

len - the number of bytes to write.
