Constructor Detail

Dumper

public Dumper(int addressOffset)

Construct a new Dumper.

Parameters:

addressOffset - int; address for the first byte that will be appended

Dumper

public Dumper()

Construct a new Dumper with addressOffset 0.

Method Detail

setOutputStream

public Dumper<T> setOutputStream(OutputStream newOutputStream)

Set or replace the active output stream. (The default output stream is System.out.)

Parameters:

newOutputStream - OutputStream; the new output stream

Returns:

Dumper<T>; this Dumper object (for method chaining)

setSuppressMultipleIdenticalLines

public Dumper<T> setSuppressMultipleIdenticalLines(boolean newState)

Set the output compression mode.

Parameters:

newState - boolean; if true; groups of three or more output lines with the significant content are compressed; if false; no output is suppressed

Returns:

Dumper<T>; this Dumper object (for method chaining)

addDecoder

public void addDecoder(Decoder decoder)

Add a Decoder at the end of the current list of decoders.

Parameters:

decoder - Decoder; the decoder to add or insert

addDecoder

public Dumper<T> addDecoder(int index,
                            Decoder decoder)
                     throws IndexOutOfBoundsException

Add a Decoder at a specified index.

Parameters:

index - int; the position where the Decoder must be added (inserted)

decoder - Decoder; the decoder to add or insert

Returns:

Dumper<T>; this Dumper object (for method chaining)

Throws:

IndexOutOfBoundsException - when the provided index is invalid

append

public boolean append(byte theByte)
               throws IOException

Append one byte to this dump.

Parameters:

theByte - byte; the byte to append

Returns:

boolean; true if output was generated; false if the byte was accumulated, but did not result in immediate output

Throws:

IOException - when output was generated and writing to the output stream generated an IOException

append

public Dumper<T> append(byte[] bytes)
                 throws IOException

Append an array of bytes.

Parameters:

bytes - byte[]; the bytes to append

Returns:

Dumper<T>; this Dumper object (for method chaining)

Throws:

IOException - when an outputStream has been set and it throws an IOException

append

public Dumper<T> append(byte[] bytes,
                        int start,
                        int len)
                 throws IOException

Append a slice of an array of bytes.

Parameters:

bytes - byte[]; byte array from which to take the bytes to append

start - int; index of first byte in bytes to append (NB. using non-zero does not cause a jump in the address that is printed before the dumped bytes)

len - int; number of bytes to append

Returns:

Dumper<T>; this Dumper object (for method chaining)

Throws:

IOException - when an outputStream has been set and it throws an IOException

append

public Dumper<T> append(InputStream inputStream)
                 throws IOException

Consume an entire input stream and append what it produces to this Dumpmer. The input stream is not closed by this append method. This method does not return until the inputStream returns end of file, or throws an IOException (which is - actually - not a return to the caller, but a jump to the closest handler for that exception).

Parameters:

inputStream - InputStream; the input stream that is to be consumed

Returns:

Dumper<T>; this Dumper object (for method chaining)

Throws:

IOException - when the inputStream throws that exception, or when an output stream has been set and that throws an IOException

flush

public boolean flush()
              throws IOException

Force the currently assembled output to be written (write partial result if the output line currently being assembled is not full).

Returns:

boolean; true if output was generated; false if no output was generated

Throws:

IOException - when output was generated and writing to the output stream generated an IOException

getMaximumWidth

public int getMaximumWidth()

Return the maximum width of an output line.

Returns:

int; the maximum width of an output line

toString

public String toString()

Overrides:

toString in class Object
