Method Detail

write

public void write(int)
Description copied from class: OutputStream
Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Subclasses of OutputStream must provide an implementation for this method.

Specified by:
write in class OutputStream
Parameters:
- the byte.

write

public void write(byte[],
                  int,
                  int)
Description copied from class: OutputStream
Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Overrides:
write in class OutputStream
Parameters:
- the data.
- the start offset in the data.
- the number of bytes to write.

writeTo

public void writeTo(OutputStream)
             throws IOException
IOException

reset

public void reset()

toByteArray

public byte[] toByteArray()

size

public int size()

toString

public String toString()
Description copied from class: Object
Returns the empty string. It's here to satisfy javac.

Overrides:
toString in class Object

toString

public String toString(String)
                throws UnsupportedEncodingException
UnsupportedEncodingException

toString

public String toString(int)

close

public void close()
           throws IOException
Description copied from class: OutputStream
Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

The close method of OutputStream does nothing.

Overrides:
close in class OutputStream
Throws:
IOException - if an I/O error occurs.
