Method details

write

public void write(int arg0) throws IOException
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.

Throws

IOException

write

public void write(byte[] arg0, int arg1, int arg2) throws IOException
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.

Throws

IOException

deflate

protected void deflate() throws IOException

Throws

IOException

finish

public void finish() throws IOException

Throws

IOException

flush

public void flush() throws IOException
Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination. The flush method of OutputStream does nothing.

Throws

IOException

close

public void close() throws IOException
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.

Throws

IOException
