Method Detail

close back to summary

close	back to summary
public void close() throws IOException Overrides java.io.OutputStream.close. Implements java.io.Closeable.close. Doc from java.io.OutputStream.close. 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. Exceptions IOException: if an I/O error occurs.

public void close() throws IOException

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.OutputStream.close.

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.

Exceptions

IOException:: if an I/O error occurs.

finish	back to summary
public void finish() throws IOException Finish writing out the current packet without closing the underlying stream.

flush	back to summary
public void flush() throws IOException Overrides java.io.OutputStream.flush. Implements java.io.Flushable.flush. Flush the underlying stream. Exceptions IOException: Doc from java.io.OutputStream.flush. if an I/O error occurs.

flush

back to summary

public void flush() throws IOException

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Flush the underlying stream.

Exceptions

IOException:

Doc from java.io.OutputStream.flush.

if an I/O error occurs.

partialFlush	back to summary
private void partialFlush(boolean isLast) throws IOException

write back to summary

write	back to summary
public void write(int b) throws IOException Implements abstract java.io.OutputStream.write. Doc from java.io.OutputStream.write. 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. Parameters b:int the `byte`. Exceptions IOException: if an I/O error occurs. In particular, an `IOException` may be thrown if the output stream has been closed.

public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

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.

Parameters

b:int: the byte.

Exceptions

IOException:: if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

write back to summary

write	back to summary
public void write(byte[] bytes, int off, int len) throws IOException Overrides java.io.OutputStream.write. Doc from java.io.OutputStream.write. 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. 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. Parameters bytes:byte[] the data. off:int the start offset in the data. len:int the number of bytes to write. Exceptions IOException: if an I/O error occurs. In particular, an `IOException` is thrown if the output stream is closed.

public void write(byte[] bytes, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

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.

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.

Parameters

bytes:byte[]: the data.
off:int: the start offset in the data.
len:int: the number of bytes to write.

Exceptions

IOException:: if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
