private void byte2char(ByteBuffer bytes, CharBuffer chars) throws IOException

close back to summary

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

public void close() throws IOException

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.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.

Annotations

@Override

Exceptions

IOException:: if an I/O error occurs.

flush back to summary

flush	back to summary
public void flush() throws IOException Overrides java.io.OutputStream.flush. Implements java.io.Flushable.flush. 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. If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive. Annotations @Override Exceptions IOException: if an I/O error occurs.

public void flush() throws IOException

Implements java.io.Flushable.flush.

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.

If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

write back to summary

write	back to summary
public void write(int b) throws IOException Implements abstract 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`. Annotations @Override 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.

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.

Annotations

@Override

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[] b) throws IOException Overrides java.io.OutputStream.write. Writes `b.length` bytes from the specified byte array to this output stream. The general contract for `write(b)` is that it should have exactly the same effect as the call `write(b, 0, b.length)`. Parameters b:byte[] the data. Annotations @Override Exceptions IOException: if an I/O error occurs. See Also `java.io.OutputStream#write(byte[], int, int)`

public void write(byte[] b) throws IOException

Overrides java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).

Parameters

b:byte[]: the data.

Annotations

@Override

Exceptions

IOException:: if an I/O error occurs.

write back to summary

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

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

Overrides 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 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

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

Annotations

@Override

Exceptions

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