Public Methods

public void close ()

Closes the stream, flushing it first. Once the stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously closed stream has no effect.

Throws
IOException

public void flush ()

Flushes the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams.

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.

Throws
IOException

public void flushBuffer ()

Throws
IOException

public static StreamEncoder forEncoder (WritableByteChannel ch, CharsetEncoder enc, int minBufferCap)

public static StreamEncoder forOutputStreamWriter (OutputStream out, Object lock, CharsetEncoder enc)

public static StreamEncoder forOutputStreamWriter (OutputStream out, Object lock, String charsetName)

Throws
UnsupportedEncodingException

public static StreamEncoder forOutputStreamWriter (OutputStream out, Object lock, Charset cs)

public String getEncoding ()

public void write (char[] cbuf, int off, int len)

Writes a portion of an array of characters.

Parameters
cbuf Array of characters
off Offset from which to start writing characters
len Number of characters to write
Throws
IOException

public void write (String str, int off, int len)

Writes a portion of a string.

Parameters
str A String
off Offset from which to start writing characters
len Number of characters to write
Throws
IOException

public void write (int c)

Writes a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.

Subclasses that intend to support efficient single-character output should override this method.

Parameters
c int specifying a character to be written
Throws
IOException
