Java OutputStreamWriter
OutputStreamWriter is a class which is used to convert character stream to byte stream, the characters are encoded into byte using a specified charset. write() method calls the encoding converter which converts the character into bytes. The resulting bytes are then accumulated in a buffer before being written into the underlying output stream. The characters passed to write() methods are not buffered. We optimize the performance of OutputStreamWriter by using it with in a BufferedWriter so that to avoid frequent converter invocation.
Constructor
| Constructor | Description |
|---|---|
| OutputStreamWriter(OutputStream out) | It creates an OutputStreamWriter that uses the default character encoding. |
| OutputStreamWriter(OutputStream out, Charset cs) | It creates an OutputStreamWriter that uses the given charset. |
| OutputStreamWriter(OutputStream out, CharsetEncoder enc) | It creates an OutputStreamWriter that uses the given charset encoder. |
| OutputStreamWriter(OutputStream out, String charsetName) | It creates an OutputStreamWriter that uses the named charset. |
Methods
| Modifier and Type | Method | Description |
|---|---|---|
| void | close() | It closes the stream, flushing it first. |
| void | flush() | It flushes the stream. |
| String | getEncoding() | It returns the name of the character encoding being used by this stream. |
| void | write(char[] cbuf, int off, int len) | It writes a portion of an array of characters. |
| void | write(int c) | It writes a single character. |
| void | write(String str, int off, int len) | It writes a portion of a string. |
