## com.sun.javatest.util
Class WriterStream

    java.lang.Object
      java.io.OutputStream
          com.sun.javatest.util.WriterStream

All Implemented Interfaces:
  java.io.Closeable, java.io.Flushable

    public class WriterStream

extends java.io.OutputStream

Note: this class should be JDK 1.1 compatible

Constructor Summary
`WriterStream(java.io.Writer w)` Create a stream that writes to a writer.
`WriterStream(java.io.Writer w, java.lang.String charsetName)` Create a stream that writes to a writer.

Method Summary
`void` | `close()` We override default implementation to write last characters, which could be lost in buffer otherwise.
`void` | `flush()` Flush the stream.
`void` | `write(int b)` OutputStream's implementation.

Methods inherited from class java.io.OutputStream
`write, write`

Methods inherited from class java.lang.Object
`clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`

Constructor Detail

### WriterStream

    public WriterStream(java.io.Writer w)

  Create a stream that writes to a writer.

  Parameters:
    `w` - the writer

### WriterStream

    public WriterStream(java.io.Writer w,
                        java.lang.String charsetName)

  Create a stream that writes to a writer.

  Parameters:
    `w` - the writer
    `charsetName` - name of encoding to be used when decode byte stream (instead of default one)

Method Detail

### flush

    public void flush()
               throws java.io.IOException

  Flush the stream.

  Specified by:
    `flush` in interface `java.io.Flushable`
  Overrides:
    `flush` in class `java.io.OutputStream`
  Throws:
    `java.io.IOException` - if an I/O error occurs

### close

    public void close()
               throws java.io.IOException

  We override default implementation to write last characters, which could be lost in buffer otherwise.

  Specified by:
    `close` in interface `java.io.Closeable`
  Overrides:
    `close` in class `java.io.OutputStream`
  Throws:
    `java.io.IOException`

### write

    public void write(int b)
               throws java.io.IOException

  OutputStream's implementation. Our goal is to convert encoded byte stream form OutputStream to char stream, which can be written using specified writer. We perform this by collecting bytes in buffer and checking with PERIOD_SIZE interval if this buffer represents some char sequence. If so, we write to writer all chars, except last one. We don't write last char, because there still not enough bytes could be collected for it.

  Specified by:
    `write` in class `java.io.OutputStream`
  Parameters:
    `b` - next byte from OutputStream to write.
  Throws:
    `java.io.IOException`
