Class WriterOutputStream

public WriterOutputStream(Writer writer)

public void close()
            throws IOException

This method closes the stream. Any internal or native resources associated with this stream are freed. Any subsequent attempt to access the stream might throw an exception.

This method in this class does nothing.

Specified by:

close in interface Closeable

close in interface AutoCloseable

Overrides:

close in interface OutputStream

Throws:

IOException - If an error occurs

public void flush()
            throws IOException

This method forces any data that may have been buffered to be written to the underlying output device. Please note that the host environment might perform its own buffering unbeknowst to Java. In that case, a write made (for example, to a disk drive) might be cached in OS buffers instead of actually being written to disk.

This method in this class does nothing.

Specified by:

flush in interface Flushable

Overrides:

flush in interface OutputStream

Throws:

IOException - If an error occurs

public void write(byte[] b)
            throws IOException

This method all the writes bytes from the passed array to the output stream. This method is equivalent to write(b, 0, buf.length) which is exactly how it is implemented in this class.

Overrides:

write in interface OutputStream

Parameters:

b - The array of bytes to write

Throws:

IOException - If an error occurs

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

This method writes len bytes from the specified array b starting at index off into the array.

This method in this class calls the single byte write() method in a loop until all bytes have been written. Subclasses should override this method if possible in order to provide a more efficent implementation.

Overrides:

write in interface OutputStream

Parameters:

b - The array of bytes to write from

off - The index into the array to start writing from

len - The number of bytes to write

Throws:

IOException - If an error occurs

public void write(int c)
            throws IOException

This method writes a single byte to the output stream. The byte written is the low eight bits of the int passed and a argument.

Subclasses must provide an implementation of this abstract method

Overrides:

write in interface OutputStream

Parameters:

Throws:

IOException - If an error occurs
