public Class WriterOutputStream

extends OutputStream
Class Inheritance
Imports
java.io.IOException, .OutputStream, .Writer, java.nio.ByteBuffer, .CharBuffer, java.nio.charset.Charset, .CharsetDecoder, .CoderResult, .CodingErrorAction
Redirects an OutputStream to a Writer by decoding the data using the specified Charset.

Note

This class should only be used if it is necessary to redirect an OutputStream to a Writer for compatibility purposes. It is much more efficient to write to the Writer directly.

Method Summary

Modifier and TypeMethod and Description
public void
close()

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Closes this output stream and releases any system resources associated with this stream.
public void
flush()

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Flushes this output stream and forces any buffered output bytes to be written out.
private void
flushOutput()

Flush the output.

private void
processInput(final boolean
indicates end of input
endOfInput)

Decode the contents of the input ByteBuffer into a CharBuffer.

public void
write(int
the byte.
b)

Implements abstract java.io.OutputStream.write.

Writes the specified byte to this output stream.
public void
write(byte[]
the data.
b)

Overrides java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream.
public void
write(byte[]
the data.
b, int
the start offset in the data.
off, int
the number of bytes to write.
len)

Overrides java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream.
Inherited from java.io.OutputStream:

Method Detail

closeback to summary
public void close() throws IOException

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.OutputStream.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

Exceptions
IOException:
if an I/O error occurs.
flushback to summary
public void flush() throws IOException

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Doc from java.io.OutputStream.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.

flushOutputback to summary
private void flushOutput() throws IOException

Flush the output.

Exceptions
IOException:
if an I/O error occurs
processInputback to summary
private void processInput(final boolean endOfInput) throws IOException

Decode the contents of the input ByteBuffer into a CharBuffer.

Parameters
endOfInput:boolean

indicates end of input

Exceptions
IOException:
if an I/O error occurs
writeback to summary
public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from 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.
writeback to summary
public void write(byte[] b) throws IOException

Overrides java.io.OutputStream.write.

Doc from 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.
writeback to summary
public void write(byte[] b, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from 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 b is null, a NullPointerException is thrown.

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.
