A WriterOutputStream converts java.io.Writer to java.io.OutputStream.
<init>(java.io.Writer writer)Creates WriterOutputStream from given java.io.Writer object with a default encoding.

<init>(java.io.Writer writer, String encoding)Creates WriterOutputStream from given java.io.Writer object with a specified encoding.

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.
| IOException | if an I/O error occurs. | |
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.
| IOException | if an I/O error occurs. | |
write(int b)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.
| name | type | description |
|---|---|---|
| b | int | the byte. |
| IOException | if an I/O error occurs. In particular,
an IOException may be thrown if the
output stream has been closed. |
|
write(byte[] b)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).
| name | type | description |
|---|---|---|
| b | byte[] | the data. |
| IOException | if an I/O error occurs. | |
write(byte[] b, int off, int len)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 off is negative, or len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is thrown.
| name | type | description |
|---|---|---|
| b | byte[] | the data. |
| off | int | the start offset in the data. |
| len | int | the number of bytes to write. |
| IOException | if an I/O error occurs. In particular,
an IOException is thrown if the output
stream is closed. |
