java.lang.Objectjava.io.OutputStream
org.apache.derby.impl.jdbc.ClobAsciiStream
final class ClobAsciiStream
Wrap a Writer as an OutputStream to support Clob.setAsciiStream(). Any value written to the OutputStream is a valid ASCII value (0-255 from JDBC 4 spec appendix C2) thus this class simply passes the written values onto the Writer.

public void write(int b) throws java.io.IOException
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.
write
in class java.io.OutputStream
b
- the byte
.
java.io.IOException
- if an I/O error occurs. In particular,
an IOException
may be thrown if the
output stream has been closed.public void write(byte[] b, int off, int len) throws java.io.IOException
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.
The write
method of OutputStream
calls
the write method of one argument on each of the bytes to be
written out. Subclasses are encouraged to override this method and
provide a more efficient implementation.
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.
write
in class java.io.OutputStream
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.
java.io.IOException
- if an I/O error occurs. In particular,
an IOException
is thrown if the output
stream is closed.
