Class ClobAsciiStream
- java.lang.Object

- java.io.OutputStream

- org.apache.derby.impl.jdbc.ClobAsciiStream
-
- All Implemented Interfaces:
java.io.Closeable
,java.io.Flushable
,java.lang.AutoCloseable
final class ClobAsciiStream extends java.io.OutputStream
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.

Method Detail
-
write
public void write(int b) throws java.io.IOException
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 argumentb
. The 24 high-order bits ofb
are ignored.- Specified by:
write
in classjava.io.OutputStream
- Parameters:
b
- thebyte
.- Throws:
java.io.IOException
- if an I/O error occurs. In particular, anIOException
may be thrown if the output stream has been closed.

write
public void write(byte[] b, int off, int len) throws java.io.IOException
Writeslen
bytes from the specified byte array starting at offsetoff
to this output stream.The general contract for
write(b, off, len)
is that some of the bytes in the arrayb
are written to the output stream in order; elementb[off]
is the first byte written andb[off+len-1]
is the last byte written by this operation.The
write
method ofOutputStream
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
isnull
, aNullPointerException
is thrown.If
off
is negative, orlen
is negative, oroff+len
is greater than the length of the arrayb
, then an IndexOutOfBoundsException is thrown.- Overrides:
write
in classjava.io.OutputStream
- Parameters:
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.- Throws:
java.io.IOException
- if an I/O error occurs. In particular, anIOException
is thrown if the output stream is closed.
