Class LOBOutputStream

java.lang.Object
java.io.OutputStream
org.apache.derby.impl.jdbc.LOBOutputStream
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable

public class LOBOutputStream extends OutputStream
This is an output stream built on top of LOBStreamControl. All the write methods are routed to LOBStreamControl.

    • write

      public void write(int b) throws 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 argument b. The 24 high-order bits of b are ignored.

      Subclasses of OutputStream must provide an implementation for this method.

      Specified by:
      write in class OutputStream
      Parameters:
      b - the byte.
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
    • write

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

      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.

      Overrides:
      write in class OutputStream
      Parameters:
      b - the data.
      off - the start offset in the data.
      len - the number of bytes to write.
      Throws:
      IOException - if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
    • close

      public void close() throws IOException
      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.

      The close method of OutputStream does nothing.

      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class OutputStream
      Throws:
      IOException - if an I/O error occurs.
