Constructor Detail

BlobOutputStream

public BlobOutputStream(LargeObject lo)

Create an OutputStream to a large object.

Parameters:

lo - LargeObject

BlobOutputStream

public BlobOutputStream(LargeObject lo,
                int bsize)

Create an OutputStream to a large object.

lo - LargeObject

bsize - The size of the buffer used to improve performance

Method Detail

write

public void write(int b)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

write

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

Overrides:

write in class OutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

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.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - if an I/O error occurs.

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException
