Hi All
I have been trying to use the DataOutputBuffer class for its obvious memory
efficiency. I basically write some data into the buffer and then write the
buffer into a file (an instance of RandomAccessFile) by invoking
buffer.getData(). However what I am seeing is that a lot of garbage is being
written into the file which manifests itself as a series of '@' characters
in Linux and spaces on Windows.
This is my usage :
DataOutputBuffer buffer = new DataOutputBuffer();
RandomAccessFile raf = new RandomAccessFile(file, "rw");
for ( each data in some data structure )
{
buffer.reset();
serialize data into buffer;
raf.write(buffer.getData());
}
When I use ByteArrayOutputStream and a DataOutputStream to do the same task
the size of the generated file is 29K. However when I use the
DataOutputBuffer the size of the file for the same dataset it 507K. Is my
usage correct ?
Please advice
THanks
A
