void org.objectweb.proactive.core.filetransfer.FileBlock.loadNextBlock

(

BufferedInputStream

bis

)

throws IOException

Loads the FileBlock object with a block from the source file this block references.

If the parameter is null, then it will create a new buffer from the parameters stored in the block instance. Note that creating a new block requires performing a skip (seek) on the stream, which is very slow. Therefore it is better to pass the buffered stream as parameter.

void org.objectweb.proactive.core.filetransfer.FileBlock.saveCurrentBlock

(
