I'm in a project using socket communication.

so need to send the Stream for my picture of Diagram.

but, I cant know how to save and Load.

I know there is the method , saveTo, loadFrom.
but need to have an example.

please give me the advice of saveTo(OutputStream),
and loadFrom(InputStream)

This save and loads from a memory stream:

Code
Select All
ByteArrayOutputStream out = new ByteArrayOutputStream();
try
{
	diagram.saveTo(out);
}
catch (IOException e)
{
	JOptionPane.showMessageDialog(this, e.getMessage());
	return;
}

ByteArrayInputStream in = new ByteArrayInputStream(out.toByteArray());
try
{
	diagram.loadFrom(in);
	out.close();
	in.close();
}
catch (IOException e)
{
	JOptionPane.showMessageDialog(this, e.getMessage());
	return;
}


I don't know if these methods will work with network streams. If they don't, you can use the saveToString and loadFromString methods instead, and send the string across the network.

I hope that helps,
Stoyan
