Re: [Vtd-xml-users] Random Access Proposal (take 2)

[Rodrigo C. <rn...@gm...>]

Hi Jimmy!

I've tested the new random access API... it doesn't quite work the way I 
expected, for example:

AutoPilot ap = new AutoPilot(vn);
ap.bind(vn);
ap.selectElement("ServiceID");
NodeRecorder myContext = new NodeRecorder(vn);
while(ap.iterate()){
    myContext.record();
    // do something messy
    myContext.resetPointer();
}

resetPointer also affects ap context precluding it from correctly 
cycling the values.

Why don't you just export something similar to what is kept in the stack 
anyway? A context is so simple, you just need an efficient byte array...

When you ask for context repositioning you just have to overwrite the 
values in "vn", no need for anything more. A context is (should be) the 
equivalent to a stack position, nothing more...

I think I sent you my altered ximpleware_1.6, do you want the code to 
look again?

This is a simple context:

/**
* This class is used to store a single context of VTDNav class.
*/
public class SimpleContext{
    private int[] buf;
    private int bufsize = 0;
    public SimpleContext(int[] in) {
        // This allows both allocation during creation and allocating
        // an adequate buffer size so that no further reallocation is
        // needed in the future.
        if (in != null) {
            buf = in.clone();
            bufsize = in.length;
        } else {
            buf = new int[0];
            bufsize = 0;
        }
    }
    public void set(int[] in) {
        if (buf.length < in.length) {
            buf = in.clone();
        } else {
            System.arraycopy(in,0,buf,0,in.length);
            bufsize = in.length;
        }
    }
    public boolean get(int[] out) {
        if (bufsize > 0) {
            if (out.length != buf.length) {
                out = buf.clone();
            } else {
                System.arraycopy(buf,0,out,0,bufsize);
            }
            return true;
        } else {
            return false;
        }
    }
}
