Hi,
As I mentioned in the other thread, before the problem of partial database
updates can be solved, we must first be able to determine if a Feature has
been modified. This is not currently possible in all of the JUMP variants
that I am familiar with, although Kosmo may have implemented it.
The simplest way of implementing it that I can see is to modify BasicFeature
to include:
private int[] attributeModCount; //this is a parallel array to Object[]
attributes
Then it would be necessary to allocate the attributeModCount array when
setAttributes(Object[] attributes) is called.
In addition each time setAttribute(int attributeIndex, Object newAttribute)
is called, add the line of code:
attributeModCount[attributeIndex]++
With these modifications we could then define:
public boolean isFeatureModified() {
for (int i=0; i<attributeModCount.length; i++) {
if (attributeModCount[i] > 1) //modified is defined as setting an
attribute more than once
return true;
}
return false;
}
Would this work and does this seem like something we should consider?
regards,
Larry
