Hello fred,
Thanks for the reply, so just for clarifiation, if I am using a
property which will be "indexed" then the getters and setters will be a
little different from the usual set and get
Ie
public String getBidAmount(int index) {
return bidAmount[index];
}
And
public void setBidAmount(int index, String val) {
bidAmount[index] = val;
}
And have to implement the bidAmoutn as an array?
Protected String[] bidAmount;
Do confirm if igot that right?
Thanks once again for ur time.

Rajat,
Here is an example of an indexed property called 'signal' (in my
application it holds complex objects, not simple strings or integers):
public OrderedSignalBean getSignal(int index) {
while( index >= this.getSignals().size() ){
this.getSignals().add(new OrderedSignalBean());
}
return (OrderedSignalBean) this.getSignals().get(index);
}
public void setSignal(int index, OrderedSignalBean signal) {
while ( index >= signals.size() ){
signals.add(new OrderedSignalBean());
}
signals.set(index, signal);
}
The 'signals' member is private and is of type 'ArrayList'. It is
created in the form's contructor and the reset method of the form :
signals = new ArrayList().
The setter and getter methods of the indexed property perform so-clled
"lazy-initialization" so you do not have to worry about the siez of the
array list.
Hope this helps.
Fred
