Re: Listing objects

Following on from Lüpher Cypher's message. . . 
Hi,

Suppose we have a hierarchical class structure that looks something like
this:

Sorry, I lost the plot half way through.

Your objects can be
1 - nesting : object has a 'what are my children' and 'who is my parent' functionality.

2 - pointing : eg object has a 'these are my siblings' or 'previous/next' functionality

3 - dictionary entries : object in some container is discoverable by name

Variations and combinations of course apply. BUT every object exists in some context. I /think/ you might be trying to get A's to point-to/own B's where more than one A could be the parent of a B. Eg
"Sally is daughter of Jean"
"Geoffrey is son of Teddy"
"Sally is daughter of Teddy" // Only one Sally! J+T are married.

In this case[1] create an array of children and point to elements in that array from your parent objects.

eg $child['Sally'] = new ChildObj(.....);
then $Jean->AddChild('Sally') // just a key name or index
or $Jean->AddChild($child['Sally']) // inside the routine do $myKids[] = & $NewChild
where $NewChild is the function argument.

[1] If in this example children can be parents then you should be looking at a single universal 'person' class with the necessary links.
