CONCEPT
remote - what is it, where is it?
DESCRIPTION
The new object library, residing in /std, makes extensive use of the
concept of a remote object.
The remote object is an object that holds utilities for another
object. This means that it has functions the other object can call;
functions that will, in some way, provide services for the calling
object.
Why is this done, you might ask. The answer is that there are several
reasons. A few examples might shed some light on it.
1/ The remote object holds a set of functions that will be used by a
group of objects. Collecting those in a single object, rather than
having all of them in all objects, saves memory.
2/ The remote object holds a large data base, and a group of objects
needs that. By keeping this data base in a remote object, and
asking that for the data saves memory.
So, what object can be used as a remote object? The answer is: any
object! For example, an object can use itself as the remote object.
This is rather common in the case of monsters that won't appear in
hordes.
EXAMPLES
See
/examples/armour/ring.c
/examples/state_harry.c
for examples.
NOTE
To see exactly what objects in the /std lib uses remote functions and
exactly which ones, check out the documentation on those objects.
