To load all entities in this example compile and load the loader file:
|
|
|
|
| ?- logtalk_load(loader).
|
|
|
|
You will need to load the objects in the roots and relations examples.
|
|
|
|
You will also need to load the following files in the library directory:
|
|
events_loader, types_loader, metapredicates_loader, and hierarchies_loader.
|
|
Alternatively, you may load the library all_loader file to load all library
|
|
entities.
|
|
|
|
This folder contains an example of representation and handling of
|
|
relations using events. We have instances of class brick and a binary
|
|
brick_stack relation between the bricks. Every time we move a brick, we
|
|
want the bricks on top of it to move along. If we break the stack by
|
|
moving a middle brick, we want to automatically destroy the
|
|
corresponding relation tuple.
|
|
|
|
It's instructive to use the event debugger in the Logtalk library (loader
|
|
file debugging_loader.lgt) to better understand this example. Set spy points
|
|
in all brick instances and then activate the debugger.
