2.14. Delegation
Squirrel supports implicit delegation. Every table or userdata can have a parent table (delegate). A parent table is a normal table that allows the definition of special behaviors for his child. When a table (or userdata) is indexed with a key that doesn’t correspond to one of its slots, the interpreter automatically delegates the get (or set) operation to its parent.:
Entity <- {
}
function Entity::DoStuff()
{
::print(_name);
}
local newentity = {
_name="I'm the new entity"
}
newentity.setdelegate(Entity)
newentity.DoStuff(); //prints "I'm the new entity"
The delegate of a table can be retreived through built-in method table.getdelegate()
.:
local thedelegate = newentity.getdelegate();
