Details

A ScopeList is a helper object used to build the list of objects in scope. This object provides methods for the common ways of adding objects to scope.

The ScopeList isn't a true Collection object, but it mimics one by providing most of the standard methods. You can use length() and the [] operator to scan the list, perform a foreach or for..in loop with a ScopeList to iterate over the items in scope, you can use find() to check if a given object is in scope, and you can use subset() to get a list of in-scope objects satisfying some condition.

Properties  

status_query.t[1180]

A LookupTable with the objects already added to the list. We use this to avoid redundantly scanning containment trees for objects that we've already added. For each object, we set status_[obj] to a status indicator:


nil (unset) - the object has never been visited
1 - we've added the object only, not its contents
2 - we've added the object and its contents

vec_query.t[1168]
a vector with the objects in scope

Methods  

add (obj)query.t[1056]

Add an object and its contents to the scope.

addAll (lst)query.t[1086]
Add all of the objects in the given list

addOnly (obj)query.t[1114]
Add a single object to the scope. This doesn't add anything related to the object (such as its contents) - just the object itself.

addSelfIlluminatingWithin (obj)query.t[1104]
add each self-illuminating object in the interior contents

addWithin (obj)query.t[1096]
Add the interior contents of an object to the scope. This adds only the contents, not the object itself.

close ( )query.t[1134]
"close" the scope list - this converts the vector to a list

createIterator ( )query.t[1162]
create an iterator, for foreach()

createLiveIterator ( )query.t[1165]
create a live iterator

find (obj)query.t[1147]
is the given object in scope?

length ( )query.t[1141]
get the number of items in scope

subset (func)query.t[1156]
get the subset of the objects in scope matching the given condition

toList ( )query.t[1159]
return the scope as a simple list of objects
