(weak-set-member?object weak-set) procedure
boolean
``Populations'' have been renamed to ``weak-sets''. This change was made in the belief that ``weak-set'' is a more intuitive name then ``population''. The old names are still supported, but they will be removed in a future release.
| make-population | $&rarr#longrightarrow;$ | make-weak-set |
| population? | $&rarr#longrightarrow;$ | weak-set? |
| add-to-population | $&rarr#longrightarrow;$ | add-to-weak-set! |
| remove-from-population | $&rarr#longrightarrow;$ | remove-from-weak-set! |
| population->list | $&rarr#longrightarrow;$ | weak-set->list |
| walk-population | $&rarr#longrightarrow;$ | walk-weak-set |
In addition, two new procedures on weak-sets have been added.
(weak-set-member?object weak-set) procedure
boolean
weak-set-member? returns true if object is a member of weak-set; otherwise, it returns false.
(weak-set-empty?weak-set) procedure
boolean
weak-set-empty? returns true if weak-set is empty; otherwise, it returns false.
