Summary
Class invariant
Overview
creation features
  • make
    Creates an empty dictionary.
exported features
Counting:
Basic access:
  • has (k: K_): BOOLEAN
    Is there a value currently associated with key k?
  • infix "@" (k: K_): V_
    The infix notation which is actually a synonym for at.
  • fast_has (k: K_): BOOLEAN
    Is there a value currently associated with key k?
Removing:
  • remove (k: K_)
    Remove entry k (which may exist or not before this call).
  • fast_remove (k: K_)
    Same job as remove, but uses basic = for comparison.
To provide iterating facilities:

Other features:
capacity: INTEGER_32
effective function
Approximation of the actual internal storage capacity.
at (k: K_): V_
effective function
Return the value associated to key k.
fast_at (k: K_): V_
effective function
Return the value associated to key k using basic = for comparison.
reference_at (k: K_): V_
effective function
Return Void or the value associated with key k.
fast_reference_at (k: K_): V_
effective function
Same work as reference_at, but basic = is used for comparison.
put (v: V_, k: K_)
effective procedure
Change some existing entry or add the new one.
add (v: V_, k: K_)
effective procedure
To add a new entry k with its associated value v.
fast_put (v: V_, k: K_)
effective procedure
Same job as put, but uses basic = for comparison.
occurrences (v: V_): INTEGER_32
effective function
Number of occurrences using is_equal for comparison.
fast_occurrences (v: V_): INTEGER_32
effective function
Number of occurrences using basic = for comparison.
key_at (v: V_): K_
effective function
Retrieve the key used for value v using is_equal for comparison.
fast_key_at (v: V_): K_
effective function
Retrieve the key used for value v using = for comparison.
clear_count
effective procedure
Discard all items (is_empty is True after that call).
clear_count_and_capacity
effective procedure
Discard all items (is_empty is True after that call).
item (index: INTEGER_32): V_
effective function
Item at the corresponding index i.
key (index: INTEGER_32): K_
effective function
get_new_iterator_on_keys: ITERATOR[K_]
effective function
internal_key (k: K_): K_
effective function
Retrieve the internal key object which correspond to the existing entry k (the one memorized into the Current dictionary).
copy (other: AVL_DICTIONARY [V_, K_ -> COMPARABLE])
effective procedure
Reinitialize by copying all associations of other.
is_empty: BOOLEAN
effective function
Is it empty?
has (k: K_): BOOLEAN
deferred function
Is there a value currently associated with key k?
infix "@" (k: K_): V_
frozen
effective function
The infix notation which is actually a synonym for at.
fast_has (k: K_): BOOLEAN
deferred function
Is there a value currently associated with key k?
remove (k: K_)
deferred procedure
Remove entry k (which may exist or not before this call).
fast_remove (k: K_)
deferred procedure
Same job as remove, but uses basic = for comparison.
lower: INTEGER_32
constant attribute
Minimum index.
upper: INTEGER_32
effective function
Maximum index.
first: V_
effective function
The very first item.
last: V_
effective function
The last item.
get_new_iterator_on_items: ITERATOR[V_]
effective function
key_map_in (buffer: COLLECTION[K_])
effective procedure
Append in buffer, all available keys (this may be useful to speed up the traversal).
