get_new_iterator: ITERATOR[E_]
frozen
effective function
{ANY}
top
This feature is obsolete: Use `new_iterator' instead. This historical SmartEiffel feature is badly named.
for_each (action: PROCEDURE[TUPLE[TUPLE 1[E_]]])
effective procedure
{ANY}
top
Apply action to every item of Current.
See also for_all, exists, aggregate.
require
  • action /= Void
for_all (test: FUNCTION[TUPLE[TUPLE 1[E_]]]): BOOLEAN
effective function
{ANY}
top
Do all items satisfy test?
See also for_each, exists, aggregate.
require
  • test /= Void
exists (test: FUNCTION[TUPLE[TUPLE 1[E_]]]): BOOLEAN
effective function
{ANY}
top
Does at least one item satisfy test?
See also for_each, for_all, aggregate.
require
  • test /= Void
aggregate (action: FUNCTION[TUPLE[TUPLE 2[E_, E_], E_]], initial: E_): E_
effective function
{ANY}
top
Aggregate all the elements starting from the initial value.
See also for_each, for_all, exists.
require
  • action /= Void
out_in_tagged_out_memory
effective procedure
{ANY}
top
Append terse printable representation of current object in tagged_out_memory.
require
  • locked: tagged_out_locked
ensure
  • still_locked: tagged_out_locked
  • not_cleared: tagged_out_memory.count >= old tagged_out_memory.count
  • append_only: old tagged_out_memory.twin.is_equal(tagged_out_memory.substring(1, old tagged_out_memory.count))

count: INTEGER_32
deferred function
{ANY}
top
Number of available items in the hoard.
See also is_empty
ensure
  • Result >= 0
is_empty: BOOLEAN
deferred function
{ANY}
top
Is the hoard empty ?
See also count.
ensure
  • definition: Result = count = 0
do_all (action: ROUTINE[TUPLE[TUPLE 1[E_]]])
frozen
effective procedure
{ANY}
top
Apply action to every item of Current.
This feature is obsolete: Use `for_each` instead. This feature is not secure because it accepts a FUNCTION, the result of which is lost.
