TpIntsetFastIter

typedef struct {
} TpIntsetFastIter;

An opaque structure representing iteration in undefined order over a set of integers. Must be initialized with tp_intset_fast_iter_init().

Before 0.11.16, this type was called TpIntSetFastIter, which is now a backwards compatibility typedef.

Usage is similar to GHashTableIter:

1
2
3
4
5
6
7
8
9

TpIntsetFastIter iter;
guint element;

tp_intset_fast_iter_init (&iter, intset);

while (tp_intset_fast_iter_next (&iter, &element))
{
  printf ("%u is in the intset\n", element);
}

Since 0.11.6

tp_intset_fast_iter_init ()

void                tp_intset_fast_iter_init            (TpIntsetFastIter *iter,
                                                         const TpIntset *set);

Initialize iter to iterate over set in arbitrary order. iter will become invalid if set is modified.

Since 0.11.6

tp_intset_fast_iter_next ()

gboolean            tp_intset_fast_iter_next            (TpIntsetFastIter *iter,
                                                         guint *output);

Advances iter and retrieves the integer it now points to. Iteration is not necessarily in numerical order.

Since 0.11.6

TP_INTSET_ITER_INIT()

#define TP_INTSET_ITER_INIT(set) { (set), (guint)(-1) }

A suitable static initializer for a TpIntsetIter, to be used as follows:

1
2
3
4
5
6

void
do_something (const TpIntset *intset)
{
  TpIntsetIter iter = TP_INTSET_ITER_INIT (intset);
  /* ... do something with iter ... */
}

Since 0.11.6, consider using TpIntsetFastIter if iteration in numerical order is not required.

TpIntsetIter

typedef struct {
    const TpIntset *set;
    guint element;
} TpIntsetIter;

A structure representing iteration over a set of integers. Must be initialized with either TP_INTSET_ITER_INIT() or tp_intset_iter_init().

Since 0.11.6, consider using TpIntsetFastIter if iteration in numerical order is not required.

Before 0.11.16, this type was called TpIntSetIter, which is now a backwards compatibility typedef.

tp_intset_iter_init()

#define tp_intset_iter_init(iter, set) tp_intset_iter_init_inline (iter, set)

Reset the iterator iter to the beginning and make it iterate over set.

tp_intset_iter_next ()

gboolean            tp_intset_iter_next                 (TpIntsetIter *iter);

If there are integers in (iter->set) higher than (iter->element), set (iter->element) to the next one and return TRUE. Otherwise return FALSE.

Usage:

1
2
3
4
5

TpIntsetIter iter = TP_INTSET_INIT (intset);
while (tp_intset_iter_next (&iter))
{
  printf ("%u is in the intset\n", iter.element);
}

Since 0.11.6, consider using TpIntsetFastIter if iteration in numerical order is not required.

tp_intset_iter_reset()

#define tp_intset_iter_reset(iter) tp_intset_iter_reset_inline (iter)

Reset the iterator iter to the beginning. It must already be associated with a set.
