# ACE\_Bounded\_Set\_Iterator(3)

Interates through an unordered set.

## NAME

ACE\_Bounded\_Set\_Iterator -  Interates through an unordered set.

## SYNOPSIS

```
#include <ace/Containers.h>
template<class T>
class ACE_Bounded_Set_Iterator
{
  public:
    ACE_Bounded_Set_Iterator (ACE_Bounded_Set<T> &s);
    int next (T *&next_item);
    int advance (void);
    int first (void);
    int done (void) const;
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
  private:
    ACE_Bounded_Set<T> &s_;
    ssize_t next_;
};
```

## DESCRIPTION

This implementation of an unordered set uses a fixed array. This implementation does not allow duplicates...

## Initialization method.

```
ACE_Bounded_Set_Iterator (ACE_Bounded_Set<T> &s);
```

## Iteration methods.

```
int next (T *&next_item);
```

Pass back the next\_item that hasn't been seen in the Set. Returns 0 when all items have been seen, else 1.

```
int advance (void);
```

Move forward by one element in the set.  Returns 0 when all the items in the set have been seen, else 1.

```
int first (void);
```

Move to the first element in the set.  Returns 0 if the set is empty, else 1.

```
int done (void) const;
```

Returns 1 when all items have been seen, else 0.

```
void dump (void) const;
```

Dump the state of an object.

```
ACE_ALLOC_HOOK_DECLARE;
```

Declare the dynamic allocation hooks.
