CGAL::CC_safe_handle< CC_iterator > Class Template Reference
STL Extensions for CGAL Reference | Compact Container

`#include <CGAL/CC_safe_handle.h>`

## Definition

The class `CC_safe_handle` is a helper class that stores an iterator on a `Compact_container` (or `Concurrent_compact_container`) and is able to know if the pointee has been erased after the creation of the `CC_safe_handle` instance.

It stores the iterator and the erase counter value of the pointee when the `CC_safe_handle` instance was created. It can only be used when the pointee type is a model of the `ObjectWithEraseCounter` concept.

Template Parameters

  CC_iterator | is the type of the stored iterator (on a `Compact_container` or a `Concurrent_compact_container`)

  `Concurrent_compact_container`

## Creation

| CC_safe_handle (CC_iterator iterator)
| Introduces a safe handle from a `Compact_container` iterator.

## Access Member Functions

bool | is_zombie () const
| Returns `true` if the pointee has been erased, i.e. if the iterator points to a freed object or to another object.
CC_iterator | cc_iterator () const
| Returns the stored `Compact_container` iterator.
