MapConstIterator

MapConstIterator is a class for performing immutable iteration over a map. The iteration order is not specified.

1. Template Parameters

MapConstIterator has the following template parameters:

2. Public Types

MapConstIterator defines the following public types:

3. Constructors and Destructors

MapConstIterator provides the following constructors and destructors:

1. One constructor for each map implementation. The map implementations use these constructors to provide iterators.

2. A copy constructor.

3. A destructor.

4. Public Member Functions

MapConstIterator provides the following member functions.

4.1. operator=

Defined as = default.

4.2. operator==

bool operator==(const MapConstIterator& it)

Compare two MapConstIterator instances for equality.

1. If the implementations differ, then return false.

2. Otherwise check whether the implementations have equal values.

4.3. operator !=

bool operator!=(const MapConstIterator& it)

Return the negation of operator=.

4.4. operator++

MapConstIterator& operator++()
MapConstIterator& operator++(int)

Increment the iterator.

4.5. isInRange()

bool isInRange() const

Check whether the iterator is in range. It is a runtime error to attempt to access a map entry through an iterator for which isInRange evaluates to false. In this case an assertion failure will occur.

4.6. operator*

const EntryBase& operator*() const

Return a const reference to the EntryBase object pointed to by the iterator. If the iterator is not in range for the map, an assertion failure will occur. It is not recommended to use this operation after updating the map that the iterator points to.

4.7. operator->

const EntryBase* operator->() const

Return a pointer to the const EntryBase object pointed to by the iterator. If the iterator is not in range for the map, an assertion failure will occur. It is not recommended to use this operation after updating the map that the iterator points to.
