## Detailed Description

template<typename KeyType, typename ValueType, class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>
struct juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator

Iterates over the items in a HashMap.

To use it, repeatedly call next() until it returns false, e.g.

HashMap <String, String> myMap;
HashMap<String, String>::Iterator i (myMap);
while (i.next())
{
DBG (i.getKey() << " -> " << i.getValue());
}
juce::HashMap::HashMap
HashMap(int numberOfSlots=defaultHashTableSize, HashFunctionType hashFunction=HashFunctionType())
Definition juce_HashMap.h:121
juce::HashMap::Iterator
Definition juce_HashMap.h:400

The order in which items are iterated bears no resemblance to the order in which they were originally added!

Obviously as soon as you call any non-const methods on the original hash-map, any iterators that were created beforehand will cease to be valid, and should not be used.

## Constructor & Destructor Documentation

## ◆ Iterator() [1/2]

template<typename KeyType , typename ValueType , class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>

juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator::Iterator | ( | const HashMap & | hashMapToIterate | ) |
| inline noexcept

Definition at line 401 of file juce_HashMap.h.

## ◆ Iterator() [2/2]

template<typename KeyType , typename ValueType , class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>

juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator::Iterator | ( | const Iterator & | other | ) |

## Member Function Documentation

## ◆ getKey()

template<typename KeyType , typename ValueType , class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>

KeyType juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator::getKey | ( |  | ) | const
| inline

Returns the current item's key. This should only be called when a call to next() has just returned true.

Definition at line 432 of file juce_HashMap.h.

## ◆ getValue()

template<typename KeyType , typename ValueType , class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>

ValueType juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator::getValue | ( |  | ) | const
| inline

Returns the current item's value. This should only be called when a call to next() has just returned true.

Definition at line 440 of file juce_HashMap.h.

## ◆ next()

template<typename KeyType , typename ValueType , class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>

bool juce::HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator::next | ( |  | ) |
| inline noexcept

Moves to the next item, if one is available. When this returns true, you can get the item's key and value using getKey() and getValue(). If it returns false, the iteration has finished and you should stop.
