- Public Member Functions inherited from ezArrayMapBase< KEY, VALUE >
 ezArrayMapBase (ezAllocator *pAllocator)
 Constructor.
 
 ezArrayMapBase (const ezArrayMapBase &rhs, ezAllocator *pAllocator)
 Copy-Constructor.
 
void operator= (const ezArrayMapBase &rhs)
 Copy assignment operator.
 
ezUInt32 GetCount () const
 Returns the number of elements stored in the map.
 
bool IsEmpty () const
 True if the map contains no elements.
 
void Clear ()
 Purges all elements from the map.
 
template<typename CompatibleKeyType , typename CompatibleValueType >
ezUInt32 Insert (CompatibleKeyType &&key, CompatibleValueType &&value)
 Always inserts a new value under the given key. Duplicates are allowed. Returns the index of the newly added element.
 
void Sort () const
 Ensures the internal data structure is sorted. This is done automatically every time a lookup needs to be made.
 
template<typename CompatibleKeyType >
ezUInt32 Find (const CompatibleKeyType &key) const
 Returns an index to one element with the given key. If the key is inserted multiple times, there is no guarantee which one is returned. Returns ezInvalidIndex when no such element exists.
 
template<typename CompatibleKeyType >
ezUInt32 LowerBound (const CompatibleKeyType &key) const
 Returns the index to the first element with a key equal or larger than the given key. Returns ezInvalidIndex when no such element exists. If there are multiple keys with the same value, the one at the smallest index is returned.
 
template<typename CompatibleKeyType >
ezUInt32 UpperBound (const CompatibleKeyType &key) const
 Returns the index to the first element with a key that is LARGER than the given key. Returns ezInvalidIndex when no such element exists. If there are multiple keys with the same value, the one at the smallest index is returned.
 
const KEY & GetKey (ezUInt32 uiIndex) const
 Returns the key that is stored at the given index.
 
const VALUE & GetValue (ezUInt32 uiIndex) const
 Returns the value that is stored at the given index.
 
VALUE & GetValue (ezUInt32 uiIndex)
 Returns the value that is stored at the given index.
 
ezDynamicArray< Pair > & GetData ()
 Returns a reference to the map data array.
 
const ezDynamicArray< Pair > & GetData () const
 Returns a constant reference to the map data array.
 
template<typename CompatibleKeyType >
VALUE & FindOrAdd (const CompatibleKeyType &key, bool *out_pExisted=nullptr)
 Returns the value stored at the given key. If none exists, one is created. bExisted indicates whether an element needed to be created.
 
template<typename CompatibleKeyType >
VALUE & operator[] (const CompatibleKeyType &key)
 Same as FindOrAdd.
 
const PairGetPair (ezUInt32 uiIndex) const
 Returns the key/value pair at the given index.
 
void RemoveAtAndCopy (ezUInt32 uiIndex, bool bKeepSorted=false)
 Removes the element at the given index. More...
 
template<typename CompatibleKeyType >
bool RemoveAndCopy (const CompatibleKeyType &key, bool bKeepSorted=false)
 Removes one element with the given key. Returns true, if one was found and removed. If the same key exists multiple times, you need to call this function multiple times to remove them all. More...
 
template<typename CompatibleKeyType >
bool Contains (const CompatibleKeyType &key) const
 Returns whether an element with the given key exists.
 
template<typename CompatibleKeyType >
bool Contains (const CompatibleKeyType &key, const VALUE &value) const
 Returns whether an element with the given key and value already exists.
 
void Reserve (ezUInt32 uiSize)
 Reserves enough memory to store size elements.
 
void Compact ()
 Compacts the internal memory to not waste any space.
 
bool operator== (const ezArrayMapBase< KEY, VALUE > &rhs) const
 Compares the two containers for equality.
 
 EZ_ADD_DEFAULT_OPERATOR_NOTEQUAL (const ezArrayMapBase< KEY, VALUE > &)
 
ezUInt64 GetHeapMemoryUsage () const
 Returns the amount of bytes that are currently allocated on the heap.
 
template<typename CompatibleKeyType >
EZ_ALWAYS_INLINE VALUE & operator[] (const CompatibleKeyType &key)
 
template<typename CompatibleKeyType >
EZ_ALWAYS_INLINE bool Contains (const CompatibleKeyType &key) const
