  - containsKey
```
@Deprecated
boolean containsKey(Object key)
```
    Deprecated. Use specialization containsKey(int) instead
    
    Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)
    
    Specified by:
    
    containsKey in interface Map<Integer,Float>
    
    Parameters:
    key - key whose presence in this map is to be tested
    
    Returns:
    true if this map contains a mapping for the specified key
  - containsKey
```
boolean containsKey(int key)
```
    Returns true if this map contains a mapping for the specified key.
    
    Parameters:
    key - the int key whose presence in this map is to be tested
    
    Returns:
    true if this map contains a mapping for the specified key
  - containsValue
```
@Deprecated
boolean containsValue(Object value)
```
    Deprecated. Use specialization containsValue(float) instead
    
    Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.
    
    Specified by:
    
    containsValue in interface Map<Integer,Float>
    
    Parameters:
    value - value whose presence in this map is to be tested
    
    Returns:
    true if this map maps one or more keys to the specified value
  - containsValue
```
boolean containsValue(float value)
```
    Returns true if this map maps one or more keys to the specified value. This operation will probably require time linear in the map size for most implementations of the IntFloatMap interface.
    
    Parameters:
    value - the float value whose presence in this map is to be tested
    
    Returns:
    true if this map maps one or more keys to the specified value
  - get
```
@Nullable
@Deprecated
Float get(Object key)
```
    Deprecated. Use specialization get(int) instead
    
    Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.
    More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)
    If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.
    
    Specified by:
    
    get in interface Map<Integer,Float>
    
    Parameters:
    key - the key whose associated value is to be returned

  - get
```
float get(int key)
```

  - forEach
```
void forEach(@Nonnull
           IntFloatConsumer action)
```
    Performs the given action on each entry in this map until all entries have been processed or the action throws an Exception. Exceptions thrown by the action are relayed to the caller.

    Comparison of iteration options in the library
  - forEachWhile
```
boolean forEachWhile(@Nonnull
                   IntFloatPredicate predicate)
```
    Checks the given predicate on each entry in this map until all entries have been processed or the predicate returns false for some entry, or throws an Exception. Exceptions thrown by the predicate are relayed to the caller.
    The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.
    If the map is empty, this method returns true immediately.
    
    Parameters:
    predicate - the predicate to be checked for each entry
    
    Returns:
    true if the predicate returned true for all entries of the map, false if it returned false for the entry

  - keySet
```
@Nonnull
IntSet keySet()
```
    Description copied from interface: java.util.Map
    
    Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    keySet in interface Map<Integer,Float>
    
    Returns:

  - values
```
@Nonnull
FloatCollection values()
```
    Description copied from interface: java.util.Map
    
    Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    values in interface Map<Integer,Float>
    
    Returns:

  - entrySet
```
@Nonnull
ObjSet<Map.Entry<Integer,Float>> entrySet()
```
    Description copied from interface: java.util.Map
    
    Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    entrySet in interface Map<Integer,Float>

    the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)
  - put
```
float put(int key,
        float value)
```
    Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value.

    Parameters:
    key - key with which the specified value is to be associated
    value - value to be associated with the specified key
    
    Returns:
    the previous value associated with key, or default value if there was no mapping for key. (A default value return can also indicate that the map previously associated default value with key.)

    value - value to be associated with the specified key
    
    Returns:
    the previous value associated with the specified key, or default value if there was no mapping for the key. (A default value return can also indicate that the map previously associated default value with the key, if the implementation supports such values.)

                    @Nonnull
                    IntToFloatFunction mappingFunction)
```
    If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map . The most common usage is to construct a new object serving as an initial mapped value or memoized result.
    If the function itself throws an (unchecked) exception, the exception is rethrown, and no mapping is recorded.
    
    Parameters:
    key - key with which the specified value is to be associated
    mappingFunction - the function to compute a value
    
    Returns:
    the current (existing or computed) value associated with the specified key

```
    If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.
    If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.
    
    Parameters:
    key - key with which the specified value is to be associated
    remappingFunction - the function to compute a value
    
    Returns:
    the new value associated with the specified key, or "no entry" value
    
    Throws:
    
    UnsupportedOperationException - if the put operation is not supported by this map
  - merge
```
float merge(int key,
          float value,
          @Nonnull
          FloatBinaryOperator remappingFunction)
```
    If the specified key is not already associated with a value, associates it with the given value, otherwise, replaces the value with the results of the given remapping function. This method may be of use when combining multiple mapped values for a key.
    If the remappingFunction itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.
    
    Parameters:
    key - key with which the specified value is to be associated
    value - the value to use if absent
    remappingFunction - the function to recompute a value if present
    
    Returns:

    Parameters:
    key - the key to which value add the given value
    addition - the value to add
    
    Returns:
    the new value associated with the specified key

             float defaultValue)
```
    Adds the given addition value to the value associated with the specified key, or defaultValue if this map contains no mapping for the key, and associates the resulting value with the key.
    This version of addValue(int, float) is useful if you want to count values from the different initial value, than the default value of this map.
    
    Parameters:
    key - the key to which value add the given value
    addition - the value to add
    defaultValue - the value to be used if the map contains no mapping for the given key

```
@Nullable
@Deprecated
Float remove(Object key)
```
    Deprecated. Use specialization remove(int) instead
    
    Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The map can contain at most one such mapping.)
    Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.
    If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.
    The map will not contain a mapping for the specified key once the call returns.
    
    Specified by:
    
    remove in interface Map<Integer,Float>
    
    Parameters:
    key - key whose mapping is to be removed from the map
    
    Returns:
    the previous value associated with key, or null if there was no mapping for key.
  - remove
```
float remove(int key)
```
    Removes the mapping for a key from this map if it is present (optional operation).
    Returns the value to which this map previously associated the key, or default value if the map contained no mapping for the key.
    A return value of default value does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to default value.
    The map will not contain a mapping for the specified key once the call returns.
    
    Parameters:
    key - key whose mapping is to be removed from the map
    
    Returns:
    the previous value associated with key, or default value if there was no mapping for key
    
    Throws:
    
    UnsupportedOperationException - if the remove operation is not supported by this map
  - remove
```
@Deprecated
boolean remove(Object key,
                        Object value)
```
    Deprecated. Use specialization remove(int, float) instead
    
    Removes the entry for the specified key only if it is currently mapped to the specified value.
    
    Parameters:
    key - key with which the specified value is associated
    value - value expected to be associated with the specified key
    
    Returns:
    true if the value was removed
    
    Throws:
    
    NullPointerException - if the specified key or value is null
    
    UnsupportedOperationException - if the remove operation is not supported by this map
  - remove
```
boolean remove(int key,
             float value)
```
    Removes the entry for the specified key only if it is currently mapped to the specified value.
    
    Parameters:
    key - key with which the specified value is associated
    value - value expected to be associated with the specified key
    
    Returns:
    true if the value was removed
    
    Throws:
    
    UnsupportedOperationException - if the remove operation is not supported by this map
  - removeIf
```
boolean removeIf(@Nonnull
               IntFloatPredicate filter)
```
    Removes all of the entries of this collection that satisfy the given predicate. Errors or runtime exceptions thrown during iteration or by the predicate are relayed to the caller.
    
    Parameters:
    filter - a predicate which returns true for elements to be removed
    
    Returns:
    true if any elements were removed
    
    Throws:
    
    NullPointerException - if the specified filter is null
    
    UnsupportedOperationException - if elements cannot be removed from this collection. Implementations may throw this exception if a matching element cannot be removed or if, in general, removal is not supported.
