- Method Detail
  - getNoEntryKey
```
float getNoEntryKey()
```
    Returns the value that represents null in the keySet(). The default value is generally zero, but can be configured during construction of the collection.
    
    Returns:
    
    the value that represents a null value in this collection.
  - size
```
int size()
```
    Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
    
    Returns:
    
    the number of key-value mappings in this map
  - isEmpty
```
boolean isEmpty()
```
    Returns true if this map contains no key-value mappings.
    
    Returns:
    
    true if this map contains no key-value mappings
  - containsKey
```
boolean containsKey(float key)
```
    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.equals(k). (There can be at most one such mapping.)
    
    Parameters:
    
    key - key whose presence in this map is to be tested
    
    Returns:
    
    true if this map contains a mapping for the specified key
    
    Throws:
    
    java.lang.ClassCastException - if the key is of an inappropriate type for this map (optional)
    
    java.lang.NullPointerException - if the specified key is null and this map does not permit null keys (optional)
  - containsValue
```
boolean containsValue(java.lang.Object value)
```
    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.
    
    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
    
    Throws:
    
    java.lang.ClassCastException - if the value is of an inappropriate type for this map (optional)
    
    java.lang.NullPointerException - if the specified value is null and this map does not permit null values (optional)
  - get
```
V get(float key)
```
    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.
    
    Parameters:
    
    key - the key whose associated value is to be returned
    
    Returns:
    
    the float value to which the specified key is mapped, or null if this map contains no mapping for the key
    
    Throws:
    
    java.lang.ClassCastException - if the key is of an inappropriate type for this map (optional)
    
    java.lang.NullPointerException - if the specified key is null and this map does not permit null keys (optional)
  - put
```
V put(float key,
      V 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. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)
    
    Parameters:
    
    key - key with which the specified value is to be associated
    
    value - an float value value to be associated with the specified key
    
    Returns:
    
    the previous value associated with key, or no_entry_value if there was no mapping for key. (A no_entry_value return can also indicate that the map previously associated null with key, if the implementation supports null values.)
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the put operation is not supported by this map
    
    java.lang.ClassCastException - if the class of the specified key or value prevents it from being stored in this map
    
    java.lang.NullPointerException - if the specified key or value is null and this map does not permit null keys or values
    
    java.lang.IllegalArgumentException - if some property of the specified key or value prevents it from being stored in this map
    
    See Also:
    
    getNoEntryKey()
  - putIfAbsent
```
V putIfAbsent(float key,
              V value)
```
    Inserts a key/value pair into the map if the specified key is not already associated with a value.
    
    Parameters:
    
    key - key with which the specified value is to be associated
    
    value - an float value to be associated with the specified key
    
    Returns:
    
    the previous value associated with key, or null if none was found.
  - remove
```
V remove(float key)
```
    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.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.
    
    Parameters:
    
    key - key whose mapping is to be removed from the map
    
    Returns:
    
    the previous float value associated with key, or null if there was no mapping for key.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the remove operation is not supported by this map
    
    java.lang.ClassCastException - if the key is of an inappropriate type for this map (optional)
    
    java.lang.NullPointerException - if the specified key is null and this map does not permit null keys (optional)
  - putAll
```
void putAll(java.util.Map<? extends java.lang.Float,? extends V> m)
```
    Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
    
    Parameters:
    
    m - mappings to be stored in this map
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the putAll operation is not supported by this map
    
    java.lang.ClassCastException - if the class of a key or value in the specified map prevents it from being stored in this map
    
    java.lang.NullPointerException - if the specified map is null, or if this map does not permit null keys or values, and the specified map contains null keys or values
    
    java.lang.IllegalArgumentException - if some property of a key or value in the specified map prevents it from being stored in this map
  - putAll
```
void putAll(TFloatObjectMap<? extends V> map)
```
    Put all the entries from the given map into this map.
    
    Parameters:
    
    map - The map from which entries will be obtained to put into this map.
  - clear
```
void clear()
```
    Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the clear operation is not supported by this map
  - keySet
```
TFloatSet keySet()
```
    Returns a TFloatSet 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.
    
    Returns:
    
    a set view of the keys contained in this map
  - keys
```
float[] keys()
```
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Returns:
    
    a copy of the keys of the map as an array.
  - keys
```
float[] keys(float[] array)
```
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
    
    Returns:
    
    the keys of the map as an array.
  - valueCollection
```
java.util.Collection<V> valueCollection()
```
    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.
    
    Returns:
    
    a collection view of the values contained in this map
  - values
```
java.lang.Object[] values()
```
    Returns the values of the map as an Object array. Note that the array returned is typed as an Object[] and may not be cast to a more specific type. See values(Object[]) for a version which allows specifically typed arrays. Changes to the array of values will not be reflected in the map nor vice-versa.
    
    Returns:
    
    the values of the map as an array of float values.
  - values
```
V[] values(V[] array)
```
    Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
    
    Returns:
    
    the values of the map as an array of float values.
  - iterator
```
TFloatObjectIterator<V> iterator()
```
    Returns a TFloatObjectIterator with access to this map's keys and values.
    
    Returns:
    
    a TFloatObjectIterator with access to this map's keys and values.
  - forEachKey
```
boolean forEachKey(TFloatProcedure procedure)
```
    Executes procedure for each key in the map.
    
    Parameters:
    
    procedure - a TObjectProcedure value
    
    Returns:
    
    false if the loop over the keys terminated because the procedure returned false for some key.
  - forEachValue
```
boolean forEachValue(TObjectProcedure<? super V> procedure)
```
    Executes procedure for each value in the map.
    
    Parameters:
    
    procedure - a TObjectProcedure value
    
    Returns:
    
    false if the loop over the values terminated because the procedure returned false for some value.
  - forEachEntry
```
boolean forEachEntry(TFloatObjectProcedure<? super V> procedure)
```
    Executes procedure for each key/value entry in the map.
    
    Parameters:
    
    procedure - a TFloatObjectProcedure value
    
    Returns:
    
    false if the loop over the entries terminated because the procedure returned false for some entry.
  - transformValues
```
void transformValues(TObjectFunction<V,V> function)
```
    Transform the values in this map using function.
    
    Parameters:
    
    function - a TObjectFunction value
  - retainEntries
```
boolean retainEntries(TFloatObjectProcedure<? super V> procedure)
```
    Retains only those entries in the map for which the procedure returns a true value.
    
    Parameters:
    
    procedure - determines which entries to keep
    
    Returns:
    
    true if the map was modified.
  - equals
```
boolean equals(java.lang.Object o)
```
    Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    o - object to be compared for equality with this map
    
    Returns:
    
    true if the specified object is equal to this map
  - hashCode
```
int hashCode()
```
    Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object.hashCode().
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the hash code value for this map
