The adapter is implemented as a wrapper around a primitive map. Thus, changes to the underlying map are reflected by this map and vice versa. See Also:   FloatKeyMap See Also:   java.util.Map author:    Søren Bak version:    1.1 20-08-2003 23:03 since:    1.0 Inner Class :class EntrySet extends AbstractSet Inner Class :class Entry implements Map.Entry Field Summary protected  FloatKeyMap map      The underlying primitive map. Constructor Summary public   FloatKeyMapToMapAdapter(FloatKeyMap map)      Creates a new adaption of a primitive map of float keys to a Java Collections Framework map. Method Summary public  void clear()      Clears this map. public  boolean containsKey(Object key)      Indicates whether this map contains a mapping from a specified key. public  boolean containsValue(Object value)      Indicates whether this map contains a mapping to a specified value. public  Set entrySet()      Returns a set view of the entries of this map. public  boolean equals(Object obj)      Indicates whether this map is equal to some object. Parameters:   obj - the object with which to compare this map. public  Object get(Object key)      Maps a specified key to a value. public  int hashCode()      Returns a hash code value for this map. public  boolean isEmpty()      Indicates whether this map is empty. public  Set keySet()      Returns a set view of the keys of this map. public  Object put(Object key, Object value)      Adds a mapping from a specified key to a specified value to this map. public  void putAll(Map map)      Adds all mappings from a specified map to this map. public  Object remove(Object key)      Removes the mapping from a specified key from this map. The mapping is removed from the underlying map. Parameters:   key - the key whose mapping to remove from this map. public  int size()      Returns the size of this map. public  Collection values()      Returns a collection view of the values in this map. Field Detail map protected FloatKeyMap map(Code) The underlying primitive map. Constructor Detail FloatKeyMapToMapAdapter public FloatKeyMapToMapAdapter(FloatKeyMap map)(Code) Creates a new adaption of a primitive map of float keys to a Java Collections Framework map. Parameters:   map - the underlying primitive map. throws:   NullPointerException - if map is null. Method Detail clear public void clear()(Code) Clears this map. The underlying map is cleared. throws:   UnsupportedOperationException - if the operation is not supported by theunderlying map. containsKey public boolean containsKey(Object key)(Code) Indicates whether this map contains a mapping from a specified key. This is so, only if the underlying collection contains the unwrapped key. Parameters:   key - the key to test for. true if this map contains a mapping fromthe specified key; returns falseotherwise. throws:   NullPointerException - if key is null. throws:   ClassCastException - if key is not of class Float Float. containsValue public boolean containsValue(Object value)(Code) Indicates whether this map contains a mapping to a specified value. Parameters:   value - the value to test for. true if this map contains at least onemapping to the specified value; returnsfalse otherwise. entrySet public Set entrySet()(Code) Returns a set view of the entries of this map. The returned set is a view, so changes to this map are reflected by the returned set and vice versa. All elements of the returned set implements java.util.Map.Entry java.util.Map.Entry . a set view of the entries of this map. equals public boolean equals(Object obj)(Code) Indicates whether this map is equal to some object. Parameters:   obj - the object with which to compare this map. true if this map is equal to thespecified object; returns falseotherwise. get public Object get(Object key)(Code) Maps a specified key to a value. Returns null if no mapping exists for the specified key. Parameters:   key - the key to map to a value. the value that the specified key maps to, ornull, if no such mapping exists. throws:   NullPointerException - if key is null. throws:   ClassCastException - if key is not of class Float Float. hashCode public int hashCode()(Code) Returns a hash code value for this map. The hash code returned is that of the underlying map. a hash code value for this map. isEmpty public boolean isEmpty()(Code) Indicates whether this map is empty. true if this map is empty; returnsfalse otherwise. keySet public Set keySet()(Code) Returns a set view of the keys of this map. Removals from the returned set removes the corresponding entries in this map. Changes to the map are reflected in the set. All elements if the returned set is of class Float Float . a set view of the keys of this map. put public Object put(Object key, Object value)(Code) Adds a mapping from a specified key to a specified value to this map. If a mapping already exists for the specified key it is overwritten by the new mapping. The mapping is added to the underlying map. Parameters:   key - the key of the mapping to add to this map. Parameters:   value - the value of the mapping to add to this map. the old value if amapping from the specified key already existedin this map; returns null otherwise. throws:   UnsupportedOperationException - if the operation is not supported by this map. throws:   NullPointerException - if key is null;if value is null. throws:   ClassCastException - if key is not of class Float Float. putAll public void putAll(Map map)(Code) Adds all mappings from a specified map to this map. Any existing mappings whose keys collide with a new mapping is overwritten by the new mapping. The mappings are added to the underlying map. Parameters:   map - the map whose mappings to add to this map. throws:   NullPointerException - if map is null. throws:   UnsupportedOperationException - if the operation is not supported by this map. throws:   NullPointerException - if a key in map is null. throws:   ClassCastException - if a key in map is not of class Float Float. remove public Object remove(Object key)(Code) Removes the mapping from a specified key from this map. The mapping is removed from the underlying map. Parameters:   key - the key whose mapping to remove from this map. the old value if amapping from the specified key already existedin this map; returns null otherwise. throws:   UnsupportedOperationException - if the operation is not supported by the underlying map. size public int size()(Code) Returns the size of this map. The size is defined as the number of mappings from keys to values. The size is that of the underlying map. the size of this map. values public Collection values()(Code) Returns a collection view of the values in this map. The collection is not modifiable, but changes to the map are reflected in the collection. a collection view of the values in this map.
