This class does not have a constructor, so you cannot create it directly.
To get an instance of this class, use one of the subclass constructors.
clear()
:
void
Clears the map of all objects.
containsKey(key
:
Object)
:
boolean
Identifies if this map contains an element identfied by the specified key.
containsValue(value
:
Object)
:
boolean
Identifies if this map contains an element identfied by the specified value.
get(key
:
Object)
:
Object
Returns the object associated with the key or null.
isEmpty()
:
boolean
Identifies if this map is empty.
keySet()
:
Set
Returns a set of the map's keys.
put(key
:
Object, value
:
Object)
:
Object
Puts the specified value into the map using the specified key to identify it.
putAll(other
:
Map)
:
void
Copies all of the objects inside the specified map into this map.
remove(key
:
Object)
:
Object
Removes the object from the map that is identified by the key.
clear
clear()
:
void
Clears the map of all objects.
containsKey
containsKey(key
:
Object)
:
boolean
Identifies if this map contains an element identfied
by the specified key.
Parameters:
key
-
the key to use.
Returns:
true if this map contains an element whose key is equal to the specified key.
containsValue
containsValue(value
:
Object)
:
boolean
Identifies if this map contains an element identfied
by the specified value.
Parameters:
value
-
the value to use.
Returns:
true if this map contains an element whose value is equal to the specified value.
entrySet
Returns a set of the map's entries. The returned set is actually a view to the entries of this map.
Returns:
a set of the map's entries.
get
Returns the object associated with the key or null.
Parameters:
key
-
the key to use.
Returns:
the object associated with the key or null.
getLength
REturns the size of the map. This is a bean attribute method and
supports the access to the collections
length similar to a ECMA array, such as 'products.length'.
Returns:
the number of objects in the map.
isEmpty
isEmpty()
:
boolean
Identifies if this map is empty.
Returns:
true if the map is empty, false otherwise.
keySet
Returns a set of the map's keys. The returned set is actually a view to the keys of this map.
Returns:
a set of the map's keys.
put
Puts the specified value into the map using the
specified key to identify it.
Parameters:
key
-
the key to use to identify the value.
value
-
the object to put into the map.
Returns:
previous value associated with specified key, or null if there was no mapping for key.
putAll
putAll(other
:
Map)
:
void
Copies all of the objects inside the specified map
into this map.
Parameters:
other
-
the map whose contents are copied into this map.
remove
Removes the object from the map that is identified by the key.
Parameters:
key
-
the key that identifies the object to remove.
Returns:
the removed object or null.
size
Returns the size of the map.
Returns:
the number of objects in the map.
values
Returns a collection of the values contained in this map.
API Versioned:
No longer available as of version 16.1.
Returns an independent modifiable collection holding all values.
Returns:
a collection of the values contained in this map
values
Returns a collection of the values contained in this map.
API Versioned:
From version 16.1.
Returns a view on the values of this map like keySet() and entrySet() do. Former version returned a shallow copy of this.
Returns:
a collection of the values contained in this map
