 org.jfree.util.HashNMap
| HashNMap | | public class HashNMap implements Serializable,Cloneable(Code) | | The HashNMap can be used to store multiple values by a single key value. The
values stored can be retrieved using a direct query or by creating an
enumeration over the stored elements.

| Constructor Summary | |
| public | HashNMap()
Default constructor. |
| Method Summary | |
| public boolean | add(Object key, Object val)
Adds a new key/value pair into this map. | | public void | clear()
Clears all keys and values of this map. | | public Object | clone()

Tests whether this map contains the given key or value.
Parameters:
value - the value. | | public boolean | containsKey(Object key)
Tests whether this map contains the given key.
Parameters:
key - the key. | | public boolean | containsValue(Object value)
Tests whether this map contains the given value.
Parameters:
value - the value. | | public boolean | containsValue(Object key, Object value)
Tests whether this map contains the given value. | | protected List | createList()
Returns a new empty list. | | public Object | get(Object key, int n)
Retrieves the n-th value registered for an key or null if there was no
such key in the list. | | public Iterator | getAll(Object key)
Returns an iterator over all elements registered to the given key.
Parameters:
key - the key. | | public Object | getFirst(Object key)
Retrieves the first value registered for an key or null if there was no
such key in the list.
Parameters:
key - the key. | | public int | getValueCount(Object key)
Returns the number of elements registered with the given key.
Parameters:
key - the key. | | public Set | keySet()
Returns all registered keys as set. | | public Iterator | keys()
Returns all registered keys as an enumeration. | | public boolean | put(Object key, Object val)
Inserts a new key/value pair into the map. | | public boolean | remove(Object key, Object value)
Removes the key/value pair from the map. | | public void | removeAll(Object key)
Removes all elements for the given key. | | public Object[] | toArray(Object key, Object[] data)
Returns the contents for the given key as object array. | | public Object[] | toArray(Object key)
Returns the contents for the given key as object array. |
| HashNMap | | public HashNMap()(Code) | | Default constructor.
|
| add | | public boolean add(Object key, Object val)(Code) | | Adds a new key/value pair into this map. If the key is not yet in the
map, it gets added to the map and the call is equal to
put(Object,Object).
Parameters:
key - the key.
Parameters:
val - the value. true, if the value has been added, false otherwise |
| clear | | public void clear()(Code) | | Clears all keys and values of this map.
|
| contains | | public boolean contains(Object value)(Code) | | Tests whether this map contains the given key or value.
Parameters:
value - the value. true if the key or value is contained in the map |
| containsKey | | public boolean containsKey(Object key)(Code) | | Tests whether this map contains the given key.
Parameters:
key - the key. true if the key is contained in the map |
| containsValue | | public boolean containsValue(Object value)(Code) | | Tests whether this map contains the given value.
Parameters:
value - the value. true if the value is registered in the map for an key. |
| containsValue | | public boolean containsValue(Object key, Object value)(Code) | | Tests whether this map contains the given value.
Parameters:
value - the value.
Parameters:
key - the key under which to find the value true if the value is registered in the map for an key. |
| createList | | protected List createList()(Code) | | Returns a new empty list.
A new empty list. |
| get | | public Object get(Object key, int n)(Code) | | Retrieves the n-th value registered for an key or null if there was no
such key in the list. An index out of bounds exception is thrown if
there are less than n elements registered to this key.
Parameters:
key - the key.
Parameters:
n - the index. the object. |
| getAll | | public Iterator getAll(Object key)(Code) | | Returns an iterator over all elements registered to the given key.
Parameters:
key - the key. an iterator. |
| getFirst | | public Object getFirst(Object key)(Code) | | Retrieves the first value registered for an key or null if there was no
such key in the list.
Parameters:
key - the key. the value. |
| getValueCount | | public int getValueCount(Object key)(Code) | | Returns the number of elements registered with the given key.
Parameters:
key - the key. the number of element for this key, or 0 if there are no elementsregistered. |
| keySet | | public Set keySet()(Code) | | Returns all registered keys as set.
a set of keys. |
| keys | | public Iterator keys()(Code) | | Returns all registered keys as an enumeration.
an enumeration of the keys. |
| put | | public boolean put(Object key, Object val)(Code) | | Inserts a new key/value pair into the map. If such a pair already
exists, it gets replaced with the given values.
Parameters:
key - the key.
Parameters:
val - the value. A boolean. |
| remove | | public boolean remove(Object key, Object value)(Code) | | Removes the key/value pair from the map. If the removed entry was the
last entry for this key, the key gets also removed.
Parameters:
key - the key.
Parameters:
value - the value. true, if removing the element was successfull, false otherwise. |
| removeAll | | public void removeAll(Object key)(Code) | | Removes all elements for the given key.
Parameters:
key - the key. |
| toArray | | public Object[] toArray(Object key, Object[] data)(Code) | | Returns the contents for the given key as object array. If there were
no objects registered with that key, an empty object array is returned.
Parameters:
key - the key.
Parameters:
data - the object array to receive the contents. the contents. |
| toArray | | public Object[] toArray(Object key)(Code) | | Returns the contents for the given key as object array. If there were
no objects registered with that key, an empty object array is returned.
Parameters:
key - the key. the contents. |
