All Implemented Interfaces:

Serializable, Cloneable, Map

Enclosing class:

LocaleConvertUtilsBean

private static class LocaleConvertUtilsBean.DelegateFastHashMap
extends FastHashMap

FastHashMap implementation that uses WeakReferences to overcome memory leak problems. This is a hack to retain binary compatibility with previous releases (where FastHashMap is exposed in the API), but use WeakHashMap to resolve memory leaks.

LocaleConvertUtilsBean.DelegateFastHashMap

private LocaleConvertUtilsBean.DelegateFastHashMap(Map map)

Method Detail

clear

public void clear()

Description copied from class: FastHashMap

Remove all mappings from this map.

Specified by:

clear in interface Map

Overrides:

clear in class FastHashMap

containsKey

public boolean containsKey(Object key)

Description copied from class: FastHashMap

Return true if this map contains a mapping for the specified key.

Specified by:

containsKey in interface Map

Overrides:

containsKey in class FastHashMap

Parameters:

key - the key to be searched for

Returns:

true if the map contains the key

containsValue

public boolean containsValue(Object value)

Description copied from class: FastHashMap

Return true if this map contains one or more keys mapping to the specified value.

Specified by:

containsValue in interface Map

Overrides:

containsValue in class FastHashMap

Parameters:

value - the value to be searched for

Returns:

true if the map contains the value

entrySet

public Set entrySet()

Description copied from class: FastHashMap

Return a collection view of the mappings contained in this map. Each element in the returned collection is a Map.Entry.

Specified by:

entrySet in interface Map

Overrides:

entrySet in class FastHashMap

Returns:

the set of map Map entries

equals

public boolean equals(Object o)

Description copied from class: FastHashMap

Compare the specified object with this list for equality. This implementation uses exactly the code that is used to define the list equals function in the documentation for the Map.equals method.

Specified by:

equals in interface Map

Overrides:

equals in class FastHashMap

Parameters:

o - the object to be compared to this list

Returns:

true if the two maps are equal

get

public Object get(Object key)

Description copied from class: FastHashMap

Return the value to which this map maps the specified key. Returns null if the map contains no mapping for this key, or if there is a mapping with a value of null. Use the containsKey() method to disambiguate these cases.

Specified by:

get in interface Map

Overrides:

get in class FastHashMap

Parameters:

key - the key whose value is to be returned

Returns:

the value mapped to that key, or null

hashCode

public int hashCode()

Description copied from class: FastHashMap

Return the hash code value for this map. This implementation uses exactly the code that is used to define the list hash function in the documentation for the Map.hashCode method.

Specified by:

hashCode in interface Map

Overrides:

hashCode in class FastHashMap

Returns:

suitable integer hash code

isEmpty

public boolean isEmpty()

Description copied from class: FastHashMap

Return true if this map contains no mappings.

Specified by:

isEmpty in interface Map

Overrides:

isEmpty in class FastHashMap

Returns:

is the map currently empty

keySet

public Set keySet()

Description copied from class: FastHashMap

Return a set view of the keys contained in this map.

Specified by:

keySet in interface Map

Overrides:

keySet in class FastHashMap

Returns:

the set of the Map's keys

put

public Object put(Object key,
                  Object value)

Description copied from class: FastHashMap

Associate the specified value with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced and returned.

Specified by:

put in interface Map

Overrides:

put in class FastHashMap

Parameters:

key - the key with which the value is to be associated

value - the value to be associated with this key

Returns:

the value previously mapped to the key, or null

putAll

public void putAll(Map m)

Description copied from class: FastHashMap

Copy all of the mappings from the specified map to this one, replacing any mappings with the same keys.

Specified by:

putAll in interface Map

Overrides:

putAll in class FastHashMap

Parameters:

m - the map whose mappings are to be copied

remove

public Object remove(Object key)

Description copied from class: FastHashMap

Remove any mapping for this key, and return any previously mapped value.

Specified by:

remove in interface Map

Overrides:

remove in class FastHashMap

Parameters:

key - the key whose mapping is to be removed

Returns:

the value removed, or null

size

public int size()

Description copied from class: FastHashMap

Return the number of key-value mappings in this map.

Specified by:

size in interface Map

Overrides:
