Constructor Detail

AWMap_AribaHashtable

public AWMap_AribaHashtable()

Creates a new AWMap_AribaHashtable object.

Method Detail

clear

public void clear(Object receiver)

Removes all mappings from the given map.

Specified by:

clear in class AWMap

Parameters:

receiver - map implementation

containsKey

public boolean containsKey(Object receiver,
                           Object key)

Returns true if the given map contains a mapping for the specified key.

Specified by:

containsKey in class AWMap

Parameters:

receiver - map implementation

key - key whose presence in map is to be tested

containsValue

public boolean containsValue(Object receiver,
                             Object value)

Returns true if the given 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)).

Specified by:

containsValue in class AWMap

Parameters:

receiver - map implementation

value - value whose presence in map is to be tested

Returns:

true if map maps one or more keys to the specified value

get

public Object get(Object receiver,
                  Object key)

Returns the value to which the given map maps the specified key. Returns null if the map contains no mapping for this key.

Specified by:

get in class AWMap

Parameters:

receiver - map implementation

key - key whose associated value is to be returned

Returns:

value to which map maps the specified key, or null if the map contains no mapping for this key

isEmpty

public boolean isEmpty(Object receiver)

Returns true if the map contains no key-value mappings.

Specified by:

isEmpty in class AWMap

Parameters:

receiver - map implementation

Returns:

true if map contains no key-value mappings

keys

public Iterator keys(Object receiver)

Returns an enumeration of the keys in the map.

Specified by:

keys in class AWMap

Parameters:

receiver - map implementation

Returns:

enumeration of the keys in the map

put

public Object put(Object receiver,
                  Object key,
                  Object value)

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

Specified by:

put in class AWMap

Parameters:

receiver - map implementation

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

value - value to be associated with the specified key

Returns:

previous value associated with specified key, or null if there was no mapping for key

remove

public Object remove(Object receiver,
                     Object key)

Removes the mapping for this key from this map if present.

Specified by:

remove in class AWMap

Parameters:

receiver - map implementation

key - key whose mapping is to be removed from the map

Returns:

previous value associated with specified key, or null if there was no mapping for key

size

public int size(Object receiver)

Returns the number of key-value mappings in the map.

Specified by:

size in class AWMap

Parameters:

receiver - map implementation

Returns:

number of key-value mappings in map

values

public Iterator values(Object receiver)

Returns an enumeration of the values contained in the map.

Specified by:

values in class AWMap

Parameters:

receiver - map implementation

Returns:

an enumeration of the values contained in the map
