Method Detail

makeUnmodifiableback to summary
public void makeUnmodifiable()

Makes the MultiHashtable unmodifiable. This method allows modules to set the table as "read-only" so that only query operation, that is maps, is allowed. Any attempts to modify the returned map result in an UnsupportedOperationException.

mapsback to summary
public V maps(K key, V value)

Maps a key to a value in a set that is associated with the specified key. The mapping is performed by evaluating whether an item in the set equals the specified value.

Parameters
key:K

key with which the specified value is to be associated

value:V

value in a set that is associated with the specified key

Returns:V

the item in the set if a match is found.

putback to summary
public Set<V> put(K key, V value)

Associates the specified key with a set of values. If the map previously contained a mapping for the key, the value is added to the set.

Parameters
key:K

key with which the specified value is to be associated

value:V

value to be added to a set that is associated with the specified key

Returns:Set<V>

the set that is associated with the specified key.

Exceptions
UnsupportedOperationException:
is the MultiHashtable is not modifiable.
