Method Detail

copyOf

public static <K,V> Map<K,V> copyOf(Map<K,V> map)

Creates an immutable map. A copy of the given map is used. As a result, it is safe to modify the source map afterwards.

Parameters:

map - the given map

Returns:

an immutable map

of

public static <K,V> Map<K,V> of(K key,
                                            V value)

Creates an immutable singleton instance.

Parameters:

key -

value -

Returns:

collector

public static <T,K,V> org.jboss.weld.util.collections.ImmutableMap.ImmutableMapCollector<T,K,V> collector(Function<T,K> keyMapper,
                                                                                                                                  Function<T,V> valueMapper)

Returns a collector that accumulates elements into an immutable map.

Duplicate mappings are not merged - the old value is replaced.

Parameters:

keyMapper -

valueMapper -

Returns:

collector

builder

public static <K,V> ImmutableMap.Builder<K,V> builder()

Creates a new empty builder for building immutable map.

Returns:

a new empty builder
