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:

builder

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

Creates a new empty builder for building immutable map.

Returns:

a new empty builder
