Method Detail

readableMap

public static <K,V> IterableMap<K,V> readableMap(Get<K,V> get)

Get the specified Get as an instance of IterableMap. If get implements IterableMap directly, no conversion will take place. If get implements Map but not IterableMap it will be decorated. Otherwise an Unmodifiable IterableMap will be returned.

Type Parameters:

K - the key type

V - the value type

Parameters:

get - to wrap, must not be null

Returns:

IterableMap

Throws:

NullPointerException - if the argument is null

writableMap

public static <K,V> Map<K,V> writableMap(Put<K,V> put)

Get the specified Put as an instanceof Map. If put implements Map directly, no conversion will take place. Otherwise a write-only Map will be returned. On such a Map it is recommended that the result of #put(K, V) be discarded as it likely will not match V at runtime.

Type Parameters:

K - the key type

V - the element type

Parameters:

put - to wrap, must not be null

Returns:

Map

Throws:

NullPointerException - if the argument is null
