Method Detail
-
put
PMap<K,V> put(K key, V value)
- Returns:
- new map with added key-value pair, or this if map already contains given key-value pair
-
remove
PMap<K,V> remove(K key)
- Returns:
- new map with removed key, or this if map does not contain given key
-
forEach
void forEach(BiConsumer<K,V> action)
Performs the given action for each entry in this map until all entries have been processed or the action throws an exception.
-
isEmpty
boolean isEmpty()
- Returns:
- true if this map contains no elements
-
toString
String toString()
The string representation consists of a list of key-value mappings in the ascending order of hash codes of keys. If two keys have same hash code, then their relative order is arbitrary, but stable.
