LazyMap

java.lang.Object

org.tweetyproject.arg.adf.util.LazyMap<K,V>

Type Parameters:: K - the key; V - the value

All Implemented Interfaces:: Map<K,V>

public final class LazyMap<K,V> extends Object implements Map<K,V>

Lazily computes missing values. If a key is mapped to null, the value is computed by the provided function on its first access.
