    • computeIfAbsent

      public V computeIfAbsent​(short key, java.util.function.IntFunction<? extends V> mappingFunction)
      Description copied from interface: Short2ReferenceMap
      If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.

      Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the mappingFunction cannot return null. If such a behavior is needed, please use the corresponding nullable version.

      Specified by:
      computeIfAbsent in interface Short2ReferenceMap<V>
      Parameters:
      key - key with which the specified value is to be associated.
      mappingFunction - the function to compute a value.
      Returns:
      the current (existing or computed) value associated with the specified key.
      See Also:
      Map.computeIfAbsent(Object, java.util.function.Function)

    • computeIfAbsent

      public V computeIfAbsent​(short key, it.unimi.dsi.fastutil.shorts.Short2ReferenceFunction<? extends V> mappingFunction)
      Description copied from interface: Short2ReferenceMap
      If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.

      This version of computeIfAbsent() uses a type-specific version of fastutil's Function. Since Function has a containsKey() method, it is possible to avoid adding a key by having containsKey() return false for that key.

      Specified by:
      computeIfAbsent in interface Short2ReferenceMap<V>
      Parameters:
      key - key with which the specified value is to be associated.
      mappingFunction - the function to compute a value.
      Returns:
      the current (existing or computed) value associated with the specified key.
      See Also:
      Map.computeIfAbsent(Object, java.util.function.Function)

    • computeIfPresent

      public V computeIfPresent​(short key, java.util.function.BiFunction<? super java.lang.Short,​? super V,​? extends V> remappingFunction)
      Description copied from interface: Short2ReferenceMap
      If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.
      Specified by:
      computeIfPresent in interface Short2ReferenceMap<V>
      Parameters:
      key - key with which the specified value is to be associated.
      remappingFunction - the function to compute a value.
      Returns:
      the new value associated with the specified key, or the default return value if none.
      See Also:
      Map.computeIfPresent(Object, java.util.function.BiFunction)

    • compute

      public V compute​(short key, java.util.function.BiFunction<? super java.lang.Short,​? super V,​? extends V> remappingFunction)
      Description copied from interface: Short2ReferenceMap
      Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

      If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

      Specified by:
      compute in interface Short2ReferenceMap<V>
      Parameters:
      key - key with which the specified value is to be associated.
      remappingFunction - the function to compute a value.
      Returns:
      the new value associated with the specified key, or the default return value if none.

      Map.compute(Object, java.util.function.BiFunction)

    • merge

      public V merge​(short key, V value, java.util.function.BiFunction<? super V,​? super V,​? extends V> remappingFunction)
      Description copied from interface: Short2ReferenceMap
      If the specified key is not already associated with a value, associates it with the given value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.
      Specified by:
      merge in interface Short2ReferenceMap<V>
      Parameters:
      key - key with which the resulting value is to be associated.
      value - the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.
      remappingFunction - the function to recompute a value if present.
      Returns:
      the new value associated with the specified key, or the default return value if no value is associated with the key.
