public interface LabeledIntMap extends Serializable
Realizes the map Label-->int

The semantics of a set of labeled values is defined in the paper “The Dynamic Controllability of Conditional STNs with Uncertainty” by Hunsberger, Luke, Roberto Posenato, and Carlo Combi. 2012. https://arxiv.org/abs/1212.2005.

All methods managing a single labeled value have to make a defensive copy of the label to guarantee that the label insert/get is a copy of the label given/requested.

All methods managing a bundle of labeled values do not have to make a defensive copy for performance reasons.

  • Field Details

    • entryComparator

      static final Comparator<it.unimi.dsi.fastutil.objects.Object2IntMap.Entry<Label>> entryComparator
      A natural comparator for Entry<Label>. It orders the elements considering the alphabetical order of labels.

    • serialVersionUID

      static final long serialVersionUID
      Serial UID

  • Method Details

    • alreadyRepresents

      boolean alreadyRepresents(Label newLabel, int newValue)
      Parameters:
      newLabel - a Label object.
      newValue - the new value.
      Returns:
      true if the current map can represent the value. In a positive case, the addition of the element does not change the map. If it returns false, then adding the value to the map would modify the map.

    • clear

      void clear()
      Remove all entries from the map.
      See Also:

    • entrySet

      it.unimi.dsi.fastutil.objects.ObjectSet<it.unimi.dsi.fastutil.objects.Object2IntMap.Entry<Label>> entrySet()
      The set of all map entries. The set is a view of the map. A modification of the map is reflected in the entries of the returned set.
      If it is necessary to scan all the entries to modify the map, the only right way is to consider the keys returned by keySet() and use methods like remove(Label) and/or put(Label, int).
      Returns:
      The set of all map entries.
      See Also:

    • get

      int get(Label l)
      Parameters:
      l - an Label object.
      Returns:
      the value associated to l if it exists, Constants.INT_NULL otherwise.

    • getMaxValue

      default int getMaxValue()
      Returns:
      the maximum int value present in the set if the set is not empty; Constants.INT_NULL otherwise.

    • getMaxValueSubsumedBy

      default int getMaxValueSubsumedBy(Label l)
      Returns the value associated with the l if it exists, otherwise the maximal value among all labels consistent with l.
      Parameters:
      l - If it is null, Constants.INT_NULL is returned.
      Returns:
      the value associated with the l if it exists or the maximal value among values associated with labels consistent with l. If no labels are consistent by l, Constants.INT_NULL is returned.

    • getMinLabeledValue

      default it.unimi.dsi.fastutil.objects.Object2IntMap.Entry<Label> getMinLabeledValue()
      Returns:
      the minimum entry in the set if the set is not empty; an entry with Constants.INT_NULL otherwise.

    • getMinValue

      default int getMinValue()
      Returns:
      the minimum int value present in the set if the set is not empty; Constants.INT_NULL otherwise.

    • getMinValueAmongLabelsWOUnknown

      default int getMinValueAmongLabelsWOUnknown()
      Returns:
      the minimum value among all labeled values having a label without unknown literals.

    • getMinValueConsistentWith

      default int getMinValueConsistentWith(Label l)
      Returns the value associated with the l if it exists, otherwise the minimal value among all labels consistent with l.
      Parameters:
      l - If it is null, Constants.INT_NULL is returned.
      Returns:
      the value associated with the l if it exists or the minimal value among values associated with labels consistent with l. If no labels are consistent by l, Constants.INT_NULL is returned.

    • getMinValueSubsumedBy

      default int getMinValueSubsumedBy(Label l)
      Returns the minimal value among those associated with labels subsumed by l if it exists, Constants.INT_NULL otherwise.
      Parameters:
      l - If it is null, Constants.INT_NULL is returned.
      Returns:
      minimal value among those associated with labels subsumed by l if it exists, Constants.INT_NULL otherwise.

    • isEmpty

      boolean isEmpty()
      Returns:
      true if the map has no elements.

    • keySet

      it.unimi.dsi.fastutil.objects.ObjectSet<Label> keySet()
      A copy of all labels in the map.

      The returned set must not be connected to the map.

      The semantics of this method is different from the Map.keySet()!

      It can cost time and memory because it duplicates all the keys of the map.

      This method allows one to scan all the keys of the map, even if during the scan, some key of the map is removed.

      It is important to modify this map using only the method remove(Label).

      Method entrySet() returns a view of the entries of the map. Therefore, it cannot be used to scan or modify the map.

      Returns:
      a copy of all labels in the map.

    • newInstance

      LabeledIntMap newInstance()
      Factory
      Returns:
      an object of type LabeledIntMap.

    • newInstance

      LabeledIntMap newInstance(boolean optimize)
      Factory
      Parameters:
      optimize - true for having the label as short as possible, false otherwise. For example, the set {(0, ¬C), (1, C)} is represented as {(0, ⊡), (1, C)} if this parameter is true.
      Returns:
      an object of type LabeledIntMap.

    • newInstance

      LabeledIntMap newInstance(LabeledIntMap lim)
      Factory
      Parameters:
      lim - a map to clone.
      Returns:
      an object of type LabeledIntMap.

    • newInstance

      LabeledIntMap newInstance(LabeledIntMap lim, boolean optimize)
      Factory
      Parameters:
      lim - a map to clone.
      optimize - true for having the label as short as possible, false otherwise.
      For example, the set {(0, ¬C), (1, C)} is represented as {(0, ⊡), (1, C)} if this parameter is true.
      Returns:
      an object of type LabeledIntMap.

    • put

      boolean put(Label l, int i)
      Put a label with value i if label l is not null and there is no labeled value in the set with label l, or it is present but with a value higher than l.

      Not mandatory: the method can remove or modify other labeled values of the set to minimize the labeled values present, guaranteeing that no info is lost.

      Parameters:
      l - a non-null label.
      i - a not Constants.INT_NULL value.
      Returns:
      true if (l,i) has been inserted. Since an insertion can remove more than one redundant labeled value, it is nonsensical to return "the old value" as expected from a classical put method.

    • putAll

      default void putAll(LabeledIntMap inputMap)
      Put all elements of `inputMap` into the current one without making a defensive copy.
      Parameters:
      inputMap - an object.
      See Also:

    • putForcibly

      void putForcibly(Label l, int i)
      Put the labeled value without any control. It is dangerous, but it can help in some cases.
      Parameters:
      l - a Label object.
      i - the new value.

    • remove

      int remove(@Nonnull Label l)
      Remove the label l from the map. If the l is not present, it does nothing.
      Parameters:
      l - a non-null label.
      Returns:
      the previous value associated with l, or Constants.INT_NULL if there was no mapping for l.

    • size

      int size()
      Returns:
      the number of labeled values (value with empty label included).
      See Also:

    • unmodifiable

      LabeledIntMap.LabeledIntMapView unmodifiable()
      Returns:
      a read-only view of this.

    • values

      it.unimi.dsi.fastutil.ints.IntSet values()
      Returns:
      the set of all integer values present in the map as an ordered list.
