Class IngredientPositionsIndex<T,M>

java.lang.Object
org.cyclops.integrateddynamics.core.network.IngredientPositionsIndex<T,M>
Type Parameters:
T - An instance type.
M - The matching condition parameter.
All Implemented Interfaces:
Iterable<T>, org.cyclops.cyclopscore.ingredient.collection.IIngredientCollection<T,M>, org.cyclops.cyclopscore.ingredient.collection.IIngredientCollectionLike<T,M,T>, IIngredientPositionsIndex<T,M>
public class IngredientPositionsIndex<T,M> extends Object implements IIngredientPositionsIndex<T,M>
An index that maps ingredients to positions that contain that instance. Positions are stored together with their priorities. This makes it possible for instances of this class to guarantee that all returned iterators maintain priority order.

    • IngredientPositionsIndex

      public IngredientPositionsIndex(org.cyclops.commoncapabilities.api.ingredient.IngredientComponent<T,M> component)

  • Method Details

    • getPrototype

      protected T getPrototype(T instance)

    • getInternalPriority

      protected int getInternalPriority(PrioritizedPartPos pos)

    • getNonEmptyPositions

      public Iterator<PartPos> getNonEmptyPositions()
      Specified by:
      getNonEmptyPositions in interface IIngredientPositionsIndex<T,M>
      Returns:
      Get all positions that are not empty.

    • getPositions

      public Iterator<PartPos> getPositions(T instance, M matchFlags)
      Description copied from interface: IIngredientPositionsIndex
      Get all positions that have an instance that contain the given instance.
      Specified by:
      getPositions in interface IIngredientPositionsIndex<T,M>
      Parameters:
      instance - An instance to match.
      matchFlags - Instance match conditions.
      Returns:
      The positions.

    • iteratePrioritized

      protected Iterator<PartPos> iteratePrioritized(Function<org.cyclops.cyclopscore.ingredient.collection.IIngredientMapMutable<T, M, it.unimi.dsi.fastutil.objects.ObjectOpenHashSet<PartPos>>, Iterator<PartPos>> positionsGetter)
      Lazily iterate over the positions of all priority levels, in priority order, without duplicates. Iteration is lazy because callers commonly stop iterating as soon as they have found a usable position.
      Parameters:
      positionsGetter - A callback for iterating over the matching positions within one priority level.
      Returns:
      An iterator over all matching positions.

    • distinct

      protected Iterator<PartPos> distinct(Iterator<PartPos> positions)
      Filter out duplicate positions, as the same position can hold multiple instances.
      Parameters:
      positions - An iterator over positions.
      Returns:
      An iterator over distinct positions.

    • addPosition

      public void addPosition(T instance, PrioritizedPartPos pos)
      Description copied from interface: IIngredientPositionsIndex
      Indicate that the given position contains the given position.
      Specified by:
      addPosition in interface IIngredientPositionsIndex<T,M>
      Parameters:
      instance - An instance.
      pos - A position.

    • createPositionsMap

      protected org.cyclops.cyclopscore.ingredient.collection.IIngredientMapMutable<T, M, it.unimi.dsi.fastutil.objects.ObjectOpenHashSet<PartPos>> createPositionsMap()
      Create a map for storing the positions of one priority level. Instances are classified by their first category type when the component has more than one, so that lookups by that category don't have to scan over all indexed instances.
      Returns:
      A new positions map.

    • removePosition

      public void removePosition(T instance, PrioritizedPartPos pos)
      Description copied from interface: IIngredientPositionsIndex
      Indicate that the given instance is removed from the given position. This will not necessarily remove the given position, only if the total instance quantity becomes zero.
      Specified by:
      removePosition in interface IIngredientPositionsIndex<T,M>
      Parameters:
      instance - An instance.
      pos - A position.

    • getQuantity

      public long getQuantity(T instance)
      Description copied from interface: IIngredientPositionsIndex
      Get the available quantity for the given instance.
      Specified by:
      getQuantity in interface IIngredientPositionsIndex<T,M>
      Parameters:
      instance - An instance to match.
      Returns:
      The indexed quantity.
