Method Details

getDiff

public static <T,
M> IngredientCollectionDiff<T,M> getDiff(IngredientComponent<T,M> ingredientComponent,
 @Nullable
 IngredientCollectionPrototypeMap<T,M> oldInstancesCache,
 IngredientCollectionPrototypeMap<T,M> newInstancesCache,
 Iterator<T> newInstances)

Calculate a diff between oldInstancesCache - newInstances, and produce a diff. Additionally, this will populate newInstancesCache with all instances from newInstances.

Type Parameters:

T - The instance type.

M - The matching condition parameter.

Parameters:

ingredientComponent - The ingredient component type.

oldInstancesCache - The collection of instances to take the difference from.

newInstancesCache - An empty collection to store our new instances from newInstances. This should be used as oldInstancesCache parameter on the next call. This map MUST accept negative instances. of this method.

newInstances - The new instances to calculate the difference with.

Returns:

The resulting diff between oldInstancesCache and newInstances.

applyDiff

public static <T,
M> void applyDiff(IngredientComponent<T,M> ingredientComponent,
 IngredientCollectionDiff<T,M> diff,
 IIngredientCollectionMutable<T,M> collection)

Apply the given diff to the given collection.

Type Parameters:

T - The instance type.

M - The matching condition parameter.

Parameters:

ingredientComponent - The ingredient component type.

diff - The diff to apply.

collection - The collection to apply the diff to.
