 @NonNull
 FactoryPools.Factory<T> factory)

Returns a non-thread safe Pools.Pool that never returns null from Pools.Pool.acquire() and that contains objects of the type created by the given FactoryPools.Factory with the given maximum size.

If the pool is empty when Pools.Pool.acquire() is called, the given FactoryPools.Factory will be used to create a new instance.

Type Parameters:

T - The type of object the pool will contains.

threadSafe

@NonNull
public static <T extends FactoryPools.Poolable>
androidx.core.util.Pools.Pool<T> threadSafe(int size,
 @NonNull
 FactoryPools.Factory<T> factory)

Identical to threadSafe(int, Factory, Resetter) except no action is taken when an instance is returned to the pool.

threadSafe

@NonNull
public static <T extends FactoryPools.Poolable>
androidx.core.util.Pools.Pool<T> threadSafe(int size,
 @NonNull
 FactoryPools.Factory<T> factory,
 @NonNull
 FactoryPools.Resetter<T> resetter)

Returns a new thread safe Pools.Pool that never returns null from Pools.Pool.acquire() and that contains objects of the type created by the given FactoryPools.Factory with the given maximum size.

If the pool is empty when Pools.Pool.acquire() is called, the given FactoryPools.Factory will be used to create a new instance.

Each time an instance is returned to the pool resetter will be called with the given instance.

Type Parameters:

T - The type of object the pool will contains.

@NonNull
public static <T>
androidx.core.util.Pools.Pool<List<T>> threadSafeList()

Returns a new Pools.Pool that never returns null and that contains Lists of a specific generic type with a standard maximum size of 20.

If the pool is empty when Pools.Pool.acquire() is called, a new List will be created.

Type Parameters:

T - The type of object that the Lists will contain.

threadSafeList

@NonNull
public static <T>
