Package-level declarations

Types

class MutableObjectFloatMap<K>(initialCapacity: Int = DefaultScatterCapacity) : ObjectFloatMap<K>

MutableObjectFloatMap is a container with a MutableMap-like interface for keys with reference types and Float primitives for values.

MutableScatterMap

class MutableScatterMap<K, V>(initialCapacity: Int = DefaultScatterCapacity) : ScatterMap<K, V>

MutableScatterMap is a container with a Map-like interface based on a flat hash table implementation (the key/value mappings are not stored by nodes but directly into arrays). The underlying implementation is designed to avoid all allocations on insertion, removal, retrieval, and iteration. Allocations may still happen on insertion when the underlying storage needs to grow to accommodate newly added entries to the table. In addition, this implementation minimizes memory usage by avoiding the use of separate objects to hold key/value pairs.

MutableScatterSet

class MutableScatterSet<E>(initialCapacity: Int = DefaultScatterCapacity) : ScatterSet<E>

MutableScatterSet is a container with a MutableSet-like interface based on a flat hash table implementation. The underlying implementation is designed to avoid all allocations on insertion, removal, retrieval, and iteration. Allocations may still happen on insertion when the underlying storage needs to grow to accommodate newly added elements to the set.

ObjectFloatMap

sealed class ObjectFloatMap<K>

ObjectFloatMap is a container with a Map-like interface for keys with reference types and Float primitives for values.

ObjectList

typealias ObjectList<T> = List<T>

ScatterMap

sealed class ScatterMap<K, V>

ScatterMap is a container with a Map-like interface based on a flat hash table implementation (the key/value mappings are not stored by nodes but directly into arrays). The underlying implementation is designed to avoid all allocations on insertion, removal, retrieval, and iteration. Allocations may still happen on insertion when the underlying storage needs to grow to accommodate newly added entries to the table. In addition, this implementation minimizes memory usage by avoiding the use of separate objects to hold key/value pairs.

ScatterSet

sealed class ScatterSet<E>

ScatterSet is a container with a Set-like interface based on a flat hash table implementation. The underlying implementation is designed to avoid all allocations on insertion, removal, retrieval, and iteration. Allocations may still happen on insertion when the underlying storage needs to grow to accommodate newly added elements to the set.
