Class Summary
`class` | ArrayBuffer [A]`extends` Mutable[A]`with` Buffer[A]`with` ResizableArray[A] An implementation of the `Buffer` class using an array to represent the assembled sequence internally.
`class` | BitSet (initSize : Int)`extends` BitSet `with` Set[Int] The class `BitSet` implements mutable, resizable Bit sets
`trait` | Buffer [A]`extends` Seq[A]`with` Scriptable[Message[(Location, A)]]`with` CloneableCollection Buffers are used to create sequences of elements incrementally by appending, prepending, or inserting new elements. It is also possible to access and modify elements in a random access fashion via the index of the element in the current sequence.
`trait` | BufferProxy [A]`extends` Buffer[A]`with` Proxy This is a simple proxy class for `scala.collection.mutable.Buffer`. It is most useful for assembling customized set abstractions dynamically using object composition and forwarding.
`trait` | CloneableCollection `extends` AnyRef The J2ME version of the library defined this trait with a clone method to substitute for the lack of Object.clone there
`final class` | DefaultEntry [A, B](`val` key : A, `val` value : B)`extends` HashEntry[A, DefaultEntry[A, B]]
`trait` | DefaultMapModel [A, B]`extends` Map[A, B] This class is used internally. It implements the mutable `Map` class in terms of three functions: `findEntry`, `addEntry`, and `entries`.
`abstract class` | DoubleLinkedList [A, This <: DoubleLinkedList[A, This] >: Null]`extends` SingleLinkedList[A, This] This extensible class may be used as a basis for implementing double linked lists. Type variable `A` refers to the element type of the list, type variable `This` is used to model self types of linked lists.
`trait` | FlatHashTable [A]`extends` AnyRef
`trait` | HashEntry [A, E]`extends` AnyRef
`class` | HashMap [A, B]`extends` HashTable[A]`with` DefaultMapModel[A, B]
`class` | HashSet [A]`extends` Set[A]`with` FlatHashTable[A]
`trait` | HashTable [A]`extends` AnyRef This class can be used to construct data structures that are based on hashtables. Class `HashTable[A]` implements a hashtable that maps keys of type `A` to values of the fully abstract member type `Entry`. Classes that make use of `HashTable` have to provide an implementation for `Entry` There are mainly two parameters that affect the performance of a hashtable: the initial size and the load factor. The size refers to the number of buckets in the hashtable, and the load factor is a measure of how full the hashtable is allowed to get before its size is automatically doubled. Both parameters may be changed by overriding the corresponding values in class `HashTable`.
