Enumeration

interface Enumeration<E : Any!>

java.util.Enumeration

Known Direct Subclasses

StringTokenizer

The string tokenizer class allows an application to break a string into tokens.

An object that implements the Enumeration interface generates a series of elements, one at a time. Successive calls to the nextElement method return successive elements of the series.

For example, to print all elements of a Vector<E> v:

for (Enumeration<E> e = v.elements(); e.hasMoreElements();)
        System.out.println(e.nextElement());

Methods are provided to enumerate through the elements of a vector, the keys of a hashtable, and the values in a hashtable. Enumerations are also used to specify the input streams to a SequenceInputStream.

Summary

Public methods
open MutableIterator<E>!	`asIterator()` Returns an `Iterator` that traverses the remaining elements covered by this enumeration.
abstract Boolean	`hasMoreElements()` Tests if this enumeration contains more elements.
abstract E	`nextElement()` Returns the next element of this enumeration if this enumeration object has at least one more element to provide.

Public methods

asIterator

Added in API level 33

open fun asIterator(): MutableIterator<E>!

Returns an Iterator that traverses the remaining elements covered by this enumeration. Traversal is undefined if any methods are called on this enumeration after the call to asIterator.

Return
`MutableIterator<E>!`	an Iterator representing the remaining elements of this Enumeration

hasMoreElements

Added in API level 1

abstract fun hasMoreElements(): Boolean

Tests if this enumeration contains more elements.

Return
`Boolean`	`true` if and only if this enumeration object contains at least one more element to provide; `false` otherwise.

nextElement

Added in API level 1

abstract fun nextElement(): E

Returns the next element of this enumeration if this enumeration object has at least one more element to provide.

Return
`E`	the next element of this enumeration.

Exceptions
`java.util.NoSuchElementException`	if no more elements exist.
