Method Detail

iterable

public static final <T> java.lang.Iterable<T> iterable(java.util.Enumeration<T> enumeration)

Allows using of Enumeration with the for-each statement. The implementation is not using any heap space and such is able to serve virtually endless Enumerations, while Collections.list(java.util.Enumeration<T>) is limited by available RAM. As a result, this implementation is much faster than Collections.list.

Parameters:

enumeration - The original enumeration.

Returns:

An Iterable directly calling the original Enumeration.
