Interface RubyContract.Enumerator<E,N extends RubyContract.Enumerator<?,?,?>,Z extends RubyContract.Enumerable<?,?,?>>

Type Parameters:

E - the type of the elements

N - the type of what kind of RubyContract.Enumerator should be used

Z - the type to define if some methods are lazy or eager loading

All Superinterfaces:

java.lang.Iterable<E>, java.util.Iterator<E>, RubyContract.Enumerable<E,N,Z>

All Known Subinterfaces:

Ruby.Enumerator<E>, Ruby.LazyEnumerator<E>

All Known Implementing Classes:

RubyEnumerator, RubyLazyEnumerator

Enclosing class:

RubyContract

static interface RubyContract.Enumerator<E,N extends RubyContract.Enumerator<?,?,?>,Z extends RubyContract.Enumerable<?,?,?>>
extends RubyContract.Enumerable<E,N,Z>, java.lang.Iterable<E>, java.util.Iterator<E>

RubyContract.Enumerator defines all methods of a Ruby Enumerator should have.
