Struct blackboxmc_java::util::JavaListIterator

#[repr(C)]
pub struct JavaListIterator<'mc>(_, _);

An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator’s current position in the list. A ListIterator has no current element; its cursor position always lies between the element that would be returned by a call to previous() and the element that would be returned by a call to next(). An iterator for a list of length n has n+1 possible cursor positions, as illustrated by the carets (^) below:

Element(0) Element(1) Element(2) ... Element(n-1)
cursor positions:^^^^^

Note that the remove() and set(Object) methods are not defined in terms of the cursor position; they are defined to operate on the last element returned by a call to next() or previous().

This interface is a member of the Java Collections Framework.

This is a representation of an abstract class.
