edu.rice.cs.plt.iter
Class ImmutableIterator<T>

java.lang.Object
  edu.rice.cs.plt.iter.ReadOnlyIterator<T>
      edu.rice.cs.plt.iter.ImmutableIterator<T>

All Implemented Interfaces:

Composite, java.util.Iterator<T>

public class ImmutableIterator<T>
extends ReadOnlyIterator<T>
implements Composite

Wraps an iterator in an immutable interface, preventing modifications to underlying data structures via ReadOnlyIterator.remove().

Constructor Summary

ImmutableIterator(java.util.Iterator<? extends T> i)

Method Summary

int	compositeHeight() Get the maximum path length from this node to a leaf.
int	compositeSize() Get the number of nodes in the tree rooted at this node.
boolean	hasNext()
static <T> ImmutableIterator<T>	make(java.util.Iterator<? extends T> i) Call the constructor (allows T to be inferred)
T	next()
