public UnmodifiableIterator(java.util.Iterator<E> iter)
Constructor for UnmodifiableIterator class.

Parameters:
iter - The Iterator that this object is to be based on.
Method Detail

hasNext

public boolean hasNext()

Specified by:
hasNext in interface java.util.Iterator<E>
Returns:

next in interface java.util.Iterator<E>
Returns:
The next element in the iteration.

remove

public void remove()
Unsupported method. Throws an UnsupportedOperationException if called.
