    java.lang.Object
      net.sf.saxon.expr.MonoIterator

All Implemented Interfaces:

    public class MonoIterator

extends Object
implements Iterator

An iterator over a single object (typically a sub-expression of an expression)

`Object` | `next()` Returns the next element in the iteration.
`void` | `remove()` Removes from the underlying collection the last element returned by the iterator (optional operation).

Constructor Detail

### MonoIterator

    public MonoIterator(Object thing)

Method Detail

### hasNext

    public boolean hasNext()

  Returns `true` if the iteration has more elements. (In other words, returns `true` if `next` would return an element rather than throwing an exception.)

  Specified by:
    `hasNext` in interface `Iterator`
  Returns:
    `true` if the iterator has more elements.

### next

    public Object next()

  Returns the next element in the iteration.

  Specified by:
    `next` in interface `Iterator`
  Returns:
    the next element in the iteration.
  Throws:
    `NoSuchElementException` - iteration has no more elements.

### remove

    public void remove()

  Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to `next`. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

  Specified by:
    `remove` in interface `Iterator`
  Throws:
    `UnsupportedOperationException` - if the `remove` operation is not supported by this Iterator (which is the case for this iterator).
