    public interface SequenceIterable

This interface is a simple subset of the Expression interface, that provides a single method to evaluate the result of an expression as a sequence

Method Summary
`SequenceIterator` `iterate(XPathContext context)` Return an iterator over the results of evaluating an expression

Method Detail

### iterate

    SequenceIterator iterate(XPathContext context)
                             throws XPathException

  Return an iterator over the results of evaluating an expression

  Parameters:
    `context` - the dynamic evaluation context
  Returns:
    an iterator over the items delivered by the expression
  Throws:
    `XPathException`
