java.lang.Object
- net.sf.saxon.evpull.ComplexContentProcessor

All Implemented Interfaces:

EventIterator, PullEvent
```
public class ComplexContentProcessor
extends java.lang.Object
implements EventIterator
```
The ComplexContentProcessor is an EventIterator that deals with the events occurring between a startElement and endElement (or startDocument and endDocument) according to the XSLT/XQuery rules for constructing complex content. This includes:
- Converting atomic values to text nodes (inserting space as a separator between adjacent nodes)
- Replacing nested document nodes by their children
- Merging adjacent text nodes and dropping zero-length text nodes
- Detecting mispositioned or duplicated attribute and namespace nodes
Note that if the content includes nodes such as element nodes, these will not be decomposed into a sequence of tree events, they will simply be returned as nodes.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`isFlatSequence()`	Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators
`PullEvent`	`next()`	Get the next event in the sequence.

```
public ComplexContentProcessor(Configuration config,
                               EventIterator base)
```
    Create the ComplexContentProcessor
    
    Parameters:
    
    config - the Saxon Configuration
    
    base - the EventIterator that delivers the content of the element or document node
- Method Detail
  - next
```
public PullEvent next()
               throws XPathException
```
    Get the next event in the sequence. This will never be an EventIterator.
    
    Specified by:
    
    next in interface EventIterator
    
    Returns:
    
    the next event, or null when the sequence is exhausted
    
    Throws:
    
    XPathException - if a dynamic evaluation error occurs
  - isFlatSequence
```
public boolean isFlatSequence()
```
    Determine whether the EventIterator returns a flat sequence of events, or whether it can return nested event iterators
    
    Specified by:
    
    isFlatSequence in interface EventIterator
    
    Returns:
    
    true if the next() method is guaranteed never to return an EventIterator
