All Implemented Interfaces:

PullProvider
```
public class PullPushTee
extends PullFilter
```
PullPushTee is a pass-through filter class that links one PullProvider to another PullProvider in a pipeline, copying all events that are read into a push pipeline, supplied in the form of a Receiver.
This class can be used to insert a schema validator into a pull pipeline, since Saxon's schema validation is push-based. It could also be used to insert a serializer into the pipeline, allowing the XML document being "pulled" to be displayed for diagnostic purposes.

  - PullPushTee
```
public PullPushTee(PullProvider base,
                   Receiver branch)
```
    Create a PullPushTee
    
    Parameters:
    
    base - the PullProvider to which requests are to be passed
    
    branch - the Receiver to which all events are to be copied, as "push" events. This Receiver must already be open before use
- Method Detail
  - getReceiver
```
public Receiver getReceiver()
```
    Get the Receiver to which events are being tee'd.
    
    Returns:
    
    the Receiver
  - next
```
public PullProvider.Event next()
                        throws XPathException
```
    Get the next event. This implementation gets the next event from the underlying PullProvider, copies it to the branch Receiver, and then returns the event to the caller.
    
    Specified by:
    
    next in interface PullProvider
    
    Overrides:
    
    next in class PullFilter
    
    Returns:
    
    an integer code indicating the type of event. The code PullProvider.Event.END_OF_INPUT is returned at the end of the sequence.
    
    Throws:
    
    XPathException - if a dynamic error occurs
