- com.tangosol.coherence.config.xml.preprocessor.ExtendPreprocessor

All Implemented Interfaces:

DocumentElementPreprocessor.ElementPreprocessor
```
public class ExtendPreprocessor
extends Object
implements DocumentElementPreprocessor.ElementPreprocessor
```
An ExtendPreprocessor is an DocumentElementPreprocessor.ElementPreprocessor that will inject an "acceptor-config" XmlElement into a "proxy-scheme" XmlElement if one does not exist.

  - preprocess
```
public boolean preprocess(ProcessingContext context,
                          XmlElement element)
                   throws ConfigurationException
```
    Process an XmlElement, optionally mutating it (or it's children) if required.
    Note: An implementation of this interface should avoid attempting to traverse child XmlElements. If you wish to manually traverse or change the entire document, you should instead use a DocumentPreprocessor.
    
    Specified by:
    
    preprocess in interface DocumentElementPreprocessor.ElementPreprocessor
    
    Parameters:
    
    context - the ProcessingContext in which the pre-processing is occurring
    
    element - the XmlElement to preprocess
    
    Returns:
    
    true if the specified XmlElement should be re-preprocessed by this and other DocumentElementPreprocessor.ElementPreprocessors due to the XmlElement being modified, false otherwise.
    
    Throws:
    
    ConfigurationException - if during pre-processing of the XmlElement a configuration issue was discovered (or if pre-processing fails for some reason)
