Purpose

Holds a com.sleepycat.dbxml.XmlResults.

This aspect is useful for scripting languages to iterate over a result set. This aspect must be treated as immutable. Once its values have been read it is strongly adviced that the delete() method is called on the XmlResults object - this will clean up any native resources held in the underlying native DBXML database.

public class DBXMLResultAspect implements IURAspect
{
    private XmlResults mResults;

    public DBXMLResultAspect(XmlResults aResults)
    {   mResults=aResults;
    }
    
    public XmlResults getXmlResultsReadOnly()
    {   return mResults;
    }
    
    public boolean isEmpty() throws Exception
    {   return mResults.size()==0;      
    }
    
    public boolean hasXmlDocument() throws Exception
    {   if (mResults.size()!=1) return false;
        XmlValue val=mResults.peek();
        try
        {   val.asDocument();
            return true;
        }
        catch(Exception e)
        {   return false;           
        }
    }
