Class XmlSaxDataContextFactory

java.lang.Object

org.apache.metamodel.xml.XmlSaxDataContextFactory

All Implemented Interfaces:

org.apache.metamodel.factory.DataContextFactory

public class XmlSaxDataContextFactory
extends Object
implements org.apache.metamodel.factory.DataContextFactory

A DataContextFactory for XML files where a "table-defs" or "xml-sax-table-defs" element has been configured and represents the tables and their XPaths as defined by XmlSaxDataContext. If "table-defs" is specified, it will first be interpreted as a SimpleTableDef which is then mapped to a XmlSaxTableDef. Alternatively, if "xml-sax-table-defs" is specified, it may either be a List, like this (JSON representation of lists and maps):

 [
   {
     "row-x-path": "/path/to/entity1"
     "value-x-paths": [
       "/path/to/entity1/var1",
       "/path/to/entity1/var2"
     ]
   },
   {
     "row-x-path": "/path/to/model2"
     "value-x-paths": [
       "/path/to/model2/field3",
       "/path/to/model2/field4"
     ]
   }
 ]
 

Or a key/value map, like this:

   {
     "/path/to/entity1": [
       "/path/to/entity1/var1",
       "/path/to/entity1/var2"
     ],
     "/path/to/model2": [
       "/path/to/model2/field3",
       "/path/to/model2/field4"
     ]
   }
