Class StandardObjectConverter

java.lang.Object
com.saxonica.xqj.StandardObjectConverter
All Implemented Interfaces:
ObjectConverter
public class StandardObjectConverter extends Object implements ObjectConverter
This class provides all the conversion methods used to convert data between XDM values and Java values in the XQJ API. At one time the XQJ specification defined such a class, and it has been retained in the Saxon implementation.

This handler implements the mappings defined in the XQJ specification. In addition, it defines the following mappings, which are applied after those defined in XQJ:

For fromObject:

  • If the supplied object is an instance of javax.xml.transform.Source, a document node is constructed from the source and the resulting node is returned as the Item
  • If the supplied object is an instance of javax.xml.stream.XMLStreamReader, a document node is constructed from the XMLStreamReader and the resulting node is returned as the Item
  • If the supplied object is

      Returns:
      the Java object that results from the conversion
      Throws:

      Returns:
      the corresponding Item
      Throws:

    • convertToItem

      public Item convertToItem(Object value, XQItemType type) throws XQException
