Class StandardObjectConverter

  • All Implemented Interfaces:
    ObjectConverter
    public class StandardObjectConverter
extends java.lang.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

        convertToItem in interface ObjectConverter
        Parameters:
