Interface XMLResource

All Superinterfaces:
Resource
All Known Implementing Classes:
SimpleXMLResource, XMLResourceImpl

public interface XMLResource extends Resource
Provides access to XML resources stored in the database. An XMLResource can be accessed either as text XML or via the DOM or SAX APIs.

The default behavior for getContent and setContent is to work with XML data as text so these methods work on String content.

    Modifier and Type
    Method
    Description
    Returns the content of the Resource as a DOM Node.
    void
    Allows you to use a ContentHandler to parse the XML data from the database for use in an application.
    Returns the unique id for the parent document to this Resource or null if the Resource does not have a parent document.
    boolean
    Returns current setting of a SAX feature that will be used when this XMLResource is used to produce SAX events (through the getContentAsSAX() method)
    void
    Sets the content of the Resource using a DOM Node as the source.
    Sets the content of the Resource using a SAX ContentHandler.
    void
    setSAXFeature(String feature, boolean value)
    Sets a SAX feature that will be used when this XMLResource is used to produce SAX events (through the getContentAsSAX() method)

    • getDocumentId

      String getDocumentId() throws XMLDBException
      Returns the unique id for the parent document to this Resource or null if the Resource does not have a parent document. getDocumentId() is typically used with Resource instances retrieved using a query. It enables accessing the parent document of the Resource even if the Resource is a child node of the document. If the Resource was not obtained through a query then getId() and getDocumentId() will return the same id.
      Returns:
      the id for the parent document of this Resource or null if there is no parent document for this Resource.
      Throws:
      XMLDBException - with expected error codes.
      ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.
    • getContentAsDOM

      Node getContentAsDOM() throws XMLDBException
      Returns the content of the Resource as a DOM Node.
      Returns:
      The XML content as a DOM Node
      Throws:
      XMLDBException - with expected error codes.
      ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.
    • setContentAsDOM

      void setContentAsDOM(Node content) throws XMLDBException
      Sets the content of the Resource using a DOM Node as the source.
      Parameters:
      content - The new content value
      Throws:
      XMLDBException - with expected error codes.
      ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.
      ErrorCodes.INVALID_RESOURCE if the content value provided is null.
      ErrorCodes.WRONG_CONTENT_TYPE if the content provided in not a valid DOM Node.
    • getContentAsSAX

      void getContentAsSAX(ContentHandler handler) throws XMLDBException
      Allows you to use a ContentHandler to parse the XML data from the database for use in an application.
      Parameters:
      handler - the SAX ContentHandler to use to handle the Resource content.
      Throws:
      XMLDBException - with expected error codes.
      ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.
      ErrorCodes.INVALID_RESOURCE if the ContentHandler provided is null.
    • setContentAsSAX

      ContentHandler setContentAsSAX() throws XMLDBException
      Sets the content of the Resource using a SAX ContentHandler.
      Returns:
      a SAX ContentHandler that can be used to add content into the Resource.
      Throws:
      XMLDBException - with expected error codes.
      ErrorCodes.VENDOR_ERROR for any vendor specific errors that occur.
    • setSAXFeature

      void setSAXFeature(String feature, boolean value) throws SAXNotRecognizedException, SAXNotSupportedException
      Sets a SAX feature that will be used when this XMLResource is used to produce SAX events (through the getContentAsSAX() method)
      Parameters:
      feature - Feature name. Standard SAX feature names are documented at http://sax.sourceforge.net/.
      value - Set or unset feature
      Throws:
      SAXNotRecognizedException
      SAXNotSupportedException
    • getSAXFeature

      boolean getSAXFeature(String feature) throws SAXNotRecognizedException, SAXNotSupportedException
      Returns current setting of a SAX feature that will be used when this XMLResource is used to produce SAX events (through the getContentAsSAX() method)
      Parameters:
      feature - Feature name. Standard SAX feature names are documented at http://sax.sourceforge.net/.
      Returns:
      whether the feature is set
      Throws:
      SAXNotRecognizedException
      SAXNotSupportedException
