public static class ProjectHelper2.AntHandler

    • onStartElement

      public void onStartElement​(java.lang.String uri, java.lang.String tag, java.lang.String qname, org.xml.sax.Attributes attrs, AntXMLContext context) throws org.xml.sax.SAXParseException
      Handles the start of an element. This base implementation does nothing.
      Parameters:
      uri - the namespace URI for the tag
      tag - The name of the element being started. Will not be null.
      qname - The qualified name of the element.
      attrs - Attributes of the element being started. Will not be null.
      context - The context that this element is in.
      Throws:
      org.xml.sax.SAXParseException - if this method is not overridden, or in case of error in an overridden version

    • onStartChild

      public ProjectHelper2.AntHandler onStartChild​(java.lang.String uri, java.lang.String tag, java.lang.String qname, org.xml.sax.Attributes attrs, AntXMLContext context) throws org.xml.sax.SAXParseException
      Handles the start of an element. This base implementation just throws an exception - you must override this method if you expect child elements.
      Parameters:
      uri - The namespace uri for this element.
      tag - The name of the element being started. Will not be null.
      qname - The qualified name for this element.
      attrs - Attributes of the element being started. Will not be null.
      context - The current context.
      Returns:
      a handler (in the derived classes)
      Throws:
      org.xml.sax.SAXParseException - if this method is not overridden, or in case of error in an overridden version

    • onEndChild

      public void onEndChild​(java.lang.String uri, java.lang.String tag, java.lang.String qname, AntXMLContext context) throws org.xml.sax.SAXParseException
      Handle the end of a element.
      Parameters:
      uri - the namespace uri of the element
      tag - the tag of the element
      qname - the qualified name of the element
      context - the current context
      Throws:
      org.xml.sax.SAXParseException - if an error occurs

    • onEndElement

      public void onEndElement​(java.lang.String uri, java.lang.String tag, AntXMLContext context)
      This method is called when this element and all elements nested into it have been handled. I.e., this happens at the </end_tag_of_the_element>.
      Parameters:
      uri - the namespace uri for this element
      tag - the element name
      context - the current context

    • characters

      public void characters​(char[] buf, int start, int count, AntXMLContext context) throws org.xml.sax.SAXParseException
      Handles text within an element. This base implementation just throws an exception, you must override it if you expect content.
      Parameters:
      buf - A character array of the text within the element. Will not be null.
      start - The start element in the array.
      count - The number of characters to read from the array.
