    - *

    • - *
  • skippedEntity
    • - *
      - * Also the following StAX events are not mapped: - *
        - *

      • COMMENT

      - * StAX ATTRIBUTE events are ignored but the equivalent attributes (derived from - * the START_ELEMENT event) are supplied in the SAX startElement event's - * Attributes parameter. If the adaptor is configured to pass namespace prefixes - * then namespace information will also be included in the Attributes; StAX - * NAMESPACE events are ignored.

      Another issue is namespace processing. If - * the reader is positioned at a sub-node, we cannot capture all the in-scope - * namespace bindings. Therefore we cannot re-create a proper SAX event stream - * from a StAX parser.

      For example

      <a:root xmlns:a="foo" - * xmlns:b="bar"><b:sub>a:foo</b:sub></a:root>

      And if - * you are handed a parser at <b:sub>, then your SAX events should look - * like:

      <b:sub xmlns:a="foo" xmlns:b="bar">a:foo</b:sub>

      - * not:

      <b:sub>a:foo</b:sub>

The approach - * here is simple When the pull parser needs to generate events for a particular - * name-value(s) pair it always hands over (delegates) the task to another pull - * parser which knows how to deal with it The common types of name value pairs - * we'll come across are - *

        - *
      • String name/QName name - String value - *
      • String name/QName name - String[] value - *
      • QName name/String name - XMLStreamReader value - *
      • QName name/String name - XMLStreamable value - *
      • QName name/String name - Java bean - *
      • QName name/String name - Datahandler - * - *
      - *

      As for the attributes, these are the possible combinations in the array - *

        - *
      • String name/QName name - String value - *
      - * Note that certain array methods have been deliberately removed to avoid - * complications. The generated code will take the trouble to lay the elements - * of the array in the correct order

      Hence there will be a parser impl - * that knows how to handle these types, and this parent parser will always - * delegate these tasks to the child pullparasers in effect this is one huge - * state machine that has only a few states and delegates things down to the - * child parsers whenever possible
