      public interface XMLizable

  An interface to be implemented by UIMA classes that can be written to and parsed from XML. Classes must implement this interface in order for the UIMA `XMLParser` to generate them from XML documents. XMLizable classes also must define a zero-argument constructor. When constructing an object, the `XMLParser` will first create it using the zero-argument constructor and then call `buildFromXMLElement(Element,XMLParser)`.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `buildFromXMLElement(Element aElement, XMLParser aParser)` Initializes this object from its XML DOM representation.
    `void` | `buildFromXMLElement(Element aElement, XMLParser aParser, XMLParser.ParsingOptions aOptions)` Initializes this object from its XML DOM representation.
    `void` | `toXML(ContentHandler aContentHandler)` Writes this object's XML representation by making calls on a SAX `ContentHandler`.
    `void` | `toXML(ContentHandler aContentHandler, boolean aWriteDefaultNamespaceAttribute)` Writes this object's XML representation by making calls on a SAX `ContentHandler`.
    `void` | `toXML(OutputStream aOutputStream)` Writes this object's XML representation as a string in UTF-8 encoding.
    `void` | `toXML(Writer aWriter)` Writes this object's XML representation as a string.

    - #### toXML

          void toXML(Writer aWriter)
              throws SAXException,
                     IOException

      Writes this object's XML representation as a string. Note that if you want to write the XML to a file or to a byte stream, it is highly recommended that you use `toXML(OutputStream)` instead, as it ensures that output is written in UTF-8 encoding, which is the default encoding that should be used for XML files.

      The XML String that is produced will have a header `<?xml version="1.0" encoding="UTF-8"?>`. Therefore you should not write this string out in any encoding other than UTF-8 (for example do not use the default platform encoding), or you will produce output that will not be able to be parsed.

      Parameters:
        `aWriter` - a Writer to which the XML string will be written
      Throws:
        `IOException` - if an I/O failure occurs
        `SAXException` - passthru

    - #### toXML

          void toXML(OutputStream aOutputStream)
              throws SAXException,
                     IOException

      Writes this object's XML representation as a string in UTF-8 encoding.
      Parameters:
        `aOutputStream` - an OutputStream to which the XML string will be written, in UTF-8 encoding.
      Throws:
        `IOException` - if an I/O failure occurs
        `SAXException` - pass thru

    - #### toXML

          void toXML(ContentHandler aContentHandler)
              throws SAXException

      Writes this object's XML representation by making calls on a SAX `ContentHandler`. This method just calls `toXML(aContentHandler,false)`, so subclasses should override that version of this method, not this one.
      Parameters:
        `aContentHandler` - the content handler to which this object will write events that describe its XML representation.
      Throws:
        `SAXException` - pass thru

    - #### toXML

          void toXML(ContentHandler aContentHandler,
                     boolean aWriteDefaultNamespaceAttribute)
              throws SAXException

      Writes this object's XML representation by making calls on a SAX `ContentHandler`.
      Parameters:
        `aContentHandler` - the content handler to which this object will write events that describe its XML representation.
        `aWriteDefaultNamespaceAttribute` - whether the namespace of this element should be written as the default namespace. This should be done only for the root element, and it defaults to false.
      Throws:
        `SAXException` - pass thru

    - #### buildFromXMLElement

          void buildFromXMLElement(Element aElement,
                                   XMLParser aParser)
                            throws InvalidXMLException

      Initializes this object from its XML DOM representation. This method is typically called from the `XMLParser`.
      Parameters:
        `aElement` - the XML element that represents this object.
        `aParser` - a reference to the UIMA `XMLParser`. The `XMLParser.buildObject(Element)` method can be used to construct sub-objects.
      Throws:
        `InvalidXMLException` - if the input XML element does not specify a valid object

    - #### buildFromXMLElement

          void buildFromXMLElement(Element aElement,
                                   XMLParser aParser,
                                   XMLParser.ParsingOptions aOptions)
                            throws InvalidXMLException

      Initializes this object from its XML DOM representation. This method is typically called from the `XMLParser`.
      Parameters:
        `aElement` - the XML element that represents this object.
        `aParser` - a reference to the UIMA `XMLParser`. The `XMLParser.buildObject(Element)` method can be used to construct sub-objects.
        `aOptions` - option settings
      Throws:
        `InvalidXMLException` - if the input XML element does not specify a valid object
