docs: This method will return the map that represents the passed in <code>type</code>.  The boolean flag
  </code>createIfNull</code> indicates that the map should be created or not if it's null. This
  class defines two maps defined by  <code>@see #ATTR_STYLE</code> and <code>ATTR_JAVASCRIPT</code>
  @param type         <code>integer</code> type indentifying the map to be created.
  @param createIfNull <code>boolean</code> flag indicating if the map should be created if it doesn't exist.
  @return The map or null
