| A JAXB Bean that works like a DOM.
This bean is bound to XML as a sequence of elements, where each
element[i] is from bridges[i] (which defines the tag name and the expected type)
and values[i] (which defines the actual value.)
This object allows you to treat multiple unrelated JAXB beans as a single tree.
This in turn allows you to marshal this tree in one marshal method invocation,
which is faster than multiple invocations of the marshal method. |
