public final class FastInfosetStreamWriterOutput extends XMLStreamWriterOutput
XmlOutputforStAXDocumentSerializer.This class is responsible for managing the indexing of elements, attributes and local names that are known to JAXB by way of the JAXBContext (generated from JAXB beans or schema). The pre-encoded UTF-8 representations of known local names are also utilized.
The lookup of elements, attributes and local names with respect to a context is very efficient. It relies on an incrementing base line so that look up is performed in O(1) time and only uses static memory. When the base line reaches a point where integer overflow will occur the arrays and base line are reset (such an event is rare and will have little impact on performance).
A weak map of JAXB contexts to optimized tables for attributes, elements and local names is utilized and stored on the LowLevel StAX serializer. Thus, optimized serializing can work other multiple serializing of JAXB beans using the same LowLevel StAX serializer instance. This approach works best when JAXB contexts are only created once per schema or JAXB beans (which is the recommended practice as the creation JAXB contexts are expensive, they are thread safe and can be reused).
