Class WrappedTextNodeStreamReader

  • All Implemented Interfaces:
    XMLStreamConstants, XMLStreamReader
    public class WrappedTextNodeStreamReader
extends Object
implements XMLStreamReader
    XMLStreamReader implementation that represents a text node wrapped inside an element. The text data is provided by a Reader.

    It will produce the following sequence of XML events:

    • START_DOCUMENT
    • START_ELEMENT
    • (CHARACTER)*
    • END_ELEMENT
    • END_DOCMENT
    The class is implemented as a simple state machine, where the state is identified by the current event type. The initial state is START_DOCUMENT and the following transitions are triggered by next():
    • START_DOCUMENT → START_ELEMENT
    • START_ELEMENT → END_ELEMENT (if character stream is empty)
    • START_ELEMENT → CHARACTERS (if character stream is not empty)
    • CHARACTERS → CHARACTERS (if data available in stream)
    • CHARACTERS → END_ELEMENT (if end of stream reached)
    • END_ELEMENT → END_DOCUMENT
    Additionally, getElementText() triggers the following transition:
    • START_ELEMENT → END_ELEMENT
    Note that since multiple consecutive CHARACTERS events may be returned, this "parser" is not coalescing.
