Class StreamReaderBufferProcessor

  • All Implemented Interfaces:
    javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader, org.jvnet.staxex.XMLStreamReaderEx
    public class StreamReaderBufferProcessor
extends AbstractProcessor
implements org.jvnet.staxex.XMLStreamReaderEx
    A processor of a XMLStreamBuffer that reads the XML infoset as XMLStreamReader.

    Because of XMLStreamReader design, this processor always produce a full document infoset, even if the buffer just contains a fragment.

    When XMLStreamBuffer contains a multiple tree (AKA "forest"), XMLStreamReader will behave as if there are multiple root elements (so you'll see XMLStreamConstants.START_ELEMENT event where you'd normally expect XMLStreamConstants.END_DOCUMENT.)

    • Field Detail

      • _depth

        protected int _depth
        The element depth that we are in. Used to determine when we are done with a tree.

      • _namespaceAIIsPrefix

        protected java.lang.String[] _namespaceAIIsPrefix
        Namespace prefixes. Can be empty but not null.

      • _namespaceAIIsNamespaceName

        protected java.lang.String[] _namespaceAIIsNamespaceName

      • _namespaceAIIsEnd

        protected int _namespaceAIIsEnd

      • _eventType

        protected int _eventType

      • _attributeCache

        protected AttributesHolder _attributeCache
        Holder of the attributes. Be careful that this follows the SAX convention of using "" instead of null.

      • _charSequence

        protected java.lang.CharSequence _charSequence

      • _characters

        protected char[] _characters

      • _textOffset

        protected int _textOffset

      • _textLen

        protected int _textLen

      • _piTarget

        protected java.lang.String _piTarget

      • _piData

        protected java.lang.String _piData

      • PARSING

        private static final int PARSING
        The parser is in the middle of parsing a document, with no end in sight.
        See Also:
        Constant Field Values

      • PENDING_END_DOCUMENT

        private static final int PENDING_END_DOCUMENT
        The parser has already reported the XMLStreamConstants.END_ELEMENT, and we are parsing a fragment. We'll report XMLStreamConstants.END_DOCUMENT next and be done.
        See Also:
        Constant Field Values

      • COMPLETED

        private static final int COMPLETED
        The parser has reported the XMLStreamConstants.END_DOCUMENT event, so we are really done parsing.
        See Also:
        Constant Field Values

      • _completionState

        private int _completionState
        True if processing is complete.

    • Method Detail

      • setXMLStreamBuffer

        public void setXMLStreamBuffer​(XMLStreamBuffer buffer)
                        throws javax.xml.stream.XMLStreamException
        Throws:
        javax.xml.stream.XMLStreamException

      • nextTagAndMark

        public XMLStreamBuffer nextTagAndMark()
                               throws javax.xml.stream.XMLStreamException
        Does nextTag() and if the parser moved to a new start tag, returns a XMLStreamBufferMark that captures the infoset starting from the newly discovered element.

        (Ideally we should have a method that works against the current position, but the way the data structure is read makes this somewhat difficult.) This creates a new XMLStreamBufferMark that shares the underlying data storage, thus it's fairly efficient.
