Example 79 with XMLStreamReader

use of javax.xml.stream.XMLStreamReader in project webservices-axiom by apache.

the class TestBlobOMDataSource method runTest.

@Override

    reader.next();
    assertTrue("OMSourcedElement is expanded.  This is unexpected", !child.isExpanded());
    // Likewise, a BlobOMDataSource does not consume the backing object when

Example 80 with XMLStreamReader

use of javax.xml.stream.XMLStreamReader in project webservices-axiom by apache.

the class BEAInputFactoryWrapper method createXMLStreamReader.

@Override
public XMLStreamReader createXMLStreamReader(String systemId, InputStream stream) throws XMLStreamException {
    // The getEncoding() method of the stream reader produced by the reference implementation
    // doesn't return complete information about the effective encoding. To work around this,
    // we need to implement the detection algorithm described in Appendix F.1 of the
    // XML 1.0 specifications (Fifth Edition). Note that the encoding determined here may be
    // overridden by the XML encoding declaration, if present in the XML document. This
    // information is already available from the stream reader, so that we don't need to
    // reimplement this part.
    // TODO: this needs some more unit testing!
    EncodingDetectionHelper helper = new EncodingDetectionHelper(stream);
    stream = helper.getInputStream();
    String encoding = helper.detectEncoding();
    XMLStreamReader reader;
    if (systemId == null) {

    } else {
        reader = super.createXMLStreamReader(systemId, stream);
