Examples with XMLIndexReader com.ibm.jvm.j9.dump.indexsupport.XMLIndexReader used on opensource projects

Example 1 with XMLIndexReader

use of com.ibm.jvm.j9.dump.indexsupport.XMLIndexReader in project openj9 by eclipse.

the class DTFJImageFactory method getImage.

private ReleasingImage getImage(File imageFile, InputStream metadata, IFileLocationResolver resolver) throws IOException {
    ClosingFileReader reader = new ClosingFileReader(imageFile);
    ICoreFileReader core = DumpFactory.createDumpForCore(reader);
    XMLIndexReader indexData = new XMLIndexReader();
    // CMVC 154851 : pass the metadata stream through the new XML cleanup class
    XMLInputStream in = new XMLInputStream(metadata);
    ReleasingImage image = indexData.parseIndexWithDump(in, core, reader, resolver);
    image.addReleasable(in);
    image.addReleasable(reader);
    image.addReleasable(core);
    if (resolver instanceof ResourceReleaser) {
        image.addReleasable((ResourceReleaser) resolver);
    }
    return image;
}

Example 2 with XMLIndexReader

use of com.ibm.jvm.j9.dump.indexsupport.XMLIndexReader in project openj9 by eclipse.

the class DTFJImageFactory method getImage.

		 * Legacy core readers implement the ImageInputStream interface, but are backed by an implementation which
		 * is based around reading bytes directly from the stream without honouring the ByteOrder setting of the stream.
		 * This has the consequence that the readers expect all streams passes to them to be in BIG_ENDIAN order and
		 * then internally provide wrapper classes when LITTLE_ENDIAN is required. This is why the stream being
		 * passed has it's byte order fixed to BIG_ENDIAN.
