Example 1 with GraphMLWriter

use of com.tinkerpop.blueprints.util.io.graphml.GraphMLWriter in project orientdb by orientechnologies.

the class OGremlinConsole method exportDatabase.

@Override
@ConsoleCommand(description = "Export a database", splitInWords = false, onlineHelp = "Console-Command-Export")
public void exportDatabase(@ConsoleParameter(name = "options", description = "Export options") String iText) throws IOException {
    checkForDatabase();
    final List<String> items = OStringSerializerHelper.smartSplit(iText, ' ');
    final String fileName = items.size() <= 1 || items.get(1).charAt(0) == '-' ? null : items.get(1);
    if (fileName != null && (fileName.endsWith(".graphml") || fileName.endsWith(".xml"))) {
        message("\nExporting database in GRAPHML format to " + iText + "...");
        try {
            final OrientGraph g = (OrientGraph) OrientGraphFactory.getTxGraphImplFactory().getGraph(currentDatabase);
            g.setUseLog(false);
            g.setWarnOnForceClosingTx(false);
            // CREATE THE EXPORT FILE IF NOT EXIST YET
            final File f = new File(fileName);
            if (f.getParentFile() != null) {
                f.getParentFile().mkdirs();
            }
            f.createNewFile();
            new GraphMLWriter(g).outputGraph(fileName);
        } catch (ODatabaseImportException e) {
            printError(e);
        }
    } else
        // BASE EXPORT
        super.exportDatabase(iText);
}

Example 2 with GraphMLWriter

use of com.tinkerpop.blueprints.util.io.graphml.GraphMLWriter in project hale by halestudio.
