Example 1 with NamespaceNode

use of org.sirix.node.NamespaceNode in project sirix by sirixdb.

the class XdmNodeWriterTrxImpl method insertNamespace.

Example 2 with NamespaceNode

use of org.sirix.node.NamespaceNode in project sirix by sirixdb.

the class NodeFactoryImpl method createNamespaceNode.

@Override

    final long revision = mPageWriteTrx.getRevisionNumber();
