      public OrientBaseGraph(ODatabaseDocumentInternal iDatabase, String iUserName, String iUserPassword, OrientConfigurableGraph.Settings iConfiguration)
      Constructs a new object using an existent database instance.
      Parameters:
      iDatabase - Underlying database object to attach

    • OrientBaseGraph

      public OrientBaseGraph(org.apache.commons.configuration.Configuration configuration)
      Builds a OrientGraph instance passing a configuration. Supported configuration settings are:
      Name Description Default value
      blueprints.orientdb.url Database URL -
      blueprints.orientdb.username User name admin
      blueprints.orientdb.password User password admin
      blueprints.orientdb.saveOriginalIds Saves the original element IDs by using the property origId. This could be useful on import of graph to preserve original ids false
      blueprints.orientdb.keepInMemoryReferences Avoid to keep records in memory but only RIDs false
      blueprints.orientdb.useCustomClassesForEdges Use Edge's label as OrientDB class. If doesn't exist create it under the hood true
      blueprints.orientdb.useCustomClassesForVertex Use Vertex's label as OrientDB class. If doesn't exist create it under the hood true
      blueprints.orientdb.useVertexFieldsForEdgeLabels Store the edge relationships in vertex by using the Edge's class. This allow to use multiple fields and make faster traversal by edge's label (class) true
      blueprints.orientdb.lightweightEdges Uses lightweight edges. This avoid to create a physical document per edge. Documents are created only when they have properties true
      blueprints.orientdb.autoScaleEdgeType Set auto scale of edge type. True means one edge is managed as LINK, 2 or more are managed with a LINKBAG false
      blueprints.orientdb.edgeContainerEmbedded2TreeThreshold Changes the minimum number of edges for edge containers to transform the underlying structure from embedded to tree. Use -1 to disable transformation -1
      blueprints.orientdb.edgeContainerTree2EmbeddedThreshold Changes the minimum number of edges for edge containers to transform the underlying structure from tree to embedded. Use -1 to disable transformation -1
