Modifier and Type	Method and Description
`OrientConfigurableGraph.Settings`	`copy()`
`void`	`copyFrom(OrientConfigurableGraph.Settings settings)` copies only not null settings from the input settings object
`String`	`getConnectionStrategy()`
`int`	`getEdgeContainerEmbedded2TreeThreshold()` Returns the minimum number of edges for edge containers to transform the underlying structure from embedded to tree.
`int`	`getEdgeContainerTree2EmbeddedThreshold()` Returns the minimum number of edges for edge containers to transform the underlying structure from tree to embedded.
