&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Interface summary ==&lt;br /&gt;
&lt;br /&gt;
=== General ===&lt;br /&gt;
&lt;br /&gt;
==== org.simantics.Simantics ====&lt;br /&gt;
&lt;br /&gt;
This static class can be used to obtain the active Session.&lt;br /&gt;
&lt;br /&gt;
==== org.simantics.db.Session ====&lt;br /&gt;
&lt;br /&gt;
The Session interface represents the connection into the semantic database. Implements e.g. RequestProcessor and serves various special interfaces via the getService-method.&lt;br /&gt;
&lt;br /&gt;
=== Reading and writing ===&lt;br /&gt;
&lt;br /&gt;
==== org.simantics.db.RequestProcessor ====&lt;br /&gt;
&lt;br /&gt;
RequestProcessor is a synchronous interface for making read queries and writes to the semantic database. Main implementations are Session, ReadGraph and WriteGraph&lt;br /&gt;
&lt;br /&gt;
==== org.simantics.db.Read ====&lt;br /&gt;
&lt;br /&gt;
The interface Read represents a query, which produces a single result. Main implementations are ResourceRead* and *naryRead.&lt;br /&gt;
&lt;br /&gt;
==== org.simantics.db.Write ====&lt;br /&gt;
&lt;br /&gt;
The interface Write represents a modification into the semantic database. Main implementation is WriteRequest.&lt;/div&gt;</summary>
