Classes in oracle.pg.rdbms used by oracle.pg.rdbms

Class and Description
DataChange
DataChange.ChangeAction
EdgeChange This class captures an action of change made to a particular Edge instance.
Oracle This class manages the RDBMS JDBC connection to an Oracle semantic store.
OracleChangeTracker An interface to track the changes executed over a Property Graph
OracleCommonIteratorImpl This class implements a common Iterator interface for iterating through elements as well as changes.
OracleEdge This class implements the Blueprints Edge and Element interface by using an Oracle backend.
OracleElementIteratorImpl This class implements the Iterator interface for elements (vertices and edges).
OraclePgqlColumnDescriptor Deprecated. As of version 20c, replaced by PgqlColumnDescriptor Describes the metadata for a logical column in a PGQL query result.
OraclePgqlColumnDescriptor.Type Deprecated. Types of logical return columns
OraclePgqlPreparedStatement Deprecated. As of version 20c, replaced by PgqlPreparedStatement This object represents a pre-compiled PGQL statement. A PGQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times. Bind variables can be used to efficient execute parameterized queries. A typical usage is shown below. Oracle oracle = new Oracle(jdbcUrl,user,password); OraclePropertyGraph graph = OraclePropertyGraph.getInstance(oracle,graphName); String pgqlString = "SELECT n.name WHERE (n WITH id()=?)"; OraclePgqlPreparedStatement opps = OraclePgqlExecutionFactory.prepareStatement(graph, pgqlString); opps.setInt(1, 4); OraclePgqlResultSet oprs = opps.executeQuery("USE_GT_TAB=T"); OraclePgqlResultSetMetaData rsmd = oprs.getMetaData(); Iterator<OraclePgqlResult> itr = oprs.getResults().iterator(); while(itr.hasNext()) { OraclePgqlResult opr = itr.next(); for (int i = 1; i <= rsmd.getColumnCount(); i++) { OraclePgqlColumnDescriptor.Type t = opr.getColumnType(i); switch (t) { case VERTEX: // process vertex break; case EDGE: // process edge break; case VALUE: // process value break; } } } oprs.close(); opps.close();
OraclePgqlResult Deprecated. As of version 20c, replaced by PgqlResultSet Holds a single row in a PGQL query result.
OraclePgqlResultElement Deprecated. As of version 20c, replaced by PgqlResultElement Represents a single element in a PGQL query result row.
OraclePgqlResultSet Deprecated. As of version 20c, replaced by PgqlResultSet This interface provides a ResultSet for a PGQL query execution. It uses an iterator-based approach for consuming the query result.
OraclePgqlResultSetMetaData Deprecated. As of version 20c, replaced by oracle.pg.rdbms.pgql.PgqlResultSetMetaData Describes column meta data for a PGQL query result.
OraclePgqlSqlTrans Deprecated. As of version 20c, replaced by PgqlSqlQueryTrans Holds the SQL translation of a PGQL query.
OraclePgqlStatement Deprecated. As of version 20c, replaced by PgqlStatement This interface is used to execute a static PGQL query. A typical usage is shown below. Oracle oracle = new Oracle(jdbcUrl,user,password); OraclePropertyGraph graph = OraclePropertyGraph.getInstance(oracle,graphName); OraclePgqlStatement ops = OraclePgqlExecutionFactory.createStatement(graph); OraclePgqlResultSet oprs = ops.executeQuery(pgqlString, "USE_GT_TAB=T"); OraclePgqlResultSetMetaData rsmd = oprs.getMetaData(); Iterator<OraclePgqlResult> itr = oprs.getResults().iterator(); while(itr.hasNext()) { OraclePgqlResult opr = itr.next(); for (int i = 1; i <= rsmd.getColumnCount(); i++) { OraclePgqlColumnDescriptor.Type t = opr.getColumnType(i); switch (t) { case VERTEX: // process vertex break; case EDGE: // process edge break; case VALUE: // process value break; } } } oprs.close(); ops.close();
OraclePropertyGraph This class implements the Blueprints Graph interface by using an Oracle backend.
OraclePropertyGraphAnalytics This interface defines analytical functions that are supported by OraclePropertyGraph
OraclePropertyGraphConfigurationConstants
OraclePropertyGraphDataLoader This class implements the logic to load a property graph (in Oracle-defined flat files format) into supported backend database.
OraclePropertyGraphException This class extends the Java RuntimeException.
OraclePropertyGraphFeatures Oracle's extension of Features class
OracleVertex This class implements the Blueprints Vertex and Element interface by using an Oracle backend.
OrderedVertexIdIteratorImpl This class implements the Iterator interface for vertices ordered by ID
Parameters An Oracle Utility to get additional property graph configuration settings taken from JVM settings.
PGUtils.RDFPredicate This class defines how to map RDF predicates to property graph attributes/keys
SQLAnalyticsGraph
SQLAnalyticsGraph.Sort This enumeration denotes the sorting order for function getTopK
VertexChange This class captures an action of change made to a particular Vertex instance.
