getProperties

public Map<String,Object> getProperties(CatalogName catalog,
                                              String catalogNameForDiagnostics,
                                              Iterable<Property> properties,
                                              Session session,
                                              PlannerContext plannerContext,
                                              AccessControl accessControl,
                                              Map<NodeRef<Parameter>,Expression> parameters)

Evaluate properties. The returned Map<String, Object> contains a supported property iff its value is (implicitly or explictly) set to a non-null value. Thus,

• If a property does not appear in the result, then its value is null
• If a Property in properties is set to DEFAULT, then it will appear in the result iff the default value is not null.
• If a property does not appear in properties at all, then it will appear in the result iff its default value is not null. (Thus, specifying a property to have the DEFAULT value is the same as not specifying it at all.)

getOnlySpecifiedProperties

public Properties getOnlySpecifiedProperties(CatalogName catalog,
                                             String catalogNameForDiagnostics,
                                             Iterable<Property> properties,
                                             Session session,
                                             PlannerContext plannerContext,
                                             AccessControl accessControl,
                                             Map<NodeRef<Parameter>,Expression> parameters)

Evaluate properties. Unlike getProperties(io.trino.connector.CatalogName, java.lang.String, java.lang.Iterable<io.trino.sql.tree.Property>, io.trino.Session, io.trino.sql.PlannerContext, io.trino.security.AccessControl, java.util.Map<io.trino.sql.tree.NodeRef<io.trino.sql.tree.Parameter>, io.trino.sql.tree.Expression>), a property appears in the returned result iff it is specified in properties.
