Method Detail

getSaffronSchema

public SaffronSchema getSaffronSchema()

Description copied from interface: SaffronConnection

Returns the schema underlying this connection. Non-abstract classes implementing this interface must also provide public static Schema getSaffronSchemaStatic().

contentsAsArray

public Object contentsAsArray(String qualifier,
                              String tableName)

Description copied from interface: SaffronConnection

In theory, this method returns the contents of tableName as an array; in practice, it is a placeholder recognized by the optimizer to do something much more efficient. This involves calling SaffronSchema.getTableForMember(java.lang.String[])(qualifier,tableName).SaffronTable.toRel(net.sf.saffron.opt.VolcanoCluster, net.sf.saffron.core.SaffronConnection)(cluster, exp).
