All Implemented Interfaces:

RelOptConnection

Enclosing class:

SqlToRelTestBase

private static class SqlToRelTestBase.MockRelOptConnection
extends Object
implements RelOptConnection

Mock implementation of RelOptConnection, contains a SqlToRelTestBase.MockRelOptSchema.

Field Summary

private RelOptSchema

relOptSchema

Constructor Summary

SqlToRelTestBase.MockRelOptConnection(RelOptSchema relOptSchema)

Method Summary

Object	contentsAsArray(String qualifier, String tableName) 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.
RelOptSchema	getRelOptSchema() Returns the schema underlying this connection.

Method Detail

getRelOptSchema

public RelOptSchema getRelOptSchema()

Description copied from interface: RelOptConnection

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

contentsAsArray

public Object contentsAsArray(String qualifier,
                              String tableName)

Description copied from interface: RelOptConnection

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 RelOptSchema.getTableForMember(java.lang.String[])(qualifier,tableName).RelOptTable.toRel(org.eigenbase.relopt.RelOptCluster, org.eigenbase.relopt.RelOptConnection)(cluster, exp).
