Method Details

getConstraint

protected abstract RexNode getConstraint(RexBuilder rexBuilder,
 RelDataType tableRowType)

onRegister

public void onRegister(RelDataTypeFactory typeFactory)

Overrides:

onRegister in class MockCatalogReader.MockTable

toRel

public RelNode toRel(RelOptTable.ToRelContext context)

Description copied from interface: RelOptTable

Converts this table into a relational expression.

The planner calls this method to convert a table into an initial relational expression, generally something abstract, such as a LogicalTableScan, then optimizes this expression by applying rules to transform it into more efficient access methods for this table.

Specified by:

toRel in interface RelOptTable

Overrides:

toRel in class MockCatalogReader.MockTable

unwrap

public <T> T unwrap(Class<T> clazz)

Description copied from interface: Wrapper

Finds an instance of an interface implemented by this object, or returns null if this object does not support that interface.

Specified by:

unwrap in interface Wrapper

Overrides:

unwrap in class MockCatalogReader.MockTable
