MockCatalogReader

public static class MockCatalogReader.MockRelViewTable
extends MockCatalogReader.MockTable

Mock implementation of Prepare.AbstractPreparingTable which holds ViewTable and delegates MockCatalogReader.MockTable.toRel(org.apache.calcite.plan.RelOptTable.ToRelContext) call to the view.

Method Details

create

public static MockCatalogReader.MockRelViewTable create(ViewTable viewTable,
 MockCatalogReader catalogReader,
 String catalogName,
 String schemaName,
 String name,
 boolean stream,
 double rowCount,
 MockCatalogReader.ColumnResolver resolver)

getRowType

public RelDataType getRowType()

Description copied from interface: RelOptTable

Describes the type of rows returned by this table.

Specified by:

getRowType in interface RelOptTable

Specified by:

getRowType in interface SqlValidatorTable

Overrides:

getRowType 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
