Method Details

getRowType

public RelDataType getRowType(RelDataTypeFactory typeFactory)

Description copied from interface: Table

Returns this table's row type.

This is a struct type whose fields describe the names and types of the columns in this table.

The implementer must use the type factory provided. This ensures that the type is converted into a canonical form; other equal types in the same query will use the same object.

Specified by:

getRowType in interface Table

Parameters:

typeFactory - Type factory with which to create the type

Returns:

Row type

iterator

public Iterator<Object[]> iterator()

enumerator

public Enumerator<Object[]> enumerator()

asQueryable

public <T> Queryable<T> asQueryable(QueryProvider queryProvider,
 SchemaPlus schema,
 String tableName)

Description copied from interface: QueryableTable

Converts this table into a Queryable.

Specified by:

asQueryable in interface QueryableTable

toRel

public RelNode toRel(RelOptTable.ToRelContext context,
 RelOptTable relOptTable)

Description copied from interface: TranslatableTable

Converts this table into a relational expression.

Specified by:

toRel in interface TranslatableTable

getExpression

public Expression getExpression(SchemaPlus schema,
 String tableName,
 Class clazz)

Description copied from interface: QueryableTable

Generates an expression with which this table can be referenced in generated code.

Specified by:

getExpression in interface QueryableTable

Overrides:

getExpression in class AbstractQueryableTable

Parameters:

schema - Schema

tableName - Table name (unique within schema)

clazz - The desired collection class; for example Queryable.
