Constructor Detail

MutableArrayTable

MutableArrayTable(java.lang.String name,
                  RelProtoDataType protoStoredRowType,
                  RelProtoDataType protoRowType,
                  InitializerExpressionFactory initializerExpressionFactory)

Creates a MutableArrayTable.

Parameters:

name - Name of table within its schema

protoStoredRowType - Prototype of row type of stored columns (all columns except virtual columns)

protoRowType - Prototype of row type (all columns)

initializerExpressionFactory - How columns are populated

Method Detail

getModifiableCollection

public java.util.Collection getModifiableCollection()

Description copied from interface: ModifiableTable

Returns the modifiable collection. Modifying the collection will change the table's contents.

Specified by:

getModifiableCollection in interface ModifiableTable

asQueryable

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

Description copied from interface: QueryableTable

Converts this table into a Queryable.

Specified by:

asQueryable in interface QueryableTable

getElementType

public java.lang.reflect.Type getElementType()

Description copied from interface: QueryableTable

Returns the element type of the collection that will implement this table.

Specified by:

getElementType in interface QueryableTable

getExpression

public Expression getExpression(SchemaPlus schema,
                                java.lang.String tableName,
                                java.lang.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

Parameters:

schema - Schema

tableName - Table name (unique within schema)

clazz - The desired collection class; for example Queryable.

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

unwrap

public <C> C unwrap(java.lang.Class<C> aClass)

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 AbstractTable
