                                          java.lang.Long limit)

Executes an OQL query on the underlying table.

Called by the GeodeTable.GeodeQueryable which in turn is called via the generated code.

Parameters:

clientCache - Geode client cache

fields - List of fields to project

predicates - A list of predicates which should be used in the query

Returns:

Enumerator of results

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

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

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
