类 CsvFilterableTable

java.lang.Object

org.apache.calcite.schema.impl.AbstractTable

org.apache.calcite.adapter.csv.CsvTable

org.apache.calcite.adapter.csv.CsvFilterableTable

所有已实现的接口:

org.apache.calcite.schema.FilterableTable, org.apache.calcite.schema.Table, org.apache.calcite.schema.Wrapper

public class CsvFilterableTable
extends CsvTable
implements org.apache.calcite.schema.FilterableTable

Table based on a CSV file that can implement simple filtering.

It implements the FilterableTable interface, so Calcite gets data by calling the scan(DataContext, List) method.
