CsvFilterableTable (Apache Calcite API)

java.lang.Object
- org.apache.calcite.schema.impl.AbstractTable
- - org.apache.calcite.adapter.csv.CsvTable
  - - org.apache.calcite.adapter.csv.CsvFilterableTable

All Implemented Interfaces:

FilterableTable, Table, Wrapper
```
public class CsvFilterableTable
extends CsvTable
implements 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.

    Description copied from interface: FilterableTable
    
    Returns an enumerator over the rows in this Table. Each row is represented as an array of its column values.
    The list of filters is mutable. If the table can implement a particular filter, it should remove that filter from the list. If it cannot implement a filter, it should leave it in the list. Any filters remaining will be implemented by the consuming Calcite operator.
