Class DataTableKernelModelAdapter

java.lang.Object
  com.rapidminer.datatable.AbstractDataTable
      com.rapidminer.datatable.DataTableKernelModelAdapter

All Implemented Interfaces:: DataTable, Reportable, Tableable, java.lang.Iterable<DataTableRow>

public class DataTableKernelModelAdapter
extends AbstractDataTable
extends AbstractDataTable

This class can be used to use a kernel model as data table. The data is directly read from the kernel model instead of building a copy. Please note that the method for adding new rows is not supported by this type of data tables.

Method Summary
`void`	`add(DataTableRow row)` Adds the given `DataTableRow` to the table.
`int`	`getColumnIndex(java.lang.String name)` Returns the column index of the column with the given name.
`java.lang.String`	`getColumnName(int i)` Returns the name of the i-th column.
`double`	`getColumnWeight(int column)` Returns the weight of the column or Double.NaN if no weight is available.
`int`	`getNumberOfColumns()` Returns the total number of columns.
`int`	`getNumberOfRows()` Returns the total number of rows.
`int`	`getNumberOfSpecialColumns()` Returns the total number of special columns.
`int`	`getNumberOfValues(int column)` Returns the number of different values for the i-th column.
`DataTableRow`	`getRow(int index)` Returns the data table row with the given index.
`boolean`	`isDate(int index)` Indicates if the column with the given index is nominal.
`boolean`	`isDateTime(int index)` Indicates if the column with the given index is nominal.
`boolean`	`isNominal(int index)` Indicates if the column with the given index is nominal.
`boolean`	`isNumerical(int index)` Indicates if the column with the given index is nominal.
`boolean`	`isSpecial(int index)` Returns true if this column is a special column which might usually not be used for some plotters, for example weights or labels.
`boolean`	`isSupportingColumnWeights()` Returns true if this data table is supporting column weights.
`boolean`	`isTime(int index)` Indicates if the column with the given index is nominal.
`java.util.Iterator<DataTableRow>`	`iterator()` Returns an iterator over all `DataTableRow`s.
`java.lang.String`	`mapIndex(int column, int value)` If a column is nominal, the index value must be mapped to the nominal value by this method.
`int`	`mapString(int column, java.lang.String value)` If a column is nominal, the nominal value must be mapped to a (new) index by this method.
`DataTable`	`sample(int newSize)` Performs a sampling of this data table.
