All Implemented Interfaces:

ColumnOrderDependent, Processor<ParsingContext>, RowProcessor

public class InputValueSwitch
extends AbstractInputValueSwitch<ParsingContext>
implements RowProcessor

A concrete implementation of RowProcessorSwitch that allows switching among different implementations of RowProcessor based on values found on the rows parsed from the input.

Constructor Summary

Constructors

Constructor and Description
InputValueSwitch() Creates a switch that will analyze the first column of rows found in the input to determine which RowProcessor to use for each parsed row
InputValueSwitch(int columnIndex) Creates a switch that will analyze a column of rows parsed from the input to determine which RowProcessor to use.
InputValueSwitch(String columnName) Creates a switch that will analyze a column in rows parsed from the input to determine which RowProcessor to use.

Method Summary

Constructor Detail

InputValueSwitch

public InputValueSwitch()

Creates a switch that will analyze the first column of rows found in the input to determine which RowProcessor to use for each parsed row

InputValueSwitch

public InputValueSwitch(int columnIndex)

Creates a switch that will analyze a column of rows parsed from the input to determine which RowProcessor to use.

Parameters:

columnIndex - the column index whose value will be used to determine which RowProcessor to use for each parsed row.

InputValueSwitch

public InputValueSwitch(String columnName)

Creates a switch that will analyze a column in rows parsed from the input to determine which RowProcessor to use.

Parameters:

columnName - name of the column whose values will be used to determine which RowProcessor to use for each parsed row.

Method Detail

wrapContext

protected final ParsingContext wrapContext(ParsingContext context)

Description copied from class: AbstractProcessorSwitch

Wraps a given parser context object that returns headers and extracted field indexes associated with a given processor in this switch.

Specified by:

wrapContext in class AbstractProcessorSwitch<ParsingContext>

Parameters:

context - the context to wrap

Returns:

a wrapped context that returns the headers and extracted field indexes from AbstractProcessorSwitch.getHeaders() and AbstractProcessorSwitch.getIndexes()
