Method Detail

create

public static SelectionMapper create(org.pentaho.commons.connection.IPentahoResultSet resultSet,
                                     String displayName,
                                     String displayStyle)

Creates a SelectionMapper based on an IPentahoResultSet. If the result set has 1 column, the values and display names will come from that column. If it has more than 1 column, the first column will be used for the values and the second will be used for the display names

Parameters:

resultSet - The result set to get the data from

displayName - The name used to describe the choice for this selection. Usually used as a header

Returns:

SelectionMapper if successful or null

create

public static SelectionMapper create(org.pentaho.commons.connection.IPentahoResultSet resultSet,
                                     String valueColName,
                                     String dispColName,
                                     String displayName,
                                     String displayStyle)

Creates a SelectionMapper based on an IPentahoResultSet. The columns to use for the values and display names are passed in as column names.

Parameters:

resultSet - The result set to get the data from

valueColName - The name of the column to use for the values. If null, the first column will be used

dispColName - The name of the column to use for the display names. If null, the values column will be used

displayName - The name used to describe the choice for this selection. Usually used as a header

Returns:

SelectionMapper if successful or null

create

public static SelectionMapper create(org.pentaho.commons.connection.IPentahoResultSet resultSet,
                                     int valueColIndex,
                                     int dispColIndex,
                                     String displayName,
                                     String displayStyle)

Creates a SelectionMapper based on an IPentahoResultSet. The index of the column to use for the values and display names are passed in. The index is 1 based so the first (left most) column is 1.

Parameters:

resultSet - The result set to get the data from

valueColName - The index of the column to use for the values.

dispColName - The index of the column to use for the display names. If 0 then the valueColumn will be used.

displayName - The name used to describe the choice for this selection. Usually used as a header

Returns:

SelectionMapper if successful or null

create

displayName - The name used to describe the choice for this selection. Usually used as a header

Returns:

SelectionMapper if successful or null

createFromPropMapList

public static SelectionMapper createFromPropMapList(List aList,
                                                    String valueColName,
