Constructor Detail

TableFileWriter

private TableFileWriter(int mode)

Creates a new object in the specified mode.

Parameters:

mode - one of MODE_SINGLE or MODE_SEQUENCE

TableFileWriter

public TableFileWriter(File destination,
                       Object tableData,
                       String extension)

Create a new file writer object for a single table. The data type of tableData determines whether the model is exported or not.

If tableData is an instance of JTable, then the entire POJO is serialized.

Parameters:

destination - the target file

tableData - the table data, which may either be a full JTable object or a TableModel

extension - the extension of the target file

TableFileWriter

public TableFileWriter(File destination,
                       List<IqmDataBox> boxes,
                       String extension,
                       int mode)

Create a new file writer object for a sequence of tables.

If tableData is an instance of JTable, then the entire POJO is serialized.

Parameters:

destination - the target file

boxes - the IqmDataBox list containing the tables

extension - the extension of the target files

mode - the mode, which is required to be MODE_SEQUENCE

Throws:

IllegalArgumentException - if mode equals MODE_SINGLE

TableFileWriter

public TableFileWriter(File destination,
                       IqmDataBox table,
                       String extension)

Create a new file writer object for a single table.

Parameters:

destination - the target file

table - a IqmDataBox containing the table

extension - the extension of the target files
