Constructor Detail

SimpleStatisticOutput

protected SimpleStatisticOutput()

Internal constructor for Jsonable deserialization.

SimpleStatisticOutput

public SimpleStatisticOutput(File out)
                      throws FileNotFoundException

Initializes a SimpleStatisticOutput with no statistics. The statistics need to be set later on.

Parameters:

out - The output stream that is used for the output.

Throws:

FileNotFoundException - If the given file object does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file

SimpleStatisticOutput

public SimpleStatisticOutput(File out,
                             StatisticComponent statistics)
                      throws FileNotFoundException

Initializes the SimpleStatisticOutput.

Parameters:

out - The file that is used for the output.

statistics - The StatisticComponent instance that provides all the statistics.

Throws:

FileNotFoundException - If the given file object does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file

SimpleStatisticOutput

public SimpleStatisticOutput(OutputStream out)

Initializes a SimpleStatisticOutput with no statistics. The statistics need to be set later on.

Parameters:

out - The output stream that is used for the output.

SimpleStatisticOutput

public SimpleStatisticOutput(OutputStream out,
                             StatisticComponent statistics)

Initializes the SimpleStatisticOutput.

Parameters:

out - The file that is used for the output.

statistics - The StatisticComponent instance that provides all the statistics.
