Method Detail

getPurposeString

public String getPurposeString()

Description copied from interface: OptionHandler

Gets the purpose of this object

Specified by:

getPurposeString in interface OptionHandler

Overrides:

getPurposeString in class AbstractOptionHandler

Returns:

the string with the purpose of this object

getTaskResultType

public Class<?> getTaskResultType()

Defines the task's result type.

Returns:

a class object of the result of this task

doMainTask

protected Object doMainTask(TaskMonitor monitor,
                ObjectRepository repository)

Description copied from class: MainTask

This method performs this task. AbstractTask implements doTask, that uses doTaskImpl. MainTask implements doTaskImpl using doMainTask so its extensions only need to implement doMainTask.

Specified by:

doMainTask in class MainTask

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use

Returns:

an object with the result of this task
