Detailed Description

This class inherits from mtsTask and provides the base for implementing continuous loops, where the user-supplied Run method is repeatedly invoked. It also introduces the possibility to create a new thread or to use an existing thread for the task.

typedef mtsTask mtsTaskContinuous::BaseType

Constructor & Destructor Documentation

mtsTaskContinuous::mtsTaskContinuous	(	const std::string &	name,
		unsigned int	sizeStateTable = `256`,
		bool	newThread = `true`
	)

Create a task with name 'name' that has a state table of the specified size.

Parameters

name	The name of the task
sizeStateTable	The history size of the state table
newThread	True if a new thread should be created for this task

Note: See note in mtsTask regarding length of string name.

If newThread is false, the task will not create a new thread, but will rather "capture" an existing thread. This is done as follows:

1) Call mtsTaskContinuous::Create from the thread to be captured. The class will get the thread id for the current thread and use it to initialize all interfaces in mtsTask::StartupInternal. Once this is done, Create returns to the calling thread.

2) Call mtsTaskContinuous::Start from the thread to be captured. This function captures the thread, and uses it to call the mtsTask::Run method. It does not return until the task is terminated.

Other tasks can use mtsTask::Suspend and mtsTask::Start to suspend and resume this task, or mtsTask::Kill to terminate it. In other words, once started the task should behave the same regardless of whether or not a new thread was created.

Note that mtsTaskFromCallback provides another mechanism for using an existing thread. In that case, the task does not capture the thread, but just registers itself as a callback.
